Hi everybody,
I'm working with a FEM software.
I'd like to know the procedure to performe a modal response spectrum analysis of a 3story building.
I've already modelled the structure and calculated the design spectrum.
Thanks for any help!

One approach is to synthesize a time history to satisfy the shock response spectrum.
Then use the time history as a base input to modal transient analysis.
