Hi! I have a problem me too with displacement-adaptive pushover. At each analysis step t I calculate the target displacement of every floor from a relation : U(t)=U(t-1)+λ*D(t), where U(t-1) is the displacement of the previous step, D(t) is a displacement vector that I calculate from eigenvalue anal...

Thanks a lot!!

Hi everyone! I'm quite a new user of Opensees, I'm using it to run some pushover analyses for my diploma thesis. Please!!I need some help!I want to run a force-adaptive pushover analysis, I mean I want to perform eigenvalue analysis at each step of the pushover. How can I program it?
