leaning column for PDelta effect

[a.salmanpour]

Hi
I want to model a frame with a leaning column for P Delta effect. Which type has
less converge problem, 1- use equal dof 2- use rigid link or 3- use a very stiff elastic truss element?
if I use equal DOF, Can I use RCM numberer?


Thanks

all very good questions, i think the equaldof command might work better.
i am just going to get to this problem, so if anyone has insight, it'd be great.

Hi...
What is the suitable method of defining Leaning column?
Element with end pin connections?
And the same questions as the 1st post!
