This example will consist in the analysis of a simple concrete building introducing the concepts of combined load cases and the concept of concrete dimensioning.
The first step is to create the geometry. It can be defined using the GiD preprocessing commands described in the GiD manual. The following commands can be useful:
Geometry->Create->Line
Utilities->Copy->Translation (Do extrude lines)
Geometry->Create->NURBS surface->By contour
View->Rotate->Trackball (or pressing right button mouse in the GUI)
View->Render->Smooth
The final model will be composed of 8 surfaces, 22 lines for the supports, 28 lines for the boundary beams, 8 interior help lines (not meshed) and all of its connecting . Be careful to position the structure related to the global axes as seen in the picture. Then, it will be easier to follow the example. The six points that define the base projection of the building are the following:
A | -5,0,0 |
B | 12,0,0 |
C | 12,5,0 |
D | 5,5,0 |
E | 5,11,0 |
F | -5,11,0 |
As a convenience, it is interesting to subdivide the geometrical entities into several layers. This will help to assign the properties and to visualize easily the results. The chosen layers could be:
To transfer geometrical entities to one layer, use button entities in the layers window.
After creating the geometry, the GiD window will be similar to this one:
