It is the analysis of slabs by dividing them into shell elements and taking into account their deformations.
With Semi-Rigid Diaphragm Behavior;
-
Slabs are divided into shell elements.
-
Since the in-plane effects of the slab are taken into account, it gives more precise results.
-
Story masses are considered as distributed masses along the slabs.
Preferred building types;
-
Structures with plan irregularity and torsional irregularity
-
Structures with slab discontinuity
-
Structures with beamless slab system
-
Structures with rib or cassette slab system
The slab is divided into shell elements and deformations are taken into account.
-
When we compare the rigid diaphragm and semi-rigid diaphragm models, different displacement values are seen in the middle region of the models.
-
In the semi-rigid diaphragm model, the displacement value is 0.163 millimeters.

Diaphragm Modeling Selection
To model a Semi-Rigid diaphragm, select the diaphragm modeling method from the Analysis Settings dialog.
