Hi there,
I have a deformed beam (I moved the nodes to simulate an imperfection) and when I run a second order P-delta analysis I get the exact same results as in a first order analysis.
I've attached my simple model for your convenience.
Thanks
Tiago
Results are not exactly the same .
Maybe due to the small applied vertical load

Hi Rafa, Thanks for your reply.
I'm expecting an increase of 1/(alfa,crit-1) not some really residual differences when I have such low alfa crits.
Cheers
Tiago
