Abstract

In order to investigate the stability behavior of channels with complex edge stiffeners under axial load between fixed-ends,a total of 292 members with different parameters such as width-to-thickness ratio of flanges,section shapes,length of column,stiffener length were selected to be studied by nonlinear finite element analysis.The influence of the above parameters on stability behavior of channels with complex edge stiffeners were studied.It is shown that fixed-ended columns are more prone to distortional buckling.When width-to-thickness ratio of flanges is big,the overall instability mode tends to perform the flexural-torsional buckling.The ultimate load-carrying capacity of members decreases with the increase in the flange width-to-thickness ratio and slenderness ratio.With differences of width-to-thickness ratio of flanges,two different rules were shown about the influence of edge stiffeners on the load-carrying efficiency of members.
