FORM analysis

Post by mohamvasef » Fri Jun 29, 2018 12:33 am

I have a problem with running a FORM analysis for my bridge structure. When I run FORM analysis, it says "all components of gradient vector are zero". I have linked the OpenSees with RT to run the FORM analysis. FORM uses the drift output of timehistory analysis to compute the probability of failure.

I need your help. I dont know what is the problem :(
