Plastic re-destribution stresses

How I can modelize a plastic redistribution of stresses in an steel shell?
I have a steel shell for a water tank supported horizontally by steel frames. Doing an elastic analysis huge peak stresses appear on and next to the supports, I would like to modelize a plastic redistribution of the stresses when the matirial reach the elastic limit.

Maybe make not nodal support or connect this support with the nearest nodes by rigid links?
