Seismic Loading

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

  • Hi,

    Thank you for your mail below.

    I do not know what happened to my attachment since it was with the mail when I sent it.

    I looked at the information in your previous mail but all I could see was an issue with STAAD crashing all of the time.

    However, the good news for me is that (for some reason) the ICONS have returned - but I do not know how or why!!!

    I guess therefore that my problem is solved.

    Thanks again and kind regards,

    Keith
