Open cold-formed steel sections such as C, Z, Hat and rack sections are relatively small because of their simple forming procedure and easy connections but they suffer from buckling modes due to their mono-symmetric, point symmetric nature, high plate slenderness, eccentricity of shear center to centroids and low torsional rigidity. An innovative tiny bracing system is proposed to reduce or avoid distortional buckling and also the effect of lipping compared to the tiny bracing will be investigated. Finite strip analysis is carried out to determine the load and the location of the bucking modes. Both analytical and experimental study on the C section will be compared. Simple C sections with and without Lips are tested to understand the different buckling modes and the failure loads are compared with the analytical solutions.
