precast flooring in etabs

(OP)
Is there anybody knows how to model precast flooring(hollowcore) in ETABS?

RE: precast flooring in etabs

Model them as membrane elements (i.e. no out of plane bending capacity).

thanks slickdeals, but how you will take into account the hollowcore and thickness of the precast floors?

RE: precast flooring in etabs

The hollowcore supplier will have the weights of the hollowcore panels. You can specify a equivalent solid thickness of concrete to account for the weight. For example, if it weights 100 psf, use 8" slab.

You are not going to use this model to design the hollowcore slab. You will use this only to get the forces/moments for the design of supporting precast beams/walls.
