I want to eliminate uplift force, but when I have seismic forces I can't define nonlinear case.
What can I do now? I have attached robot file and screen shots.
Could you please help me?

But I used equivalent lateral force so there isn't need to use modal analysis and modal results combination.
Seismic force in this way is constant and I defined it manually.
I think it's one of disadvantages of robot.
Is there any option to solve nonlinear calculations (not nonlinear analysis) with equivalent lateral seismic force?
You are correct yet due to some restrictions in Robot internal architecture this is currently not possible. We have this in mind for the next releases.
