Beam nonlinear analysis

[bartosz_borowiak]

I'm working on some steel beam with big holes for services. I modelled them as a set of plates with correct stiffnes and was looking at von Misses stresses. Looks like near corner beam is yielding which is fully understandable. I would like to ask if there is possiblity to do nonlinear (2nd order) analysis so the stresses would get redistributed according to the defomed stiffnes matrix. I was playing with analysis type but I cant get realistic results.

Thank you fo any help.

Regards,

Bart
