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！！！

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.
