Slab Punching and Deflection


I’m modeling a residance concrete building without beams, when using Optimize Cross Section does the calacutaion takes in considiration slab punching? If so what is the best way to define capital in karamba?

One more thing i was wondering about does the reasults show immediate deflection or long term deflection?

Thanks you :slight_smile:

Hi Yoav,

the ‘Optimize Cross Sections’ does not take into account slab punching. This is something which needs to be checked manually or via a script in another step.

The results show the short term behavior of uncracked concrete. Depending on the environmental conditions one has to multiply the resulting displacements by a factor of roughly five for cracked concrete and long term deflection.


Hi Clemens,

Got it, thank you for the fast response.
