Review on Light Gauge Steel I- Section under Compression with Flange Stiffener

Cold-formed steel structures has increased rapidly in recent times due to significant improvements to manufacturing technologies and development of thin, high strength steels. The use of cold-formed thin walled steel structures has greater than before in recent years, and some built-up section members are aggravated and widely used for their excellent structural behaviors. The differences of global, local and distortional buckling behaviors among members with built-up and single sections are investigated. This paper presents a detailed review on cold-formed steel channel sections, which are subjected to both axial and eccentric compressive forces. Different cross-sections with single and built-up configurations are presented in this paper. Literature pertaining to experimental, theoretical and numerical investigations is reviewed in detail. The main objective of this literature survey is to study the available literature and to propose the required research work for the development of various other single and compound cold-formed steel sections. Research in cold-formed steel channel sections subjected to compressive forces shows the importance of channel sections and compares with other possible sections.
