Dear vesna,
How can one capture the effects of Global p-delta effects? and which of the two transform methods (namely Pdelta or corotational) is better for capturing geometrical effects while analyzing 3-D building frames with concentrate plasticity?
Thanks

hello ...
Regarding the P-delta effects, is it true to connect CM of each story in a 3D problem to a leaning column via an axially rigid element in both longitudinal directions to capture the P-delta effects or I need to define such columns for all frames in both directions?
Thanks,

Dear fmk
Thanks for your reply. There is just one question, is it true to connect CM of each story in a 3D problem to a leaning column via an axially rigid element in both longitudinal directions to capture the P-delta effects or I need to define such columns for all frames in both directions?
Best,

Dear all ...
How can I do a P-delta analysis in a 3 dimensional problem?
I use the leaning column method in my 2D problems.Can I use this method for 3D analysis, too?
Thanks ...

hello ... I tried to run my script using OpenSeesSP. It is a 3D 3-story RC frame with nonlinear concentrated hinges. the model runs very quickly in comparison to OpenSees in the pushover case. However, while trying to run the time-history analysis in OpenSeesSP, I got convergence problems. I used Pe...

Hello ...
please let me know, what changes should I make to my tcl scripts in order to run them on NEEShub in parallel?
I downloaded a .ppt file of Dr. McKenna presentation ...
unfortunately, i couldn't run my file in parallel.
thanks

Yes, but it is 23 MB! I cannot send it via e-mail

Try Constraints Penalty ... (see the manual for the arguments)

Is there any useful script for 3d modeling of RC frames using concentrated plastic springs and utilizing uniaxial material models ... I have made one, using the Ibarra-Krawinkler model and it crashes ... These are some of the commands I used to make a nonlinear spring concentrated at the end of beam...

m.y,
It is due to sanctions ... you should take it from your friends, who previously downloaded it ...

Tell me what the problem is ... I have run it without any problem, even for RC members ...
