Abstract

A simple method is proposed to predict the ultimate load of cold formed steel lipped channel columns. The proposed method reliability based on finite element method results of the cold-formed C- channel columns under axial load [1]. Numerical investigations of buckling behavior are accomplished by using FE software ANSYS 16 [2]. A parametric study for different cross sections is carried out covering a wide range of slenderness and web depth to thickness ratio for lipped channel columns. The comparison between results obtained from the numerical method (FEM) and the proposed method is achieved to validate the precision of the simple prediction method. Finally, the proposed method is implemented on the double lipped channel columns.
