| ===Coordinate System=== | | ===Chapters user manual=== |
| Ā | | [[Get started with the Struct4U Engineering Tools | 1. Get Started]] |
| The program knows four '''clockwise''' coordinate systems.
| |
| Ā | |
| ====Main coordinate system====
| |
| Ā | |
| The location of this global coordinate system is arbitrary. The XY-plane coincides with the plane of the framework. This coordinate system is used for setting the node coordinates, node limitations and node loads. Calculated node deformations and support reactions will be displayed relative to this coordinate system.
| |
| Ā | |
| [[File:MainCoordinates.png|200px|none|]]
| |
| Ā | |
| ====Beam coordinate system====
| |
| Ā | |
| The origin of this coordinate system is always in the beginning of the relevant beam. The XZ-plane coincides with the plane of the framework. The x-axis coincides with the beam-axis.
| |
| Ā | |
| [[File:BeamCoordinates.png|200px|none|]]
| |
| Ā | |
| ====Node coordinate system====
| |
| Ā | |
| [[File:NodeCoordinate.png|200px|none|]]
| |
| Ā | |
| It is possible to use a local (node-) coordinate system. The origin lies in the relevant node. The direction of the x-axis is determined by assigning a relative dx and dz coming from the relevant node ( see the figure above). Local coordinate systems can be used to calculate node limitations ( support reactions and restrains ), node loads and/or node deformations in an arbitrary direction.
| |
| Ā | |
| ====Plate coordinate system====
| |
| The planar plane of the plate is the local XY-plane. If the plate is drawn clockwise then the Z-axe is positive.
| |
| Ā | |
| [[File:PlateCoordinateSystem.png|200px|none|]]
| |
| Ā | |
| The in- and output data will be displayed with regard to the above explained coordinate system.
| |
| Ā | |
| *A force in the direction of the positive x- or z- axis is considered positive.
| |
| *A moment rotating from the positive x-axis to the positive z-axis (according to the cork-screw rule) is positive.
| |
| *A moment opposite to the 'clockwise' rotation is positive.
| |
| Ā | |
| ===Input===
| |
| ====Navigation in 3D====
| |
| For navigating in your 3d model, 2 common methods are supported. You can set which one you want to use. Tab Settings & Manual > Settings > Navigate tab See Navigating
| |
| Ā | |
| 1. Method as in '''Autodesk Revit''' (default)
| |
| Ā | |
| * '''Zooming in and out'': Use the mouse wheel.
| |
| * '''Pan'': Press the mouse wheel and drag.
| |
| * '''Orbit'': Press the mouse wheel and '''SHIFT''' key together and drag.
| |
| Ā | |
| 2. Method as in '''Tekla structures'''
| |
| * '''Zoom in and out": Use the mouse wheel.
| |
| * '''Pan": Press the mouse wheel and drag.
| |
| * '''Orbit": Press the mouse wheel and '''CTRL''' key together and drag.
| |
| Ā | |
| XFEM4U also supports the use of a 3d mouse (from e.g. [https://3dconnexion.com/nl/spacemouse/ 3D Connection] ) which makes working even easier and faster.

