Slab / Stairs
-
For slabs, an additional function has been developed to account for shape orthotropy.
In the dialog box, the user can select the type of structural slab form and specify the necessary geometric parameters to determine its reduced stiffness and calculation behavior.
The following options are supported:
- one-way ribs in one direction;
- two-way ribs in one direction;
- one-way ribs in two directions;
- one-way box slab;
- two-way box slab;
- beam grillage;
- corrugated decking;
- wavy corrugated decking;
- slab on corrugated decking;
- hollow-core slab with circular or oval voids;
- solid slab.
Setting input data for shape orthotropy
- Added the option to select self-weight loading for inclined slabs and stairs.
- Added an alternative method for editing an inclined slab with free top and bottom binding.
- Improved load generation from spaces for inclined slabs.
