Is it possible to design a waffle slab in Robot?
I imported a waffle slab that I had created in Revit Structure using structural framing with joists and a thin concrete slab over it, but I received many rebar error messages. Is there a better way?
Thanks

During design process program uses homogenous panel thickness although it may be defined in ARSA as orthotropic one.
I guess (without looking at model) this error messages comes from geometrical limitations for bar distributions. PLease check \ set covers, layers etc.
So to be more precise we need the model file to look at.
Dear Rafal,
do you have any example of a waffle slab? I use in the majority of my projects a 80x80x28 cm waffle slab. Where 80x80 is the distance between the joist beams. The concrete cap is 8 cm (already included in the 28cm). The size os the joist is 12,5 cm on the bottom and 15,6cm on the top. What is your suggestion: should I model in Revit or directly in Robot as a orthotropic one?
Look below. We may also try other types of orthotropy.
If you want to design also beams under the plate I suggest to define slab as homogenenous and create "real grillage" of beams underneath.
Thank you Rafal, I believe that the best solution is to define the slab as homegeneous and create beams underneath. Gustavo
