nonlinear analysis of slab

[AMRMASOUD]

We very need that SesimoStruct take into consideration the effect of nonlinearity of concrete slab , it is very needed & important for some case in seismic & progressive collapse.

Unfortunately, SeismoStruct 2020 does not feature a nonlinear slab element. What you could do is to use the beam section types (rcars or rcts sections) with a small depth to simulate the slab.
