A warm welcome to the [[Struct4U]] Knowledge Center!

Feel free to look around, if you have any comments or ideas please let us know via support@struct4u.com! Become a part of the [[Struct4U-community]]!

We try to keep the wiki compact. Therefore this wiki is written for you as '''structural engineer'''. So we assume a basic level of knowledge regarding mechanics, statics, FEM, materials, software etc. However we will refer to other publications/external links if you want to learn more about a specific subject.

In this '''Knowledge Center''' you can find tutorials, quickstarts and background information about all the products([[XFEM4U]], [[XBeam2D]], [[XFrame2D]], [[XConstruct]]) within the Struct4U Engineering Tools.[[File:XFEM4U-2.1-1.jpg|none|500x500px]]

Ponding

2024-05-23T22:47:13Z

Struct4U:

[[Main Page|BACK]]

== Introduction ==
This page contains information about ponding.

Since 2023 ponding is implemented in [[XFEM4U]].

The theory of the implementatie of ponding is according to the scientific insights of prof. Blaauwendraad. In the latest Heron Journal this method is implemented described in detail. [http://heronjournal.nl/67-2/3.pdf Link to heron journal]

Manual for the use of the ponding module can be opened using [https://software.struct4u.com/downloads/Documentation/Handleiding%20wateraccumulatie%20in%20XFEM4U%20V0.5.pdf this] link.

Parametric Design and Python

2024-02-02T21:12:26Z

Struct4U:

[[Main Page|BACK]]

== Introduction ==
This page contains information about Parametric Design in [[XFEM4U]] and how you can create 3D-models using Python.

We can send these models to Speckle or to XFEM4U. On this github repository you can find some examples of this using buildingpy.https://github.com/DutchSailor/Struct4U[[File:Parametric Hall.png|none|thumb|693x693px|Parametric Hall]]

== Direct Commands ==
Within XFEM4U and XFrame2D there is a function called 'DirectCommands'. You can use DirectCommands to open XFEM4U and XFrame2D from an external program like Excel or Python.

In this page you can find examples how to use this.

== Python ==
This example shows how to create a 3D-model in XFEM4U using Python. We use the open source Python Interpreter PyCharm Community Edition. You can download PyCharm [https://www.jetbrains.com/pycharm/ here].

We use the opensource library [https://github.com/3BMLabs/building.py BuildingPy]. In this library there are classes like point, vector, line, polycurve, panel, beam, support, loads etcetera. From this library we create objects for our 3D-model.

Examplefiles can be downloaded on github using [https://github.com/DutchSailor/Struct4U this link.]

== Example 1 ==
[[File:Python1.png|745x745px]]
Result of the Python Script

[[File:Python2.png|744x744px]]

This is the Pythoncode in PyCharm.

Below the Pythoncode with comments included per line of code.

from bp_single_file import *

#bp_single_file is a single pythonfile required to create the 3D-model in XFEM4U. THere is dependency on Numpy.

project = BuildingPy("Struct4U Example file","0")

#create a project with a name and project number

height = 3000

#In this case the height is a variable in this structure

#CREATE GRIDSYSTEM

gridinput = ["0 1000 1000",seqChar,"0 4x3600",seqNumber,"0"]

#This the syntax for a gridsystem. It is the same syntax used in XFEM4U.

#CONCRETE BEAM

project.objects.append(Frame.byStartpointEndpoint(Point(0,0,0),Point(0,14400,0),Rectangle("350x500",350,500).curve,"350x500",0,BaseConcrete))

project.objects.append(Frame.byStartpointEndpoint(Point(0,14400,0),Point(2000,14400,0),Rectangle("350x500",350,500).curve,"350x500",0,BaseConcrete))

#Here we create 2 rectangle concrete beams. Coordinates are used an profiles.

#STEEL COLUMN

project.objects.append(Frame.byStartpointEndpointProfileNameShapevector(Point(2000,14400,0),Point(2000,14400,height),"HEA160","HEA160",Vector2(0,0),0,BaseSteel,"Frame"))

#Here we create a steel column. For a HEA160 you can use the syntax of 'HEA 160, HE160A, hea 280 etc.

#Other steelprofiles are HEB100, HEM100, IPE100, 100AA, HD260/54,1, DIN, DIE, DIR, DIL, UNP, B42.4/2.6, INP.

#For the full list of profiles see: <nowiki>https://github.com/3BMLabs/building.py/blob/main/library/profile_database/steelprofile.json</nowiki>

#Composite profiles are not yet implemented.

#STEEL FRAMES

XFEM4U Load generator

2023-12-11T09:52:08Z

Struct4U:

[[Documentation XFEM4U | BACK]]

With the load generator you generate all snow and wind loads, including all load combinations, in no time. In particular, wind loads according to Eurocode are extensive and therefore laborious. The load generator takes that work out of your hands.

Before you start the load generator, you will first have to enter all the [[XFEM4U Outer Panels|Outer Panels]]

[[File:XFEM4ULoadGenerator.png|515x515px]]

'''Design working life'''

The design working life of the building in years

'''Imperfections'''

It can be set whether you want to take imperfections into account or not.

'''Wind loads according to EN-1991-1-4'''

'''Wind zone'''

Dependent on the location of the structure, the wind zone is chosen. This value differs per country.

'''Terrain category'''

Based on local circumstances the terrain category is chosen.

'''Height above terrain'''

The height of the building above terrain in meters.

'''Velocity pressure'''

Calculated velocity pressure

'''Structural factor'''

Structural factor according to 6.3

'''Correlation'''

Setting or wind pressures on facades must be reduced by 0.85. E.g. according to Dutch NAD art. 7.2.2(3).

'''Wind in +X'''

Select whether the wind has to be generated in positive x-direction.

'''Wind in -X'''

Select whether the wind has to be generated in negative x-direction.

'''Wind in +Y'''

Select whether the wind has to be generated in positive y-direction.

'''Wind in -Y'''

Select whether the wind has to be generated in negative y-direction.

The internal under- and over pressure is dependent on the size of the openings in the walls.

'''Snow loads according to EN-1991-1-3'''

Select whether the snow load needs to be generated or not.

All the load cases and load combinations for snow and wind are created automatically. You can also change and extend these loads.

To work with surface loads, there are a few '''important ground rules''', though. What you need to know.

* To work with the load generator, shells must be entered. From the shells the surface loads are generated. Shells must be drawn clockwise from the outside so that the z-axis of the shell faces outward.

