Rigid diaphragm

[HoshangMustafa]

Hi

Am I right:

1- Rigid diaphragm will transfer the load on panel directly to the beams without contributing to the bending moment induced due to the applied vertical load on the surface of the panel.

2- Rigid diaphragm will result in max My and Fz in the beams supporting the panel.

3- If I model panel with rigid diaphragm the design of the beams will be safer.

Correct as there is no surface elements generated.

2- Rigid diaphragm will result in max My and Fz in the beams supporting the panel.

If you mean that the load distribution generated in this way will create bending and shear in the beams then yes.

3- If I model panel with rigid diaphragm the design of the beams will be safer.

I can't tell. In the situation when the load distribution is different than based on tributary area this may not be true.
