Hi,
Is it possible to manually set omega and rho factor in seismic calculation in Robot?
I have found some options in csi etabs and attached the snapshot.
Do you think there is any similar option in Robot? Are these factors automatically calculated by Robot? If so where can I check their value?

NO, Robot does not use omega and rho factors fro seismic calculation for IBC code. These factors are used in case of simplified analysis procedure IBC 2003 Section 1671.5.
Robot calculates seismic load with dynamic spectral analysis.
