The aim of this paper is to choose the efficient cold formed steel section profile for a fixed cross-sectional length, thickness and height of the column. In this work six types of sections wereselectedsuchasRC-1600-1.6-SP1,RC-1600-1.6-SP2,RC-1600-1.6-SP3,RC-1600-1.6-SP4,RC- 1600-1.6-SP5 and RC-1600-1.6SP6 .The efficient section is chosen based on the design buckling resistance of the column by performing Numerical and Theoretical analysis. The Numerical analysis is performed using ANSYS 12.The elastic section properties of thecolumnsarepredictedbyperformingFinitestripanalysisbyusingopensourceprogramCUFSM.The design buckling resistance of the columns are predicted by using Finite element toolANSYS.The columns are chosen with a cross sectional length of 544.36 mm and a thickness of 1.6mm. The end condition of the column is considered as hinged-hinged. The height of the column is1600mm.Thematerialpropertiesof the cold formed steel such as Yield Stress, Modulus of Elasticity, Tangent Modulus,etc are obtained by conducting the coupon test. The theoretical analysis is performed using various codal provisions such as Direct Strength Method - S100:2007 (North American AISI Specifications), Australian/New Zealand Standard Code -AS/NZ: 4600- 2005 and by British Standard BS EN 1993-1-1-3: 2006.The bilinear elastic-perfect plastic behavior of material is considered for analysis. The material and geometric nonlinearity is included in the finite element model. The linear elastic buckling analysis followed by non-linear ultimate strength analysis is performed to obtain the buckling load, buckling mode and ultimate load capacity of the sections. In theoretical analysis the Design buckling resistance may only vary based on the reduction factor and effective cross sectional area of the column. The buckling resistance of the column obtained from both Numerical and Theoretical analysis are compared for all types of cross section and thus the efficient cross section is selected.