* The shell (and therefore the surface load) must always be "'''edged'''" by surface load bearing beams. Even if the load (by load bearing direction) does not go there.

* Work accurately. All beams / nodes must lie neatly in the plane of the shell resp. surface load. A skewed plane is not supported. So this requires you to work accurately.

* Also, always check that the beam loads are properly generated from the surface loads. You do this by turning on "'''Derived beam loads'''". Check if the direction of the load transfer is entered correctly. If it is not correct, change the direction of the load transfer at the shells and restart the load generator.

New features

2023-09-11T22:40:07Z

Struct4U:

[[Main Page|BACK]]

This page contains the new features within the Struct4U Engineering Tools. Only the main new features are noticed.

== XFrame2D, XBeam2D 2024.2 september 2023 ==
Improved UI

XML Import/Export including bar loads and node loads. This is a very useful tool for manufacturers and suppliers with repetitive structural calculations. These can be controlled via Python, Excel or an external program

Grid and level functionality has been improved

Bar loads can be graphically adjusted and dragged better

Spy improved

Pan, zoom, copy and arrays now works like XFEM4U and takes less clicks

== XFEM4U 2024.3 september 2023 ==

==== XFEM4U 2024.3 ====

==== Hinged connection in plates ====
Plate elements were always calculated as continuous and moment fixed. New is that plate edges can be entered and calculated as hinged.
[[File:ScharnierPlaat.png|none|thumb|767x767px]]
[[File:HingePlate.png|none|thumb|767x767px]]

==== Improved graphical input of bar loads using dimension lines ====

==== Draw guide lines ====
It is possible to enter drawing guide lines. Guide lines can be very convenient when entering your construction. A display option has been added so you can show or hide these guide lines.
[[File:Guide lines.png|none|thumb|767x767px]]

==== New look and feel user interface ====
The user interface has a new look and feel. Modern and functional. We are now using the new "skin" "The Bezier" which renders its elements with vectors. This means resolution independence and sharp rendering on Hi-DPI displays. This is not only nice to work with but also less tiring. It is also possible to set the colors yourself. The menu will contain more items. To keep it clear for the user, the menu groups Geometry and Loads are automatically minimized depending on which tab is active. All to make the user-friendliness of the software even better.
[[File:New UI.png|none|thumb|914x914px]]

==== Improved display options ====
Display option: The color scale profiles now list the material name after the profile name.

The Geometry tab displays information about the model (number of beams, plates, etc.) right at the bottom.
[[File:NoElements.png|none|thumb|483x483px]]

==== Improved plates entry ====
Plates/walls: The entry has been modified. Now the dialog box will be displayed on closing the contour line. This way of working is more intuitive. And it also means that, among other things, the mesh size can be set or adjusted directly.

==== Improved concrete module ====

== Struct4U Engineering Tools 2024.2 03-07-2023 ==

=== XFEM4U 2024.2 ===

==== '''Elastic supporting beams / beams on an elastic soil.''' ====
It is possible to specify an elastic soil for each beam. The elastic soil is schematized as a series of springs that can only absorb positive reactions. Possible "loosening" is therefore provided. The spring spacing can be influenced. The modulus of subgrade reaction (kN/m3 ) is automatically converted to springs with the appropriate spring value (kN/m). The generated springs are drawn transparently.
[[File:XFEM4U ElasticSoil.png|none|thumb|1000x1000px]]
[[File:XFEM4U ElasticSoil-2.png|none|thumb|1000x1000px]]

==== Representation of elastic soil under plate ====
For plates on an elastic soil, the generated springs are drawn transparently per mesh node. In the view options, turn on "Node of plate mesh" to have all springs drawn. The elastic soil can be displayed properly that way.
[[File:XFEM4U ElasticSoilUnderPlate-1.png|none|thumb|1000x1000px]]

==== Display of plate stresses and forces ====
It is now possible to display values within a certain range by entering the maximum and/or minimum value. For example, you can display only those elements with a bending stress greater than 100 N/mm2.
[[File:XFEM4U Display of Plate Stresses.png|none|thumb|1000x1000px]]

==== Surface loads ====
It is checked whether the surface load falls into a plate. If so, no beam loads are generated. However, the detection of whether a surface load fell into a plate was not good which in some cases also resulted in no beam loads being generated. This has been resolved. (helpdesk #1829)

=== XFrame2D 2024.1, XBeam2D 2024.1 ===

==== Load generator ====
It is now possible to enter the base wind velocity Vb0 for other countries so that wind loads can be generated.

Our profile database has expanded the old steel profiles DIN, DIE, DIL and DIR.

=== XConstruct 2024.1 ===

==== Roof spigot ====
Calculation of a roof spigot is added as a new module.
[[File:XConstruct-Spuwer.png|none|thumb|1000x1000px]]

==== Wood Framing Wall Stability check ====
is added as a new module. With this module you can quickly test the stability of your wood framing wall. This module contains the calculation of a wall according to Method A of the Eurocode 5 H 9.2.4.2. With this method you can test the shear strength of an HSB wall.
[[File:XConstruct-HSB-1.png|none|thumb|1000x1000px]]

=== General ===
The Error handler has been improved which leads to more stable programs.

== Struct4U Engineering Tools 2024. 20-04-2023 ==

=== Ponding ===
It is now possible to calculate [[ponding]] of structures in 3D in [[XFEM4U]].
[[File:Ponding.png|none|thumb|700x700px]]
[[File:Ponding-1.png|none|thumb|312x312px]]
We are currently working on a proper documentation and instructions which will soon be available.

=== Orthotropic Plates ===
'''Orthropic Plates''' can be now be calculated.[[File:Orthotropic Plate.png|none|frame]]

=== Section Box ===
As in Autodesk Revit, you can use a Section Box to limit the visibility of the model. The objects of the model inside the section box are still visible, what is outside it is no longer visible.
[[File:Sectionbox.png|none|thumb|882x882px]]

=== Match properties ===
(a new right-click function) Match properties allows you to quickly and easily copy all beam data from a selected beam.

The cursor changes. Now click on the other beam to copy that data. Right-click or ESC disables this function.

<youtube>wtnXeJgqFKY</youtube>

'''XML-Export improved'''

The XML-export and XML-import has been expanded. Now you can export and import Panels, Load Cases, Beam Loads, Node Loads, Surface Loads and Load Combinations.
[[File:XML.png|none|thumb|422x422px]]

'''Struct4U Python Examples'''

With the Struct4U Speckle Server and the XML-interface in XFEM4U we can create parametric models using Python.

