The Elastic-plastic Local Stability and Load-carrying Capacity of Compressed Thin-walled Steel Members

摘要

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 (Juhas, P. 2006). The aim of this research is to investigate and analyze the elastic-plastic post-critical behaviour of thin web and its interaction with flanges. The experimental program, test members and their geometrical parameters and material properties are evident from Tables 1, 2 and Figures 1 and 2. The test arrangement and failures of the test members are illustrated on Figures 3, 4 and 5. Some partial results are presented in the paper, too.
