Good morning / Good evening ;
I would like to know how to access the flag indication the use or not of a residual mode for a given seismic case by using API.
and by the way , auxilliary data ( Last calculated mode , limite frequency , augmentation factor )
Thank you

This option is currently not available in API. I have added it to the wish list.

Hello,
I have made a modal analysis for a five story reinforced concrete building based on the UBC97 code
The mass participation for X & Y directions is about 73% and the frequency is about 33 (no significant change in these results from mode number 30 to mode number 40)
I have read that for such case residual mode should be used for seismic analysis, I have tried but I did not know how to do it
Thank you for help
Hi,
It seems, this feature is not RSA for UBC 97
Window for EC8 regulation
Window for UBC 97

Okay, any idea what to do in such a case as I mentioned (mass participation 73 and frequency 33)

You should use the spectral analysis you can define there the spectrum as per UBC then include residual mode.
