Hi,
can anyone tell me is it possible to do modal analysis and seismic calculation with hollow slabs in construction model?
Thank you very much.

Thank you for your answer. I've already defined hollow slab in my model but during analysis error 902 appears. After that I changed the slab into homogeneous (just for check) and no errors showed, calculation was fine. I thought maybe self weight of hollow slab is not converted to masses?!
Error description :
902 |
Negative eigenvalue has been obtained |
PLease send me model to check
Here is the model. (Original model is too big to send so I made a little example)
Thank you.

Ivana,
Take a look below. You have defined wrong geometrical properoes of holes in holow slab.
Opening bottom edge is 2mm below slab bottom layer
ho/2 = 160 and hc=158 -> ho must be less or eq to 316
