This paper presents a detailed numerical study of the flexural buckling strength and axial cyclic response of a cold-formed steel (CFS) channel built-up battened columns. A total 36 double channels welded back-to-back and double channel welded as face-to-face both with lip as well as for without lip batten built-up columns testing are carried out for failure with pinned ends and fixed end. A total column is divided for different slenderness ratio with respective to different channels section and their behaviour is studied. To study the effect of lip, and the effect of symmetricity of cross-section on the ultimate load carrying capacity for different slender condition. Cold-formed steel sectional dimension and properties values are taken from IS 811-1987. Geometric and material non-linearity have been included in the finite element model and the flat width to thickness ratio of all specimens are kept less than the limiting values as per IS 801-1975. Built-up batten columns are design as per IS 800-2007. Design column strength calculate by using the finite element analysis (FEA) and the axial cyclic response of a cold-formed steel batten columns are compare with each other. Also compare pin ended and fix end columns were pin end columns take lesser load due to buckle in mid-section
