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!!!

Apply an equivalent force couple to the column node. Force "P" and moment "P*e" where e is the eccentricity.

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.
