Using the current direct strengths method to predict the bearing capacity of channels with complex edge stiffeners and stiffeners in the web, it will make the excessively conservative results to the test data for it couldn’t account for the interaction between distortional and local buckling. In order to study the method for bearing capacity of channels with complex edge stiffeners and web stiffeners under axial compression, the paper revised the current direct strengths method and new proposals considered distortional and local interaction buckling were made. The proposed method was verified by the finite element analysis results and the test results. It shows that the member strength predicted by the proposed method is more accurate than the present method and agrees well with the test data. Furthermore, compared with the results of the finite element method and hand method, the hand method for calculating elastic buckling critical stress of web-stiffened lipped channels with complex edge stiffeners was validated.
