In construction industry cold formed steel section (CFS) is highly preferred in purlins, girts, studs in walls and shear wall chords. Based on its strength requirements, CFS can be produced in the desired cross-sectional dimensions and shapes. The majority of wall studs are made of cold-formed steel, which is typically channel section. Hence, this study aims to compare the buckling behaviour of cold formed steel channel section, sigma section, and built-up sigma section. An experimental and numerical analysis conducted to know the buckling capacity of cold-formed steel section subjected to axial compression. The load- deflection and failure modes are discussed in this study. Additionally, the strength-to-weight ratio of channel sections, sigma sections, and built-up sigma sections was compared. The built-up sigma section has superior performance relative to the single section. Furthermore, finding indicates that the sigma section surpasses the C-section.
