I am using Leap Concrete Version 18.02.02.03 for a multi column pier design that includes seismic forces. I need to apply a response modification factor for the columns and the help guide states that this can be modified in the Seismic Parameters. However, there is no section for response modification factors in the Seismic Parameters tab.
Any ideas on how to update the response modification factor for column seismic design?
Here is the screen when I select Seismic Design Parameters
Obviously this is too late to help, but maybe someone else has a similar question. It is possible to enter the Response Modification Factor if you are doing Single Mode Analysis (my bridge is in zone 2). It shows up in the Auto-Genration Input at the bottom left. I have been setting up 2 different files - one for cap and column (using R) and one for the footings & piles (using R/2).
I have not seen a place to enter it for the Multi-mode analysis.
Update - For multimode analysis, I have been able to modify the multipliers within the Extreme Event load combinations (1/R*EQ instead of 1.00*EQ). This is the only way I have found so far to apply the R factor.