| =====Beams=====
| |
| Ā | |
| ======Preface======
| |
| In the graphical screen beams can be added very easy by drawing them. Select this item in the function bar.
| |
| Beams are drawn as a 'polyline' just as you know it from AutoCAD.The begin node from a following beam is the end node of the last drawn beam.
| |
| Ā | |
| It is possible, but not necessary, to draw nodes before you insert the beams.
| |
| You can also start with drawing the beams, in this way the nodes will be inserted automatically.
| |
| Ā | |
| When you draw your first beam, the dialog box shown below appears. In this box you can, among other things, insert the beam connections and the profile of the beam. Use the escape-key or click the right mouse button to end the drawing of the beams.
| |
| Ā | |
| [[File:DocumentationXFEM4UBeam1.png | 500px]]
| |
| Ā | |
| As you are drawing a beam, help lines (horizontal and vertical) will appear connected to the previous inserted nodes. Often the node, to which you want to draw the beam, has the same x- or y- or z-value as the previous one. In this way it is easy to insert nodes. Obviously you can adapt the coordinates afterwards numerically or by moving the node.
| |
| Ā | |
|
| |
| While drawing a new beam, a dimension line parallel to the beam in one of the main directions x,y or z will appear. You can, just as you know it from AutoCad, immediately insert the distances numerically by entering the value / values from your keyboard. There are 3 possibilities for drawing a beam:
| |
| Ā | |
|
| |
| '''1. Drawing a beam with a known length in one of the main directions.'''
| |
| Ā | |
| The value will appear in the dimension line. Here you can type in the distance. By the use of the enter-key the input is closed and the beam with that length will be added.
| |
| Ā | |
| '''2. Drawing a beam using relative Cartesian coordinates (dx, dy, dz).'''
| |
| Ā | |
| First you enter the distance in x-direction. The value will appear in the dimension line. Thereafter you type a semicolon ";" and the distance in y-direction. The value will appear in a second input field. Next you type a semicolon ";" and the distance in z-direction. The value will appear in a third input field. By the use of the enter-key the input is closed and the beam is added.
| |
| Ā | |
| '''3. Input of relative cartesian coordinates (dx, dy, dz) or absolute cartesian coordinates (x, y, z).'''
| |
| Ā | |
| Press the space key and the dialog box below appears. Here you can enter relative coordinates or absolute coordinates directly.
| |
| Ā | |
| [[File:DocumentationXFEM4UBeam2.png | 300px]]
| |
| Ā | |
| In this way, you can quickly insert your construction.
| |
| Ā | |
| When you draw a beam for the first time, a profile needs to be chosen / inserted. There is asked what kind of profile you want to add. Also when you insert a new profile, there is asked which kind of profile you want to add.
| |
| Ā | |
| Subsequently the following dialog box of the profiles is shown. See [[Profiles]]
| |
| Ā | |
| [[File:DocumentationXFEM4UBeam3.png | 300px]]
| |
| Ā | |
| '''Changing a beam'''
| |
| Ā | |
| Changing a beam is possible by clicking on the beam with the left mouse button, and subsequently choose for properties by clicking with the right mouse button. There is a more easy way, namely a double click on the beam. Consequently the following dialog box will be opened.
| |
| Ā | |

| |
| Ā | |
| Ā | |
| '''Split into structural member sections for analysis'''
| |

| Setting whether, for the determination of the force distribution (framework calculation), the beam has to be split in in partial beams when nodes are found on the beam. This function is enabled by default.
| |
| Ā | |
| Ā | |

| |
| Ā | |
| [[File:DocumentationXFEM4UBeam3.png | 300px]]
| |
| Ā | |
| '''Tapered beam'''
| |
| Ā | |
| You can optionally enter a tapered beam (Non-prismatic beam). The tab "Profile end" is activated. Here you can enter the 2nd profile at the end of the beam. Attention! The basic shape of the profile section (H-, U-, L-shape, etc.) must match that of the profile at the beginning of the beam.
| |
| Ā | |
| For calculation background. See [[Tapered beam]]
| |
| Ā | |

