Abstract: Cold Formed Steel CFS members are widely used in residential industrial and commercial buildings as the primary load bearing structural elements due to their advantages such as higher strength to weight ratio over other structural materials Cold formed steel members are often made from thin steel sheets and hence are more susceptible to various buckling modes The current cold formed steel sections such as C and Z sections are commonly used because of their simple forming procedures and easy connections but they suffer from certain buckling modes newlineUnder flexure cold formed open cross section exhibits three modes of instabilities local lateral torsional buckling and distortional buckling In the design codes effective widths of the plate elements are considered to calculate moment capacity of beam The present Indian code of practice for design of cold formed steel members is under revision Generally codes provide design criteria for C Z and I sections If the higher moment capacity is needed the depth of web should be larger But thin web provided is subjected to local buckling and it has to be stiffened An alternate method of stiffening is provided with corrugation in the web Corrugation may be of sinusoidal triangular or trapezoidal profile It is therefore important to strengthen the web and to increase the moment capacity of these members newline newline
