I use SAP2000 for floor vibrations analysis. Does anybody know how to get a frequency-response plot from SAP? I've worked on this a while and don't see any way to do it other than pulling out an acceleration trace and doing a FFT or DFT in Mathematica, Matlab, Mathcad, or Excel. While not terribly difficult, it seems like a program like SAP would be able to do this automatically.

Will Ansys or Abaqus do this automatically?

I asked the question over in the SAP forum but heard nothing but crickets.

Any help greatly appreciated.
