This paper studies about the buckling analysis of multi-material structure especially compressed column using topology optimization. The buckling is stated as a constraint in the optimization problem. A clamped-pinned column with applied axial compressive load is analyzed. An active-phase algorithm is used to solve multi-phase topology optimization problem. The distribution of different materials is determined in a isotropic two-dimensional design domain. The material properties is modified based on the Solid Isotropic Material with Penalization (SIMP) interpolation approach. The Method of Moving Asymptotes (MMA) is used to update the topology design variables which is relative element densities. The optimal designs of the column structure are presented and discused in the numerical applications.
