This article investigates the numerical and theoreticalstudy on the b uc kl i ng behaviour of cold formed steel lipped
angle columns under pinned end conditions. The sections were analyzed using ABAQUS software. Geometric andmaterial non
linearities were included in the model. Parametric study was conducted by varying the thickness and length of the specimens.
Three types of sections were chosen for this study based on the geometric limitations for the prequalified sections provided in
the North American Specifications for Cold formed steel structures (AISI S100 – 2007). The Analysis was conducted on 24
specimens. All the specimens were failed under the combination of Local and Distortional Buckling. Theoretical study was
carried out using Direct Strength Method as per North American Specifications for Cold formed steel structures. The
Numerical results were compared with the Direct Strength method. Based on the comparison of results suitable
recommendations were suggested in the direct strength method.
