mass participation in modal analysis

[kgkoktsi]

Dear all,
does anybody know if I can get an output file with the mass that is activated in each mode in a modal analysis?
Thanks in advance!

No, there is no such recorder in OpenSees, but if you need that info you can write a procedure that will calculate it for you.

Thank you vesna!
Is there any script available so as to give me any idea of the procedure you are talking about?
Once again, thank you!

I do not have a procedure file you need but I think someone has posted something useful on the message board. Search the message board.
