Hi, I applied seismic load in SA

Hi,

I applied seismic load in SAP2000 using the Response Spectrum procedure.
I am getting zero reactions and forces in the members.
Not sure how to fix this issue.

Problems could be many. Some things to check:
How is your mass source defined for the modal analysis?
What are the modal analysis settings? Response spectrum analysis settings?
What load combinations include the response spectrum results? Have you confirmed that your current run is including those load combinations?