We can send these models to Speckle or to XFEM4U. On this github repository you can find some examples of this using buildingpy.https://github.com/DutchSailor/Struct4U
[[File:Raatligger.png|none|thumb|542x542px|Castellated Beam]]
[[File:Parametric Hall.png|none|thumb|1258x1258px|Parametric Hall]]

=== Display options ===
The display options window is restructured and improved. The functions are ordered per category.
[[File:Display_Options.png|none|frame]]

=== Speckle 3D ===
At Struct4U we have our own Speckle Server. https://www.struct4u.xyz More information about Speckle can be found here: https://speckle.systems/

You can create a free account on our server and use it to share models with clients or other participants within the design proces.
[[File:Struct4U Speckle Server.png|none|frame]]Have a look at this example model: https://struct4u.xyz/streams/3fff8f56cc/commits/3177c0c237

=== Hinged connection in plates ===

=== Meshing plates ===
Plate meshing has been greatly improved in a number of aspects.

=== DXF Underlay ===

* In the view options a button has been added to add the DXF underlay immediately. An existing overlay can also be deleted with the same button. (helpdesk #1683)

* You can move and rotate a DXF underlay. Often the coordinate system in the DXF file is different than in your model. So now you can move and rotate it. (helpdesk #1730)

=== License Server ===
To make communication via our web API with our License Server even more secure, TLS 1.2 (Transport Layer Security) is now being used. (helpdesk #1737)

=== Snap perpendicular ===

=== Other Improvements ===
# In the graphic you could already display the ('''Min./Max.)''' reaction forces. What is new is that you can now display the (Min.) reaction forces and/or the (Max.) reaction forces. (helpdesk #1691) For new projects, the '''snapsize''' is read in from the ini file. (helpdesk #1681)
# The '''snapsize''' can also be read from the XML file. (helpdesk #1681)
# When the '''display options''' was turned off it could not be opened. An error message "The dock manager is not yet initialized" appeared. This has been resolved. (helpdesk #1710/#1711)
# '''Load generator - snow load''': The roof pitch was not properly determined resulting also in mu1 and subsequently snow load. For steep roofs, this caused the magnitude of snow load to be too high (conservative). This has been solved. (helpdesk #1716)
# The '''torsional moment of inertia''' Ix for rectangular cross section was not properly determined. This has been resolved. (helpdesk #1720)
# '''Surface loads''': Selecting surface loads has been improved. When you click on one of the components, all are selected as a "block".
# '''Q beam load''': Selecting the q load has been improved. Clicking on any of the components will select all as a "block"
# '''Large shear forces''' developed in a tapered profile. The cause: A tapered profile is approximated by dividing it into a number of sub beams, each with a different moment of inertia. A beam is also divided when nodes are found on the beam. In this case, it occurred that the nodes generated were too close to existing nodes, making the partial beams very short and causing computational problems. This was solved by checking that the nodes to be generated do not get too close (within snap distance) to existing nodes. (helpdesk #1738)
# Adding a '''plate''': When you ended drawing a plate after entering 1 or 2 nodes with the right mouse button, the program hung. This has been fixed. (helpdesk #1451 en #1734)
# You could already set the number of '''decimals''' of forces and displacements. The sum of forces and largest displacements (bottom right of the screen) did not change with it. This has been solved. (helpdesk #1416)
# On the '''Load''' tab, it could happen that you unintentionally deleted also a beam, for example, due to a wrong selection. This has been improved. Now the question is always asked when you did not select only loads. (helpdesk #1754)
# For a '''large''' '''number''' of combinations, the table combinations was not printing correctly in all cases. This has been resolved. (helpdesk #1756)
# When using the "'''Hinge'''" menu option, the beam load(s) were not split properly. For example a q-load was running through across the 2 beams causing erroneous mechanics results. This has been resolved. (helpdesk #1763)
# A serious error was found with a '''surface''' '''load''' on a roof surface at exactly 45 degrees. Mathematically, the sign of the load flipped, causing the load to be in the wrong direction. This error has been corrected. (helpdesk #1766)
# After a zoom selection the selection remained. This has been improved.
# '''XML import''': Import of nodes was not quite correct. This has been improved.
# In specific cases beam and node numbers of transparent drawn beams were shown. This has been improved. Beam and node numbers are never shown when the beam itself is drawn transparent. (helpdesk #1775)
# When '''joining''' '''nodes''' within the snap distance (CheckOnCoincidingNodes function), the cross-sectional size of the connecting beams in the node is now considered. In this way, the nodes of the main supporting structure are given more priority (weight). (helpdesk #1789)
# For '''views''' of '''grids''' and levels, the remaining beams were drawn transparently. For large construction, this was not clear. This has been improved. Now other beams are no longer drawn transparently. You can still show them by enabling "Draw hidden layers layers transparent". (helpdesk #1782)
# Meshing of plates: When the nodes of the plate contour were not completely in a plane, the mesh nodes were not taken together with the nodes of the plate contour. This has been improved. The testing of the distance between nodes has been increased from 1 mm to 5 mm. (helpdesk #1799)
# When you '''copy''' a '''beam''' with the function Visibility switch on the new beam is not drawn visible. This has been fixed. (helpdesk #1804)
# '''Plates''': The modulus of elasticity at material Other could not be adjusted. This has been resolved. (helpdesk #1802)
# '''Snapping''' to '''beams''' has been further extended to include a snap to the intersection with the lines of the DXF underlay, and the grid lines. (helpdesk #1764)
# When a plate is removed and re-entered, all data (slab thickness, concrete grade, etc.) is '''remembered'''. (helpdesk #1753)
# A '''triangular''' plate was not drawn as solid. This has been fixed. (helpdesk #1736)
# '''Concrete''': The determination of the maximum value in the color scale of the reinforcement quantities (Asxt, Asyt, Asxb, Asyb and Asw) did not examine whether the plates (using layers) were visible or not. This has been improved. (helpdesk #1742)
# '''Steel''' When the steel standard was off in the calculation settings, the program broke down when printing the yield strength. This problem has been resolved. (helpdesk #1697)
# '''Steel''' In specific cases, reduction factor for lateral-torsional buckling χLT could become greater than 1.00. This is obviously not possible and has been adjusted. (helpdesk #1745)
# '''Steel''' Beam-column moment connection - butt joint: The stiffness of the end plate was charged 1x instead of 2x. This has been resolved. (helpdesk #1666)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation the bolt length was not correctly determined This is solved. (helpdesk #1667)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation a stiffness modification factor of 2 instead of 3 was used.
# '''Timber''' Columns were also always tested according to Art. 6.2.4. This turned out to be incorrect. Formulas (6.19) and (6.20) should be used only when lambda;rel,z < 0.3 and lambda;rel,y < 0.3. This has been fixed. (helpdesk #1698)

|'''Improvement of the implementation of the NEN-EN 1993'''
Lateral buckling stability: I-shaped sections were tested according to formula (6.56) of article 6.3.2.2.

