Usage of cold formed steel structural components for buildings and structures is gaining popularity in India
for a decade. Most effective use of Cold-formed steel can be made for different purposes since they are economical in
production. This paper presents the details of the finite strip models developed to investigate the buckling behaviour of
cold-formed steel column. Cold-formed steel is vulnerable to buckling due to its thinner section which affects the strength
of the section. In order to assess the influence of buckling, four thicknesses (1.2mm, 2mm, 3.15mm, 4mm) were chosen.
Finite strip analysis was performed using CUFSM software. Parametric studies have been conducted for ratio of web
height to flange width and ratio of lip length to flange width
