Can someone please give me the STAAD input text for seismic to UBC and to BS EN 1998 - I find the STAAD help editor difficult to follow.
I am assuming that I will use CQC for the modal analysis, but what about SRSS etc.
In the example I have pulled together, I get 85% mass participation after 6 modes - how do I increase the number of modes in order to raise the mass participation to what I think I need of around 97%
Thanks
