Rigid Diaphragm Conditions (4.5.6.3)
The analysis model of the slabs modeled by selecting the fully rigid diaphragm is created automatically.
If there is no A2 and A3 type irregularity, the floors can be modeled as a fully rigid diaphragm. In analysis settings Rigid, Semi-Rigid, and Flexible Diaphragm Types selection can be made upon request.
While considering the additional eccentricity effect as required by 4.5.10 , a fully rigid diaphragm model is installed automatically in accordance with the regulation independent of the diaphragm selection.
