| Abstract: | Using Finite Element Method program ANSYS as well as considering the initial imperfections such as initial geometrical imperfections, residual stresses and cold-formed effectiveness, the axial compressive ultimate loading capacities are analyzed of cold-formed steel square hollow section member,rectangular hollow section member with thick wall and hot-rolled H-section member. The Finite Element Method analysis results are compared among them. The corresponding conclusions are drawn and the references to design columns are provided. |
