STAAD Pro - Rigid Diaphragm

STAAD Pro - Rigid Diaphragm

STAAD Pro - Rigid Diaphragm

(OP)
I have a structure composed of steel members (one story high) and on top a concrete slab (metal deck). There are expansion joins at various locations.

How do I go about modeling this on STAAD? I just want to model the steel, but I need to have it as a rigid diaphragm. I had no luck with using floor plates or master/slave.

Has anyone had success doing this?

RE: STAAD Pro - Rigid Diaphragm

If you just want to model the steel but want to account for the inplane rigidity due to the diaphragm, you can either use master slave ( SLAVE ZX ) OR use the floor diaphragm option ( introduced from 20.07.08.xx onwards ). Not sure what issues you faced with master slave. If you can send the specific details with your model, I can take a look.

RE: STAAD Pro - Rigid Diaphragm

(OP)
Well I have an expansion joint on the same floor (shared nodes in one row) so I cannot properly do the master slave command since there is common nodes.

I haven't used the Floor Diaphragm command, not sure how to specify it.
