Buckling Behaviour of Cold Formed Steel Column Subjected to Axial Compression Loading

Abstract. Cold formed steels are durable, reliable and cost effective options for low and mid-rise buildings. Analysing the behaviour of cold formed steel structures is a vital prerequisite for their further large scale applications. The previous studies on cold formed steel structures stated stiffness as a major reason for its application in the construction field. In this paper the cold formed steel structures were analysed for their behaviour when subjected to axial compression loading. The different heights of columns such as 700 mm, 750 mm and 800 mm has been taken for a constant thickness of about 2 mm. The strength and displacement of axial member against loading was investigated and the results were compared with the load displacement curve obtained numerically using Abaqus and CFS software. In this investigation, an attempt is made to study the ultimate load carrying capacity and the corresponding displacement with respect to height and the mode of failure.