| |
| Ā | |
| With this the profile is orientated relative to the schematic line. ( The schematic line is the line from the begin node to the end node)
| |
| z is the distance in the local z-direction between the schematic line and the reference line of the profile. The reference line of the profile is showed in the middle by default, but can be set at the top, middle or bottom.
| |
| Ā | |
|
| |
| '''Torsion reduction'''
| |
| Ā | |
| Percentage by which the torsion stiffness of the beam is reduced. Specifically for concrete beam grids, it is allowed to reduce the torsion stiffness in case of compatibility torsion. Thereby the occurring torsion moment is lower, and less torsion reinforcement is needed. (stirrups and longitudinal reinforcement)
| |
| Ā | |
| Ā | |
| '''Beam connection begin and end'''
| |
| Ā | |
| Here you enter how the beam is connected at the begin node and at the end node. There are multiple options.
| |
| Ā | |
| You can make use of the most common / standard connections:
| |
| Ā | |
|
| |
| '''Fully fixed'''
| |
| Ā | |
| Tx=A(Absolute), Ty=A, Tz=A, Rx=A, Ry=A, Rz=A. (That is the standard setting)
| |
| Ā | |
| Ā | |
| '''Hinge'''
| |
| Ā | |
| Tx=A, Ty=A, Tz=A. There is no transfer possible between moments, only shear force and normal force.
| |
| Ā | |
| Ā | |
| '''Tension only'''
| |
| Ā | |
| This works the same as a hinge support, the only difference is that tensile forces (positive normal forces) can be transferred.
| |
| Ā | |
| Ā | |
| '''Springer connection'''
| |
| Ā | |
| You can also add a beam with a springer connection. Tx=S(Spring), Ry=S en/of Rz=S. You also need to insert the spring constantĀ Kx, Cy and/or CzĀ in kN/m resp. kNm/rad
| |
| Ā | |
| Ā | |
| '''Input per beam'''
| |
| Ā | |
| This gives you the possibility to adapt the input for every new beam.
| |
| Ā | |
| ======Beamproperties: Eurocode======
| |
| Ā | |
| [[File:DocumentationXFEM4UBeam6.png | 500px]]
| |
| Ā | |
| '''EN 1993-1-1 / EN 1995-1-1'''
| |
| Ā | |
| Specifically and only for the check according to Eurocode 3: EN 1993-1-1 respectively Eurocode 5: NEN-EN 1995-1-1data can be inserted.
| |
| Ā | |
| Ā | |
| '''Beam group'''
| |
| Ā | |
| Specifically and only for the lateral-torsional buckling resistance check a beam group can be inserted here. XFEM4U automatically detects for which beams this qualifies. Only the beams which are connected by a fully fixed connection to this particular beam and have the same profile will be showed. You can select which beams should be taken into account. For this group you subsequently enter the length between the lateral restraints and the buckling length out of plane.
| |
| Ā | |
| Ā | |
| '''Lateral torsional buckling'''
| |
| Ā | |
| Amount of lateral supports / distances between lateral supports
| |
| Ā | |
| This is only relevant for the check of lateral torsional buckling. You can enter the lateral supports for the top and the bottom flange.
| |
| Ā | |
| Ā | |
| There are 3 options:
| |
| Ā | |
| '''1. Number''': The amount of lateral supports. That are the extra (lateral supports) between the supports distributed over the length of the beam(group)
| |
| Ā
| |
| Ā | |
| '''2. Distances''': The lengths between the lateral restraints from the beginning of the beam (group). The syntax is ''length1 length2 amountxlenght3.. etc''.
| |
| For example 3000 3x2200 2800
| |
| Ā
| |
| Ā | |
| '''3. Node numbers''': Selecting the node numbers which are in the beam group.Ā
| |
| Ā | |
| Ā | |
| '''Buckling lengths Y-axis and Z-axis'''
| |
| Ā | |
| The check according to Eurocode 3: EN 1993-1-1 is based on a geometric non linear force distribution. This means that the buckling of the beams in the plane of the frameworks is provided implicit in the force distribution. For every load combination the internal stability is determined iteratively. By default the buckling length around the y-axis is equal to the beam length. The buckling length around the z-axis is equal to the biggest lateral torsional buckling length. You can also enter different values for both the buckling lengths. See also [[Buckling]].
| |
| Ā | |
| Ā | |
| '''Note:''' Regardless of whether the profile is rotated with respect to the local coordinate system, the Y axis is the strong axis and the Z axis is the weak axis analogous to the Eurocode. (See below.) In all checks, all beam forces are transformed to this coordinate system.
| |
| Ā | |

| |
| Ā | |
| The size of pre-camber in mm.
| |
| Ā | |
| ======Beamproperties: Dummy======
| |
| Ā | |
| Specifically for plates,Ā it is possible to enter dummy beams. Arithmetically, a dummy beam is taken into account with small bending stiffness.
| |
| Ā | |
| Ā | |
| '''Line Loads''': With dummy beams, any line loads on a plate can be taken into account.
| |
| Ā | |
| '''Line supports''': Dummy beams can be supported by.

| =====Slabs/Plates=====
| |
| Ā | |
| ======General======
| |
| Ā | |
| In the graphical screen slabs can be added very easy by drawing them. Select this item in the function bar.
| |
| [[File:Plates 32.png|32 px|Wikipedia encyclopedia]]
| |
| Ā | |
| Plate egdes are drawn as a 'polyline' just as you know it from AutoCAD.The begin node from a following beam is the end node of the last drawn plate edge.
| |
| Ā | |
| It is possible, but not necessary, to draw nodes before you insert the plates.
| |
| Ā | |
| You can also start with drawing the plate edges, in this way the nodes will be inserted automatically.
| |
| Ā | |
| When you draw your first plate edge, the dialog box shown below appears. In this box you can, among other things, insert the material data of the slab. Use the escape-key or click the right mouse button to end the drawing of the plate edges.
| |
| Ā | |
| As you are drawing a plate edge, help lines (horizontal and vertical) will appear connected to the previous inserted nodes. Often the node, to which you want to draw the beam, has the same x- or y- or z-value as the previous one. In this way it is easy to insert nodes. Obviously you can adapt the coordinates afterwards numerically or by moving the node.
| |
| Ā | |
| While drawing a new plate edge, a dimension line parallel to the plate edge in one of the main directions x,y or z will appear. You can, just as you know it from AutoCad, immediately insert the distances numerically by entering the value / values from your keyboard. There are 3 possibilities for drawing a plate edge:
| |
| Ā | |
| Ā | |
| '''1. Drawing a plate edge with a known length in one of the main directions.'''
| |
| Ā | |
| The value will appear in the dimension line. Here you can type in the distance. By the use of the enter-key the input is closed and the plate edge with that length will be added.
| |
| Ā | |
| Ā | |
| '''2. Drawing a plate edge using relative Cartesian coordinates (dx, dy, dz).'''
| |
| Ā | |
| First you enter the distance in x-direction. The value will appear in the dimension line. Thereafter you type a semicolon ";" and the distance in y-direction. The value will appear in a second input field. Next you type a semicolon ";" and the distance in z-direction. The value will appear in a third input field. By the use of the enter-key the input is closed and the plate edge is added.
| |
| Ā | |
|
| |
| '''3. Input of relative cartesian coordinates (dx, dy, dz) or absolute cartesian coordinates (x, y, z).'''
| |
| Ā | |
| Press the space key and the dialog box below appears. Here you can enter relative coordinates or absolute coordinates directly.
| |
| Ā | |
| Ā | |
| [[File:Slapes and plates.png|250 px|Wikipedia encyclopedia]]
| |
| Ā | |
| In this way, you can quickly insert your slab/plate.
| |
| Ā | |
| The plate can be supported in different ways. By Nodes and/or Plate edge.
| |
| Ā | |
| You can enter Plate loads and/or Node loads.

