Note: Suggest to perform "AutoPIPE MSRS Example Tutorial" 

With AutoPIPE open, select Help> Contents> Contents Tab> Supplemental Documentation> select the document "Supplemental Documentation"  scroll down to "AutoPIPE MSRS Example1". Highly recommended to actually perform example using model mentioned in aforementioned document. This will give the user a good foundation on what it takes to perform a Response Spectrum.

Comments, Questions, and Answers

Item #0: Insert Dynamic Seismic / Response spectrum load case

Item #1: Under the Missing Mass Combination drop down listing in a model, only the SRSS and Absolute SUM method appear as choices. Where is Modal?

Item #2: Why do the acceleration values need to be multiplied by 25.4 ?

Item #3: Should ZPA be applied when performing a Dynamic analysis?

Item #4: Is there more information available on modal analysis?

Item #5: Multiple support response spectra (MSRS) and the uniform response spectrum analysis results are different
