Cold-formed steel has many advantages to construction, such as high strength to weight ratio, ease of handling, transportation and sustainability credentials. However, the structural behaviour of built-up cold-formed steel members characterized by various buckling modes is not yet fully revealed. A lack of fundamental understanding of the behaviour of built-up members, as well as the absence of sufficient design guidance in the current design codes (AISI S100 -2016; CEN 2005; IS:801), often lead designers to use overly conservative assumptions, which prevents the exploitation of the real potential of these types of sections. In these study choosen built-up section are subject to experimental testing and the Numerical analysis was carried out using ANSYS 18.2.Also,this study investigates the buckling behaviour and capacity of built-up cold-formed steel members subjected to bending.
