Review of Literature

Research into the buckling behaviour of cold-formed steel section has concerned significant awareness in recent years. The design specifications for an edge and intermediate stiffened elements was first to propose by the researchers [1]. Similarly, local and distortional buckling interaction of thin-walled sections was foremost to report by the researchers [2], similar studies were conducted by the literatures [3–5]. Recently, local/distortional/global interaction research carried out by the researchers [6–10]. Likewise, distortional buckling behaviour was conducted by the researchers [11–13]. Stub column tests of thinwalled complex section with intermediate stiffeners were discussed by the author [14], in continuation of this by author have again numerically studied by the author [15], using FEA, effect of intermediate stiffener on the flange and web, geometric imperfection, slenderness ratio and end boundary conditions on the distortional buckling strength of the complex thin walled section. They also evaluate the effectiveness of DSM equations and also provide the modifications of the same for the complex thin walled section. The author [16] evaluates the suitability of AISC, AISI and DSM equation for locally slender columns and gave the suitable recommendation for the design methods. Failure analysis of composite lipped channel columns under axial compression discussed by the author [17].