This is a conservative and therefore safe calculation.

However, for I-sections it is also possible to use formulae (6.57) and (6.58) of article 6.3.2.3.

Generally this leads to lower / more favorable unity checks.

And we have now provided that.

This can further optimize the design of your steel structure and save steel weight.

New features

2023-09-05T05:31:00Z

Struct4U:

[[Main Page|BACK]]

This page contains the new features within the Struct4U Engineering Tools. Only the main new features are noticed.

== Struct4U Engineering Tools 2024.3 september 2023 ==

==== XFEM4U 2024.3 ====

==== Hinged connection in plates ====
Plate elements were always calculated as continuous and moment fixed. New is that plate edges can be entered and calculated as hinged.
[[File:ScharnierPlaat.png|none|thumb|767x767px]]
[[File:HingePlate.png|none|thumb|767x767px]]

==== Improved graphical input of bar loads using dimension lines ====

==== Draw guide lines ====
It is possible to enter drawing guide lines. Guide lines can be very convenient when entering your construction. A display option has been added so you can show or hide these guide lines.

==== New look and feel user interface ====
The user interface has a new look and feel. Modern and functional. We are now using the new "skin" "The Bezier" which renders its elements with vectors. This means resolution independence and sharp rendering on Hi-DPI displays. This is not only nice to work with but also less tiring. It is also possible to set the colors yourself. The menu will contain more items. To keep it clear for the user, the menu groups Geometry and Loads are automatically minimized depending on which tab is active. All to make the user-friendliness of the software even better.
[[File:New UI.png|none|thumb|914x914px]]

==== Improved display options ====
Display option: The color scale profiles now list the material name after the profile name.

The Geometry tab displays information about the model (number of beams, plates, etc.) right at the bottom.
[[File:NoElements.png|none|thumb|483x483px]]

==== Improved plates entry ====
Plates/walls: The entry has been modified. Now the dialog box will be displayed on closing the contour line. This way of working is more intuitive. And it also means that, among other things, the mesh size can be set or adjusted directly.

==== Improved concrete module ====

=== XFEM4U 2024.2 ===

==== '''Elastic supporting beams / beams on an elastic soil.''' ====
It is possible to specify an elastic soil for each beam. The elastic soil is schematized as a series of springs that can only absorb positive reactions. Possible "loosening" is therefore provided. The spring spacing can be influenced. The modulus of subgrade reaction (kN/m3 ) is automatically converted to springs with the appropriate spring value (kN/m). The generated springs are drawn transparently.

[[File:XFEM4U ElasticSoil-2.png|none|thumb|1000x1000px]]

==== Representation of elastic soil under plate ====
For plates on an elastic soil, the generated springs are drawn transparently per mesh node. In the view options, turn on "Node of plate mesh" to have all springs drawn. The elastic soil can be displayed properly that way.
[[File:XFEM4U ElasticSoilUnderPlate-1.png|none|thumb|1000x1000px]]

==== Display of plate stresses and forces ====
It is now possible to display values within a certain range by entering the maximum and/or minimum value. For example, you can display only those elements with a bending stress greater than 100 N/mm2.
[[File:XFEM4U Display of Plate Stresses.png|none|thumb|1000x1000px]]

==== Surface loads ====
It is checked whether the surface load falls into a plate. If so, no beam loads are generated. However, the detection of whether a surface load fell into a plate was not good which in some cases also resulted in no beam loads being generated. This has been resolved. (helpdesk #1829)

=== XFrame2D 2024.1, XBeam2D 2024.1 ===

==== Load generator ====
It is now possible to enter the base wind velocity Vb0 for other countries so that wind loads can be generated.

Our profile database has expanded the old steel profiles DIN, DIE, DIL and DIR.

=== XConstruct 2024.1 ===

==== Roof spigot ====
Calculation of a roof spigot is added as a new module.
[[File:XConstruct-Spuwer.png|none|thumb|1000x1000px]]

==== Wood Framing Wall Stability check ====
is added as a new module. With this module you can quickly test the stability of your wood framing wall. This module contains the calculation of a wall according to Method A of the Eurocode 5 H 9.2.4.2. With this method you can test the shear strength of an HSB wall.
[[File:XConstruct-HSB-1.png|none|thumb|1000x1000px]]

=== General ===
The Error handler has been improved which leads to more stable programs.

== Struct4U Engineering Tools 2024. 20-04-2023 ==

=== Ponding ===
It is now possible to calculate [[ponding]] of structures in 3D in [[XFEM4U]].
[[File:Ponding.png|none|thumb|700x700px]]
[[File:Ponding-1.png|none|thumb|312x312px]]
We are currently working on a proper documentation and instructions which will soon be available.

=== Orthotropic Plates ===
'''Orthropic Plates''' can be now be calculated.[[File:Orthotropic Plate.png|none|frame]]

=== Section Box ===
As in Autodesk Revit, you can use a Section Box to limit the visibility of the model. The objects of the model inside the section box are still visible, what is outside it is no longer visible.
[[File:Sectionbox.png|none|thumb|882x882px]]

=== Match properties ===
(a new right-click function) Match properties allows you to quickly and easily copy all beam data from a selected beam.

The cursor changes. Now click on the other beam to copy that data. Right-click or ESC disables this function.

'''XML-Export improved'''

The XML-export and XML-import has been expanded. Now you can export and import Panels, Load Cases, Beam Loads, Node Loads, Surface Loads and Load Combinations.
[[File:XML.png|none|thumb|422x422px]]

'''Struct4U Python Examples'''

With the Struct4U Speckle Server and the XML-interface in XFEM4U we can create parametric models using Python.

We can send these models to Speckle or to XFEM4U. On this github repository you can find some examples of this using buildingpy.https://github.com/DutchSailor/Struct4U
[[File:Raatligger.png|none|thumb|542x542px|Castellated Beam]]
[[File:Parametric Hall.png|none|thumb|1258x1258px|Parametric Hall]]

=== Display options ===
The display options window is restructured and improved. The functions are ordered per category.
[[File:Display_Options.png|none|frame]]

=== Speckle 3D ===
At Struct4U we have our own Speckle Server. https://www.struct4u.xyz More information about Speckle can be found here: https://speckle.systems/

You can create a free account on our server and use it to share models with clients or other participants within the design proces.

