When modeling floors, the "Semi-rigid diaphragm" option is available for slabs.
In principle, this modeling option selects the same approach as for the "Rigid Diaphragm" floor modeling. In contrast to the rigid diaphragm, no nodal coupling is carried out from the center of gravity to each FE node. In this way, the flexibility of the ceiling can be taken into account.

When generating shear walls and deep beams, you can assign not only surfaces and cells, but also members.
You can neglect openings with a certain area in the building model calculation. This function can be activated in the global settings of the building stories. A warning message appears saying that the openings have been neglected.
The building model is calculated in two phases:
After the calculation, the results of the columns and walls from the 3D calculation and the results of the slabs from the 2D calculation are combined in a single model. This means that there is no need to switch between the 3D model and the individual 2D models of the slabs. The user only works with one model, saves valuable time, and avoids possible errors in the manual data exchange between the 3D model and the individual 2D ceiling models.
The vertical surfaces in the model can be divided into shear walls and opening lintels. The program automatically generates internal result members from these wall objects, so they can be designed as members according to any standard in the Concrete Design add-on.
