Thank you very much, and I can understand that, but i don‘t know how to write the code about applying the equivalent force couple and load at the same time.

HI ,everyone
Could you teach me how to simulate the eccentric compression test of 3D-column in OPENSEES ？I just don‘t know how to apply pressure outside the column section.
I would appreciate it if you could offer any help！！！

hi guys, I am a green hand，When I build a model of T-section concrete-filled steel tubular column and simulate it under bias, the output is 0. I don't know what the problem is. I need your help. Thanks for any help!!! Here's the related running code I wrote. wipe puts "system" model basic ...
