Abstract

Abstract: A total of 18 simply supported axial compression members with three types of complicated sections were tested. The bearing capacity， buckling mode and deformation behavior of these members were studied. The results show that cap shaped stiffeners can increase the ultimate load-carrying capacity of loaded members obviously. Compared with channels with complex edge stiffeners under the same condition， members with cap shaped stiffeners can make the ultimate load-carrying capacity be increased about 10% to 40%. Distortional and local interaction buckling became the main buckling modes. Numerical simulations were performed by finite element analysis. The analysis results are in good agreement with experimental data.

Key words: channel with complex edge stiffeners, element with cap shaped stiffeners, static test, load-carrying capacity, buckling mode
