The last few years have seen increasing usage of cold formed steel sections as load bearing members as opposed to secondary systems. In this context a study is being made to analyse Coupled Channel sections to arrive at design strength criterion in compression. The direct strength method of design for cold formed steel sections has been validated over the years through research and the same has been incorporated in the standard codes of practice in the countries like USA and Australia. ABAQUS and CUFSM has been extensively used to perform Finite Element analysis and Finite Strip method of thin walled cold formed steel sections and the results are compared to each other. Hence the analysis is being done on CUFSM and ABAQUS. The design strength curves will be arrived at using direct strength method. In this study, the behavior of Coupled Channel sections under the action of axial loads has been carried out. In ABAQUS, the loads are applied on both ends. The simply supported and clamped end conditions are considered.
