thanks for your help but I know of that movie,
it does not give any details of the analysis procedure.
what I d like to learn are the essence of the Pushover
and how you d perform for a simple RC structure, issues
related with modeling the steel bars in the elements etc.
Well there is a presentation at johnmartin.com and also I have a brief PDF on pushover by csi-berkeley, drop me your email if you'd like to see it. Other than that, perhaps google is the best shot. (I'm also trying to figure out pushover).
