The elastic-plastic bearing capacity investigation of thin-walled steel members with quasi-homogenous and combined cross-sections

Abstract

The paper presents fundamental information about realized experimental-theoretical research to determinate the load-carrying capacities for thin-walled compressed steel members with quasi-homogenous and hybrid cross-sections. The webs of such members are stressed in the elastic-plastic region. The research joins on previous research of the first author of the paper [1]. The aim of this research is to investigate and analyze the elastic-plastic post-critical behavior of thin web and its interaction with flanges. Some experimental results are presented in the paper.