=== Hinged connection in plates ===

=== Meshing plates ===
Plate meshing has been greatly improved in a number of aspects.

=== DXF Underlay ===

* In the view options a button has been added to add the DXF underlay immediately. An existing overlay can also be deleted with the same button. (helpdesk #1683)

* You can move and rotate a DXF underlay. Often the coordinate system in the DXF file is different than in your model. So now you can move and rotate it. (helpdesk #1730)

=== License Server ===
To make communication via our web API with our License Server even more secure, TLS 1.2 (Transport Layer Security) is now being used. (helpdesk #1737)

=== Snap perpendicular ===

=== Other Improvements ===
# In the graphic you could already display the ('''Min./Max.)''' reaction forces. What is new is that you can now display the (Min.) reaction forces and/or the (Max.) reaction forces. (helpdesk #1691) For new projects, the '''snapsize''' is read in from the ini file. (helpdesk #1681)
# The '''snapsize''' can also be read from the XML file. (helpdesk #1681)
# When the '''display options''' was turned off it could not be opened. An error message "The dock manager is not yet initialized" appeared. This has been resolved. (helpdesk #1710/#1711)
# '''Load generator - snow load''': The roof pitch was not properly determined resulting also in mu1 and subsequently snow load. For steep roofs, this caused the magnitude of snow load to be too high (conservative). This has been solved. (helpdesk #1716)
# The '''torsional moment of inertia''' Ix for rectangular cross section was not properly determined. This has been resolved. (helpdesk #1720)
# '''Surface loads''': Selecting surface loads has been improved. When you click on one of the components, all are selected as a "block".
# '''Q beam load''': Selecting the q load has been improved. Clicking on any of the components will select all as a "block"
# '''Large shear forces''' developed in a tapered profile. The cause: A tapered profile is approximated by dividing it into a number of sub beams, each with a different moment of inertia. A beam is also divided when nodes are found on the beam. In this case, it occurred that the nodes generated were too close to existing nodes, making the partial beams very short and causing computational problems. This was solved by checking that the nodes to be generated do not get too close (within snap distance) to existing nodes. (helpdesk #1738)
# Adding a '''plate''': When you ended drawing a plate after entering 1 or 2 nodes with the right mouse button, the program hung. This has been fixed. (helpdesk #1451 en #1734)
# You could already set the number of '''decimals''' of forces and displacements. The sum of forces and largest displacements (bottom right of the screen) did not change with it. This has been solved. (helpdesk #1416)
# On the '''Load''' tab, it could happen that you unintentionally deleted also a beam, for example, due to a wrong selection. This has been improved. Now the question is always asked when you did not select only loads. (helpdesk #1754)
# For a '''large''' '''number''' of combinations, the table combinations was not printing correctly in all cases. This has been resolved. (helpdesk #1756)
# When using the "'''Hinge'''" menu option, the beam load(s) were not split properly. For example a q-load was running through across the 2 beams causing erroneous mechanics results. This has been resolved. (helpdesk #1763)
# A serious error was found with a '''surface''' '''load''' on a roof surface at exactly 45 degrees. Mathematically, the sign of the load flipped, causing the load to be in the wrong direction. This error has been corrected. (helpdesk #1766)
# After a zoom selection the selection remained. This has been improved.
# '''XML import''': Import of nodes was not quite correct. This has been improved.
# In specific cases beam and node numbers of transparent drawn beams were shown. This has been improved. Beam and node numbers are never shown when the beam itself is drawn transparent. (helpdesk #1775)
# When '''joining''' '''nodes''' within the snap distance (CheckOnCoincidingNodes function), the cross-sectional size of the connecting beams in the node is now considered. In this way, the nodes of the main supporting structure are given more priority (weight). (helpdesk #1789)
# For '''views''' of '''grids''' and levels, the remaining beams were drawn transparently. For large construction, this was not clear. This has been improved. Now other beams are no longer drawn transparently. You can still show them by enabling "Draw hidden layers layers transparent". (helpdesk #1782)
# Meshing of plates: When the nodes of the plate contour were not completely in a plane, the mesh nodes were not taken together with the nodes of the plate contour. This has been improved. The testing of the distance between nodes has been increased from 1 mm to 5 mm. (helpdesk #1799)
# When you '''copy''' a '''beam''' with the function Visibility switch on the new beam is not drawn visible. This has been fixed. (helpdesk #1804)
# '''Plates''': The modulus of elasticity at material Other could not be adjusted. This has been resolved. (helpdesk #1802)
# '''Snapping''' to '''beams''' has been further extended to include a snap to the intersection with the lines of the DXF underlay, and the grid lines. (helpdesk #1764)
# When a plate is removed and re-entered, all data (slab thickness, concrete grade, etc.) is '''remembered'''. (helpdesk #1753)
# A '''triangular''' plate was not drawn as solid. This has been fixed. (helpdesk #1736)
# '''Concrete''': The determination of the maximum value in the color scale of the reinforcement quantities (Asxt, Asyt, Asxb, Asyb and Asw) did not examine whether the plates (using layers) were visible or not. This has been improved. (helpdesk #1742)
# '''Steel''' When the steel standard was off in the calculation settings, the program broke down when printing the yield strength. This problem has been resolved. (helpdesk #1697)
# '''Steel''' In specific cases, reduction factor for lateral-torsional buckling χLT could become greater than 1.00. This is obviously not possible and has been adjusted. (helpdesk #1745)
# '''Steel''' Beam-column moment connection - butt joint: The stiffness of the end plate was charged 1x instead of 2x. This has been resolved. (helpdesk #1666)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation the bolt length was not correctly determined This is solved. (helpdesk #1667)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation a stiffness modification factor of 2 instead of 3 was used.
# '''Timber''' Columns were also always tested according to Art. 6.2.4. This turned out to be incorrect. Formulas (6.19) and (6.20) should be used only when lambda;rel,z < 0.3 and lambda;rel,y < 0.3. This has been fixed. (helpdesk #1698)

|'''Improvement of the implementation of the NEN-EN 1993'''
Lateral buckling stability: I-shaped sections were tested according to formula (6.56) of article 6.3.2.2.

