GGU-SLAB: "Circular slab, …" menu item
This menu item makes it simple to define circular slabs and the FEM mesh. It is then possible to select different slabs:
"Circular slab (simple)"
Create a simple circular slab by means of the diameter, number of rings and segments. A displacement of "0" can be defined at the outer edge. Dimensioning can also be activated in the dialog box. Force and moments can be applied in the slab centre or as distributed loads on a selected ring. The moments can be adopted to calculate the torsional stiffness.
Any existing nodes and FEM mesh are automatically deleted. When you leave the dialog box the program recalculates the coordinates and displays the newly generated circular slab on the screen with the optimum coordinates."Circular slab (pro)"
You can generate a more complex circular slab.
"Annular slab"
An annular slab can be generated via the number of rings and the internal and external diameters. A displacement of "0" can be defined at the inner and/or outer edges. Force and moments can be applied in the slab centre or as distributed loads on a selected ring. The moments can be adopted to calculate the torsional stiffness."Annular slab (pro)"
You can generate a more complex annular slab."Elliptical slab"
An elliptical slab can be generated. Simply define the diameters in the x and y directions. A displacement of "0" can be defined in slab centre and/or at the outer edge. Dimensioning can also be activated in the dialog box."Distributed loads from M+V"
The distributed loads can be calculated from M and V by the program. The moments can be adopted to calculate the torsional stiffness.
The data specified in the message box are then calculated and displayed. They can be copied to the Windows clipboard by pressing "Copy data to clipboard". If the distributed loads are then determined the minimum and maximum stresses are displayed in a message box. After exiting the box by pressing "OK" the distributed loads are generated for the entire FEM mesh.
