Abstract

Abstract: In order to further understand the mechanical behavior of the channel columns with complex edge stiffeners and cap shaped stiffeners，the stability of channel columns under axial and eccentric compressive loading was studied by the finite element program called ANSYS. Effects of specimen length， the width to thickness ratio of plate， section types and the eccentric distance on stability，buckling mode and deflection behavior of channel columns with complex edge stiffeners and cap shaped stiffeners were investigated.The results show that under the same condition，the bearing capacity of members with section C2 is 10%~20% larger than that of C1， and the bearing capacity of members with section C3 is 40%~50% larger than that of C1. When it comes to the maximum load， the channel column with cap shaped stiffener on web takes on negative eccentricity， while the channel column with cap shaped stiffener on both web and flange takes on positive eccentricity.

Key words: channel with complex edge stiffeners, element with cap shaped stiffeners, finite element analysis, eccentricity, stability behavior
