Thank u for your reply,Amin Asareh. I built the pile model just as the method you say.Now i wanna kown the reason why the pile itself can not reach ultimate state. As u know,the pile section is built with fiber section,in my opinion,the pushover analysis will be failure convergence when the maximum ...

hello,everybody.I did pushover analysis to a single pile which use fiber element and model soil-pile interaction by p-y curves.And lateral load pattern is concentrating horizontal load at top of pile.Displacement control method is used in analysis.I find out that the maximum curvature of pile sectio...

thanks your detailed explanation ,i will try your method.

i just built a simple one degree freedom cantilever column which use fiber section,the column is 20m high.then i perform a static analysis.at the end when the pushover curve which is relationship of base shear and control piont displacement is ploted,i find the curve without degressive segment,so i ...
