Response Spectrum Analysis with Multiple Spectrum Curves

Response Spectrum Analysis with Multiple Spectrum Curves

Response Spectrum Analysis with Multiple Spectrum Curves

(OP)
In SAP2000, is it possible to perform a Response Spectrum Analysis with multiple spectrum curves ? I created 2 spectrum functions, one from code based design spectrum and next a spectrum generated from a ground motion. Then I created a Response Spectrum load case and added these two functions. The analysis is always performed for the first defined function.

Is it possible to add two functions for a single response spectrum analysis ?

Thanks

RE: Response Spectrum Analysis with Multiple Spectrum Curves

So within the same response spectrum load case you had two lines of Acceleration loads each with different RS functions? Each line should use its own specified RS function and its own scale factor. If that's not what happened then attach your .sdb file