| =====Nodes=====
| |
|
| |
| Nodes can easily be added in the graphical screen. To do this, you have to choose [[File:Cur node.png|28 px|Wikipedia encyclopedia]] in the menu bar. In these modus you can add multiple nodes by means of the left mouse button. By placing the node, you will see the coordinates in the right bottom. As is shown in this image below.
| |
| Ā | |
| [[File:Shown in this image below. node2.png|600 px|Wikipedia encyclopedia]]
| |
| Ā | |
| Nodes can be added arbitrary in a fixed raster or at grid lines.
| |
| Ā | |
| Supports are nodes which are restrained in a certain direction.
| |
| Ā | |
| Ā | |
| '''Changing a node'''
| |
| Ā | |
| Changing a node is possible by clicking on the node by use of the left mouse button, and subsequently choose for properties by clicking on the right button. There is a more easy way, namely a double click on the node. Consequently the following dialog box will be opened.

| |
| Ā | |
| [[File:Support.png|100 px|Wikipedia encyclopedia]]
| |
| Ā | |
|
| |
| '''Eccentricities'''
| |
| Ā | |
| Only for supports ( nodes with restrictions / restraints in a certain direction) you can add a eccentricity by inserting 3 relative coordinates dx, dy and dz. An extra node and a 'stiff' beam are automatically generated. Hereby you can, for example, in the calculation of a concrete beam grid, take the misplacement of a pile into account. The foundation beams can subsequently be tested for torsion and extra bending.

| In '''XFEM4U''' it is possible to use a standard grid with grid lines. A standard raster is created, but you can adapt this raster.
| |
| Ā | |
| Beams and nodes can be easily drawn into the grid. '''XFEM4U''' has a magnet function, which snaps to points into the grid.

|
| |
| Ā | |
| '''Coordinates'''
| |
| Ā | |
| You can define the grid lines yourself.
| |
| Ā | |
| Syntax: ''' ''distance spacing1 amount x spacing.. etc'' '''
| |
| Ā | |
| Example:''' "0 3000 3x2200 2800".'''
| |
| Ā | |
|
| |
| For the z - coordinate, if you enter the numbers with a +, then you are entering absolute values.

| ======Internal hinge in a beam======
| |
| Ā | |
| Adding an internal hinge in the graphical screen is very easy.
| |
| Ā | |
| Choose for the following image in the menu bar.cur_InternalHinge. [[File:cur_InternalHinge. .png|28 px|Wikipedia encyclopedia]]
| |
| Ā | |
| Ā | |
| In these modus you can add multiple internal hinges by use of the left mouse button. By placing the hinge, the coordinates are shown in the right bottom.
| |
| Ā | |
| Ā | |
| When you add an internal hinge, a new node in the beam is generated, and the regarding beam is automatically divided into two beams with a hinge connection. The beam loads also will be adjusted automatically.
| |
| Ā | |
| Ā | |
| In this way you can easily design a gerber beam.

| '''Type'''
| |
| Ā | |
| The type of load. Dependent on the type of load, standard combination factors (frequent / quasi-permanent value ) psi0, psi1, and psi2 are determined according to the Eurocode.
| |
| Ā | |
| These combination factors are offered as a standard by entering the load combinations. However, these values can be adapted.
| |
| Ā | |
| Automatically two load combinations are generated. Permanent and variable loads.
| |
| Ā | |
| Ā | |
| '''Automatically generate combinations'''
| |
| Ā | |
| When you enter/change load combinations, the load combinations are automatically generated. You can also change these combinations and expand them.
| |
| Ā | |
|
| |
| '''Permanent load favorable'''
| |
| Ā | |
| Extra ULS load combinations are generated in which the load factor for the permanent load is 0.90.
