Mate,
I think you need to be a little bit more clear with your question. I'm not a 100% sure what you are asking for.
Do you want an FEA solver that can model the non linear properties of steel, under various loading conditions?
If that's what you want:
Femap with Nx nastran; Ansys Mechanical; Altair Hyperworks are all worth checking out. Ansys, is by far the most user friendly.
