Hi!
I have some more questions...
When we are performing a modal analysis (and then seismic) we asume that the slab is absolutely rigid for flexure.
So my q's are:
How do we model this in ETABS?
Do we model the slab as shell and then assign the rigid diaphragm option? or
Do we model the slab as membrane?
Another q is about modeling the slab as membrane:
I performed an analysis and still had bending in the slab. How can this be and what have i done wrong (if i did ;P )?
Tnx in advance
