Flexible Diaphragms

Flexible Diaphragms

(OP)
hi folks, i´d llike to know how can i modelate a flexible floor  concrete diaphragm in ETABS

RE: Flexible Diaphragms

AS far as I know, you just need to create a shell property in "Define" "Wall/Slab/ sections"

The shell element should have the appropiate material properties and thickness

hope this can help


RE: Flexible Diaphragms

In a change from previous versions, from V7 ahead, flexible diaphragms are the default in ETABS.  If you desire a rigid diaphragm you have to define it explicitly.  So, essentially, if you do nothing you will end up with a "flexible" floor diaphragm.
