material non linearity

[ichnos]

hi all
how can I do a non linear analysis limiting the stresses in the elements (shells, frames, solids)?

For frames, you can use either hinges or links to model localized nonlinear behavior. Additional information about links and hinges in SAP2000 can be found here (section "Should I use hinge or link?"):