This is a conservative and therefore safe calculation.

However, for I-sections it is also possible to use formulae (6.57) and (6.58) of article 6.3.2.3.

Generally this leads to lower / more favorable unity checks.

And we have now provided that.

This can further optimize the design of your steel structure and save steel weight.

Struct4U: /* Moments of Inertia of Roof sheets */

[[Main Page|BACK]]

== Introduction ==
This page contains information about ponding.

Since 2023 ponding is implemented in [[XFEM4U]].

The theory of the implementatie of ponding is according to the scientific insights of prof. Blaauwendraad. In the latest Heron Journal this method is implemented described in detail. [http://heronjournal.nl/67-2/3.pdf Link to heron journal]

Struct4U: /* Moments of Inertia of Roof sheets */

[[Main Page|BACK]]

== Introduction ==
This page contains information about ponding.

Since 2023 ponding is implemented in [[XFEM4U]].

The theory of the implementatie of ponding is according to the scientific insights of prof. Blaauwendraad. In the latest Heron Journal this method is implemented described in detail. [http://heronjournal.nl/67-2/3.pdf Link to heron journal]

New features

2023-07-04T04:56:32Z

Struct4U:

[[Main Page|BACK]]

This page contains the new features within the Struct4U Engineering Tools. Only the main new features are noticed.

== Struct4U Engineering Tools 2024.2 03-07-2023 ==

=== XFEM4U 2024. ===

==== '''Elastic supporting beams / beams on an elastic soil.''' ====
It is possible to specify an elastic soil for each beam. The elastic soil is schematized as a series of springs that can only absorb positive reactions. Possible "loosening" is therefore provided. The spring spacing can be influenced. The modulus of subgrade reaction (kN/m3 ) is automatically converted to springs with the appropriate spring value (kN/m). The generated springs are drawn transparently.
[[File:XFEM4U ElasticSoil.png|none|thumb|1000x1000px]]
[[File:XFEM4U ElasticSoil-2.png|none|thumb|1000x1000px]]

==== Representation of elastic soil under plate ====
For plates on an elastic soil, the generated springs are drawn transparently per mesh node. In the view options, turn on "Node of plate mesh" to have all springs drawn. The elastic soil can be displayed properly that way.
[[File:XFEM4U ElasticSoilUnderPlate-1.png|none|thumb|1000x1000px]]

==== Display of plate stresses and forces ====
It is now possible to display values within a certain range by entering the maximum and/or minimum value. For example, you can display only those elements with a bending stress greater than 100 N/mm2.
[[File:XFEM4U Display of Plate Stresses.png|none|thumb|1000x1000px]]

==== Surface loads ====
It is checked whether the surface load falls into a plate. If so, no beam loads are generated. However, the detection of whether a surface load fell into a plate was not good which in some cases also resulted in no beam loads being generated. This has been resolved. (helpdesk #1829)

=== XFrame2D 2024.1, XBeam2D 2024.1 ===

==== Load generator ====
It is now possible to enter the base wind velocity Vb0 for other countries so that wind loads can be generated.

Our profile database has expanded the old steel profiles DIN, DIE, DIL and DIR.

=== XConstruct 2024.1 ===

==== Roof spigot ====
Calculation of a roof spigot is added as a new module.
[[File:XConstruct-Spuwer.png|none|thumb|1000x1000px]]

==== Wood Framing Wall Stability check ====
is added as a new module. With this module you can quickly test the stability of your wood framing wall. This module contains the calculation of a wall according to Method A of the Eurocode 5 H 9.2.4.2. With this method you can test the shear strength of an HSB wall.
[[File:XConstruct-HSB-1.png|none|thumb|1000x1000px]]

=== General ===
The Error handler has been improved which leads to more stable programs.

== Struct4U Engineering Tools 2024. 20-04-2023 ==

=== Ponding ===
It is now possible to calculate [[ponding]] of structures in 3D in [[XFEM4U]].
[[File:Ponding.png|none|thumb|700x700px]]
[[File:Ponding-1.png|none|thumb|312x312px]]
We are currently working on a proper documentation and instructions which will soon be available.

=== Orthotropic Plates ===
'''Orthropic Plates''' can be now be calculated.[[File:Orthotropic Plate.png|none|frame]]

=== Section Box ===
As in Autodesk Revit, you can use a Section Box to limit the visibility of the model. The objects of the model inside the section box are still visible, what is outside it is no longer visible.
[[File:Sectionbox.png|none|thumb|882x882px]]

=== Match properties ===
(a new right-click function) Match properties allows you to quickly and easily copy all beam data from a selected beam.

The cursor changes. Now click on the other beam to copy that data. Right-click or ESC disables this function.

'''XML-Export improved'''

The XML-export and XML-import has been expanded. Now you can export and import Panels, Load Cases, Beam Loads, Node Loads, Surface Loads and Load Combinations.
[[File:XML.png|none|thumb|422x422px]]

'''Struct4U Python Examples'''

With the Struct4U Speckle Server and the XML-interface in XFEM4U we can create parametric models using Python.

We can send these models to Speckle or to XFEM4U. On this github repository you can find some examples of this using buildingpy.https://github.com/DutchSailor/Struct4U
[[File:Raatligger.png|none|thumb|542x542px|Castellated Beam]]
[[File:Parametric Hall.png|none|thumb|1258x1258px|Parametric Hall]]

=== Display options ===
The display options window is restructured and improved. The functions are ordered per category.
[[File:Display_Options.png|none|frame]]

=== Speckle 3D ===
At Struct4U we have our own Speckle Server. https://www.struct4u.xyz More information about Speckle can be found here: https://speckle.systems/

You can create a free account on our server and use it to share models with clients or other participants within the design proces.
[[File:Struct4U Speckle Server.png|none|frame]]Have a look at this example model: https://struct4u.xyz/streams/3fff8f56cc/commits/3177c0c237

=== Hinged connection in plates ===

=== Meshing plates ===
Plate meshing has been greatly improved in a number of aspects.

