In a Dynamic Analysis when defining a seismic load cases and using the command "SPECTRUM" does one use the site specific "Seismic Response Coefficient" Cs based on S1 and Ss accelerations derived from ASCE 7?
For example, if I calculated a Cs = 0.065…
For those of you who don't have the ASCE 7-05 handy, this special seismic provision basically says that cantilever beams should be designed for a minimum net upward force of 0.2 times the dead load.
We don't automate this in RAM SS right now. We do…
The Loads and Applied forces report is the most detailed one we have. Based on your values above, it looks like you might be in Seismic Design Category A, where the simplified method kicks in and CS is just 0.01.
