A comparative analysis of resistance models for austenitic stainless steel girders subjected to concentrated loads

The increasing use of stainless steel in construction has led to the need of developing resistance models for structural elements made of this material. Unlike carbon steels, stainless steel alloys exhibit stress-strain curves with a pronounced strain hardening capacity and reasonable ductility tha...