=== DXF Underlay ===

* In the view options a button has been added to add the DXF underlay immediately. An existing overlay can also be deleted with the same button. (helpdesk #1683)

* You can move and rotate a DXF underlay. Often the coordinate system in the DXF file is different than in your model. So now you can move and rotate it. (helpdesk #1730)

=== License Server ===
To make communication via our web API with our License Server even more secure, TLS 1.2 (Transport Layer Security) is now being used. (helpdesk #1737)

=== Snap perpendicular ===

=== Other Improvements ===
# In the graphic you could already display the ('''Min./Max.)''' reaction forces. What is new is that you can now display the (Min.) reaction forces and/or the (Max.) reaction forces. (helpdesk #1691) For new projects, the '''snapsize''' is read in from the ini file. (helpdesk #1681)
# The '''snapsize''' can also be read from the XML file. (helpdesk #1681)
# When the '''display options''' was turned off it could not be opened. An error message "The dock manager is not yet initialized" appeared. This has been resolved. (helpdesk #1710/#1711)
# '''Load generator - snow load''': The roof pitch was not properly determined resulting also in mu1 and subsequently snow load. For steep roofs, this caused the magnitude of snow load to be too high (conservative). This has been solved. (helpdesk #1716)
# The '''torsional moment of inertia''' Ix for rectangular cross section was not properly determined. This has been resolved. (helpdesk #1720)
# '''Surface loads''': Selecting surface loads has been improved. When you click on one of the components, all are selected as a "block".
# '''Q beam load''': Selecting the q load has been improved. Clicking on any of the components will select all as a "block"
# '''Large shear forces''' developed in a tapered profile. The cause: A tapered profile is approximated by dividing it into a number of sub beams, each with a different moment of inertia. A beam is also divided when nodes are found on the beam. In this case, it occurred that the nodes generated were too close to existing nodes, making the partial beams very short and causing computational problems. This was solved by checking that the nodes to be generated do not get too close (within snap distance) to existing nodes. (helpdesk #1738)
# Adding a '''plate''': When you ended drawing a plate after entering 1 or 2 nodes with the right mouse button, the program hung. This has been fixed. (helpdesk #1451 en #1734)
# You could already set the number of '''decimals''' of forces and displacements. The sum of forces and largest displacements (bottom right of the screen) did not change with it. This has been solved. (helpdesk #1416)
# On the '''Load''' tab, it could happen that you unintentionally deleted also a beam, for example, due to a wrong selection. This has been improved. Now the question is always asked when you did not select only loads. (helpdesk #1754)
# For a '''large''' '''number''' of combinations, the table combinations was not printing correctly in all cases. This has been resolved. (helpdesk #1756)
# When using the "'''Hinge'''" menu option, the beam load(s) were not split properly. For example a q-load was running through across the 2 beams causing erroneous mechanics results. This has been resolved. (helpdesk #1763)
# A serious error was found with a '''surface''' '''load''' on a roof surface at exactly 45 degrees. Mathematically, the sign of the load flipped, causing the load to be in the wrong direction. This error has been corrected. (helpdesk #1766)
# After a zoom selection the selection remained. This has been improved.
# '''XML import''': Import of nodes was not quite correct. This has been improved.
# In specific cases beam and node numbers of transparent drawn beams were shown. This has been improved. Beam and node numbers are never shown when the beam itself is drawn transparent. (helpdesk #1775)
# When '''joining''' '''nodes''' within the snap distance (CheckOnCoincidingNodes function), the cross-sectional size of the connecting beams in the node is now considered. In this way, the nodes of the main supporting structure are given more priority (weight). (helpdesk #1789)
# For '''views''' of '''grids''' and levels, the remaining beams were drawn transparently. For large construction, this was not clear. This has been improved. Now other beams are no longer drawn transparently. You can still show them by enabling "Draw hidden layers layers transparent". (helpdesk #1782)
# Meshing of plates: When the nodes of the plate contour were not completely in a plane, the mesh nodes were not taken together with the nodes of the plate contour. This has been improved. The testing of the distance between nodes has been increased from 1 mm to 5 mm. (helpdesk #1799)
# When you '''copy''' a '''beam''' with the function Visibility switch on the new beam is not drawn visible. This has been fixed. (helpdesk #1804)
# '''Plates''': The modulus of elasticity at material Other could not be adjusted. This has been resolved. (helpdesk #1802)
# '''Snapping''' to '''beams''' has been further extended to include a snap to the intersection with the lines of the DXF underlay, and the grid lines. (helpdesk #1764)
# When a plate is removed and re-entered, all data (slab thickness, concrete grade, etc.) is '''remembered'''. (helpdesk #1753)
# A '''triangular''' plate was not drawn as solid. This has been fixed. (helpdesk #1736)
# '''Concrete''': The determination of the maximum value in the color scale of the reinforcement quantities (Asxt, Asyt, Asxb, Asyb and Asw) did not examine whether the plates (using layers) were visible or not. This has been improved. (helpdesk #1742)
# '''Steel''' When the steel standard was off in the calculation settings, the program broke down when printing the yield strength. This problem has been resolved. (helpdesk #1697)
# '''Steel''' In specific cases, reduction factor for lateral-torsional buckling χLT could become greater than 1.00. This is obviously not possible and has been adjusted. (helpdesk #1745)
# '''Steel''' Beam-column moment connection - butt joint: The stiffness of the end plate was charged 1x instead of 2x. This has been resolved. (helpdesk #1666)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation the bolt length was not correctly determined This is solved. (helpdesk #1667)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation a stiffness modification factor of 2 instead of 3 was used.
# '''Timber''' Columns were also always tested according to Art. 6.2.4. This turned out to be incorrect. Formulas (6.19) and (6.20) should be used only when lambda;rel,z < 0.3 and lambda;rel,y < 0.3. This has been fixed. (helpdesk #1698)

|'''Improvement of the implementation of the NEN-EN 1993'''
Lateral buckling stability: I-shaped sections were tested according to formula (6.56) of article 6.3.2.2.

This is a conservative and therefore safe calculation.

However, for I-sections it is also possible to use formulae (6.57) and (6.58) of article 6.3.2.3.

Generally this leads to lower / more favorable unity checks.

And we have now provided that.

This can further optimize the design of your steel structure and save steel weight.

=== Match properties ===
(a new right-click function) Match properties allows you to quickly and easily copy all beam data from a selected beam.

The cursor changes. Now click on the other beam to copy that data. Right-click or ESC disables this function.

'''Struct4U Python Examples'''

With the Struct4U Speckle Server and the XML-interface in XFEM4U we can create parametric models using Python.

We can send these models to Speckle or to XFEM4U. On this github repository you can find some examples of this using buildingpy.https://github.com/DutchSailor/Struct4U

=== Speckle 3D ===
At Struct4U we have our own Speckle Server. https://www.struct4u.xyz More information about Speckle can be found here: https://speckle.systems/

You can create a free account on our server and use it to share models with clients or other participants within the design proces.

