Experimental Study on Flexural Behaviour of Cold Formed Steel Section

Abstract

Cold-formed steel has been widely used in construction industry. In this paper, an attempt has been made in order to investigate the property of cold-formed steel by flexural behaviour of a channel section connected back to back. The flexural behaviour is evaluated both theoretically and experimentally and the results are compared in this study. In the experimental work, sections with nominal dimension 200 x 80 mm and 1.5 m length were loaded vertically while the lateral deflection were unrestrained to allow flexural buckling. The main objective of this study is to check the flexural strength of the specimen. Cold-formed steel (CFS) section under this study is the popular and emerging in the past decades. The property of the cold-formed steel makes it economic and feasible. The study of structural behaviour of cold-formed steel can make it easier to know its property and usage.
