102 - str - mus stiffening of cold - formed steel section at plastic hinge formation

This study is carried out to investigate the method that can be used to stiffen the cold-formed steel section so that the section becomes a plastic section and thus can be used for plastic design of portal frame. In this study, experimental works have been done to study the formation of plastic hing...
