In building construction there are basically two types of structural steel, hot-rolled steel shapes, and cold-formed steel shapes. The manufacturing process of cold-formed steel involves forming the material by either press-braking or cold roll forming to achieve the desired shape. The built-up CFS columns have better performance than CFS columns of single-channel sections. In this study, the structural performance of new types of composite columns: I-shape, C-shape, and Z-shaped CFS columns of partially concrete-filled and fully concrete-filled are analyzed. This axial performance is compared with hot rolled sections (ISMB) using ANSYS 19. A finite element analysis (FEA) model was developed to simulate the structural performance of these specially shaped CFS columns. Columns were analyzed under axial loading conditions. Investigation in buckling improvement due to partially and fully filled in CFS has good scope in the cost-effective method of improving stiffness and strength. Global buckling was the major failure mode detected. From the comparison, it was observed that the weight of CFS is half of ISMB and fully filled concrete CFS I-shaped section has a 111% increase in load than ISMB section
