| Abstract: | Based on the experimental investigations of load-carrying capacities of super thin-walled high-strength cold-formed steel channel columns with intermediate stiffeners in web subjected to axial compression,the calculation method for the effective area of cold-formed thin-walled plate elements with intermediate stiffeners was discussed with reference to the related calculation formulas,and an equivalent element method(EEM),for estimating the effect area of cold-formed thin-walled steel plate element with inte... |
