Waffle Slabs in Etabs

Waffle Slabs in Etabs

Waffle Slabs in Etabs

(OP)
I need to model a structure with waffle slabs. The structure is very irregular and using the template for waffles slabs (i.e. new model, waffle or Edit add to model) will probably do nothing good. Any idea of approximations or tips of how to build the model. It's a 14 story building. If I use waffle slabs template it'll make the model very difficult to work with. Will take great time computer wise for the design.
Any ideas are highly appreciated.

Try to build a 3D model in Cad and then make a DXF file, which one you can import in to Etabs. I follow this way and it's working. You can also try with Revit...

RE: Waffle Slabs in Etabs

Are you going to design the waffle slab using ETABS ?

I doubt if it does that. You can put the self weight to zero for a regular slab, and put equivalent SDL on the slab enements for reaction purposes.

Also, you need to provide cracking MOI -"Icr" for deflection purposes.

I hope that helps.
