ABSTRACT
Cold-formed steel sections are traditionally considered with no plastic capacity, and consequently non-ductile, mainly due to wall slenderness involving local instability phenomena. However, even they do not have sufficient plastic rotation capacity to form plastic hinges, they can form local plastic mechanisms. The main aim of present paper is to provide evidence for post-elastic capacity of cold-formed steel sections in compression and bending. Also, comparisons with FEM simulations are presented.
