| ===Coordinate System=== | | ===Chapters user manual=== |
| Β | | [[Get started with the Struct4U Engineering Tools | 1. Get Started]] |
| The program knows four '''clockwise''' coordinate systems.
| |
| Β | |
| ====Main coordinate system====
| |
| Β | |
| 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.
| |
| Β | |
| [[File:MainCoordinates.png|200px|none|]] | |
| Β | |
| ====Beam coordinate system====
| |
| Β | |
| 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.
| |
| Β | |
| [[File:BeamCoordinates.png|200px|none|]]
| |
| Β | |
| ====Node coordinate system====
| |
| Β | |
| [[File:NodeCoordinate.png|200px|none|]]
| |
| Β | |
| 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.
| |
| Β | |
| ====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.
| |
| Β | |
| [[File:PlateCoordinateSystem.png|200px|none|]]
| |
| Β | |
| The in- and output data will be displayed with regard to the above explained coordinate system.
| |
| Β | |
| *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.
| |
| Β | |
| ===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
| |
| Β | |
| 1. Method as in '''Autodesk Revit''' (default) | |
| Β | |
| * '''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.
| |
| Β | |
| 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.
| |
| Β | |
| 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=====
| |
| Β | |
| ======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.
| |
| Β | |
| 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.
| |
| Β | |
| 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.
| |
| Β | |
| [[File:DocumentationXFEM4UBeam1.png | 500px]]
| |
| Β | |
| 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.
| |
| Β | |
|
| |
| 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:
| |
| Β | |
|
| |
| '''1. Drawing a beam with a known length in one of the main directions.'''
| |
| Β | |
| 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.
| |
| Β | |
| '''2. Drawing a beam using relative Cartesian coordinates (dx, dy, dz).'''
| |
| Β | |
| 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.
| |
| Β | |
| '''3. Input of relative cartesian coordinates (dx, dy, dz) or absolute cartesian coordinates (x, y, z).'''
| |
| Β | |
| Press the space key and the dialog box below appears. Here you can enter relative coordinates or absolute coordinates directly.
| |
| Β | |
| [[File:DocumentationXFEM4UBeam2.png | 300px]]
| |
| Β | |
| In this way, you can quickly insert your construction.
| |
| Β | |
| 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.
| |
| Β | |
| Subsequently the following dialog box of the profiles is shown. See Profiles
| |
| Β | |
| [[File:DocumentationXFEM4UBeam3.png | 300px]]
| |
| Β | |
| '''Changing a beam'''
| |
| Β | |
| 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.

|
| 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)