=== Hinged connection in plates ===

=== Meshing plates ===
Plate meshing has been greatly improved in a number of aspects.

=== DXF Underlay ===

* In the view options a button has been added to add the DXF underlay immediately. An existing overlay can also be deleted with the same button. (helpdesk #1683)

* You can move and rotate a DXF underlay. Often the coordinate system in the DXF file is different than in your model. So now you can move and rotate it. (helpdesk #1730)

=== License Server ===
To make communication via our web API with our License Server even more secure, TLS 1.2 (Transport Layer Security) is now being used. (helpdesk #1737)

=== Snap perpendicular ===

=== Other Improvements ===
# In the graphic you could already display the ('''Min./Max.)''' reaction forces. What is new is that you can now display the (Min.) reaction forces and/or the (Max.) reaction forces. (helpdesk #1691) For new projects, the '''snapsize''' is read in from the ini file. (helpdesk #1681)
# The '''snapsize''' can also be read from the XML file. (helpdesk #1681)
# When the '''display options''' was turned off it could not be opened. An error message "The dock manager is not yet initialized" appeared. This has been resolved. (helpdesk #1710/#1711)
# '''Load generator - snow load''': The roof pitch was not properly determined resulting also in mu1 and subsequently snow load. For steep roofs, this caused the magnitude of snow load to be too high (conservative). This has been solved. (helpdesk #1716)
# The '''torsional moment of inertia''' Ix for rectangular cross section was not properly determined. This has been resolved. (helpdesk #1720)
# '''Surface loads''': Selecting surface loads has been improved. When you click on one of the components, all are selected as a "block".
# '''Q beam load''': Selecting the q load has been improved. Clicking on any of the components will select all as a "block"
# '''Large shear forces''' developed in a tapered profile. The cause: A tapered profile is approximated by dividing it into a number of sub beams, each with a different moment of inertia. A beam is also divided when nodes are found on the beam. In this case, it occurred that the nodes generated were too close to existing nodes, making the partial beams very short and causing computational problems. This was solved by checking that the nodes to be generated do not get too close (within snap distance) to existing nodes. (helpdesk #1738)
# Adding a '''plate''': When you ended drawing a plate after entering 1 or 2 nodes with the right mouse button, the program hung. This has been fixed. (helpdesk #1451 en #1734)
# You could already set the number of '''decimals''' of forces and displacements. The sum of forces and largest displacements (bottom right of the screen) did not change with it. This has been solved. (helpdesk #1416)
# On the '''Load''' tab, it could happen that you unintentionally deleted also a beam, for example, due to a wrong selection. This has been improved. Now the question is always asked when you did not select only loads. (helpdesk #1754)
# For a '''large''' '''number''' of combinations, the table combinations was not printing correctly in all cases. This has been resolved. (helpdesk #1756)
# When using the "'''Hinge'''" menu option, the beam load(s) were not split properly. For example a q-load was running through across the 2 beams causing erroneous mechanics results. This has been resolved. (helpdesk #1763)
# A serious error was found with a '''surface''' '''load''' on a roof surface at exactly 45 degrees. Mathematically, the sign of the load flipped, causing the load to be in the wrong direction. This error has been corrected. (helpdesk #1766)
# After a zoom selection the selection remained. This has been improved.
# '''XML import''': Import of nodes was not quite correct. This has been improved.
# In specific cases beam and node numbers of transparent drawn beams were shown. This has been improved. Beam and node numbers are never shown when the beam itself is drawn transparent. (helpdesk #1775)
# When '''joining''' '''nodes''' within the snap distance (CheckOnCoincidingNodes function), the cross-sectional size of the connecting beams in the node is now considered. In this way, the nodes of the main supporting structure are given more priority (weight). (helpdesk #1789)
# For '''views''' of '''grids''' and levels, the remaining beams were drawn transparently. For large construction, this was not clear. This has been improved. Now other beams are no longer drawn transparently. You can still show them by enabling "Draw hidden layers layers transparent". (helpdesk #1782)
# Meshing of plates: When the nodes of the plate contour were not completely in a plane, the mesh nodes were not taken together with the nodes of the plate contour. This has been improved. The testing of the distance between nodes has been increased from 1 mm to 5 mm. (helpdesk #1799)
# When you '''copy''' a '''beam''' with the function Visibility switch on the new beam is not drawn visible. This has been fixed. (helpdesk #1804)
# '''Plates''': The modulus of elasticity at material Other could not be adjusted. This has been resolved. (helpdesk #1802)
# '''Snapping''' to '''beams''' has been further extended to include a snap to the intersection with the lines of the DXF underlay, and the grid lines. (helpdesk #1764)
# When a plate is removed and re-entered, all data (slab thickness, concrete grade, etc.) is '''remembered'''. (helpdesk #1753)
# A '''triangular''' plate was not drawn as solid. This has been fixed. (helpdesk #1736)
# '''Concrete''': The determination of the maximum value in the color scale of the reinforcement quantities (Asxt, Asyt, Asxb, Asyb and Asw) did not examine whether the plates (using layers) were visible or not. This has been improved. (helpdesk #1742)
# '''Steel''' When the steel standard was off in the calculation settings, the program broke down when printing the yield strength. This problem has been resolved. (helpdesk #1697)
# '''Steel''' In specific cases, reduction factor for lateral-torsional buckling χLT could become greater than 1.00. This is obviously not possible and has been adjusted. (helpdesk #1745)
# '''Steel''' Beam-column moment connection - butt joint: The stiffness of the end plate was charged 1x instead of 2x. This has been resolved. (helpdesk #1666)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation the bolt length was not correctly determined This is solved. (helpdesk #1667)
# '''Steel''' Beam-column moment connection - butt joint: In the stiffness calculation a stiffness modification factor of 2 instead of 3 was used.
# '''Timber''' Columns were also always tested according to Art. 6.2.4. This turned out to be incorrect. Formulas (6.19) and (6.20) should be used only when lambda;rel,z < 0.3 and lambda;rel,y < 0.3. This has been fixed. (helpdesk #1698)

|'''Improvement of the implementation of the NEN-EN 1993'''
Lateral buckling stability: I-shaped sections were tested according to formula (6.56) of article 6.3.2.2.

This is a conservative and therefore safe calculation.

However, for I-sections it is also possible to use formulae (6.57) and (6.58) of article 6.3.2.3.

Generally this leads to lower / more favorable unity checks.

And we have now provided that.

This can further optimize the design of your steel structure and save steel weight.
