Abstract: Cold-formed steel structures are a type of steel fabrication that is commonly employed in building construction. Before manufacture, they are designed precisely to the appropriate dimensions using the ABAQUS software. Both the strength of the cross-section and distortional buckling determine the load-carrying capability of the section. It was found that thin walls in some cold-formed sections suffered distortional buckling under light loads, and that these elements continued to be strong even after the members buckled. To prevent local buckling, stiffness is offered by the web part. There are several methods for determining the modes and elastic buckling stress. They are finite element analysis, finite strip analysis, and conventional Fourier series solutions. The thickness of the specimen and types of stiffener selection which influence the ultimate strength and deflection should be the issue in the design of the appropriate sigma section. The non-linear numerical analysis of the web-stiffened triangular section was performed using ABAQUS v6.4. It has been demonstrated that sections with height-to-thickness (h/t) ratios have load-bearing capacities. When compared to the lower h/t ratio sections, they demonstrated an improvement in load-carrying capability from 35.13% to 37.2%.
