Abstract

The aim of the study is to investigate the distortional buckling behaviour of intermediate cold-formed lipped channel sectionunder pinned end condition subjected to axial compression. An extensive test and numerical investigation of cold-formedlipped channel column with various types of intermediate web stiffeners is presented. In this study, three types of intermediateweb stiffeners are chosen such as V, U and Σ . The entire cross-sectional dimensions meet with the pre-qualified columndimension given in Direct Strength Method for cold-formed steel structures. Totally, 12 columns are tested and results arecompared with the numerical analysis. Numerical analysis is carried out using software ABAQUS. Material and geometricimperfections are incorporated in the FE model. Selected section dimensions met with the distortional buckling mode. Goodcorrelation is achieved between experiment and finite element analysis. All the results are compared with the Direct StrengthMethod specifications for cold-formed steel structures. Based on the comparison of results, a suitable design modification isproposed. Furthermore, results are verified with the existing results which are available from the literature.
