push-over doubts

[chiaramgn]

Dear Seismo,
I need to do a pushover analysis of a R.C. arch bridge. My question is, to do a pushover analysis with horizontal load proporzional to masses, there is not a way to do it without putting incremental loads? Because I need that the loads automatically are disposed proporzional to masses (external and of the same bridge). Thanks, Chiara

Dear chiaragn,

You should apply icremental loads in order to run a pushover analysis. For more information you may refer to SeismoStruct User Manual and Help System.
