The use of columns having steel and concrete as composite sections is popular over a long time. At the start it absolutely was wont to give sufficient protection to the steel structures. But later on, the concrete sheathed columns came in trend in respect to enhancement of strength properties. However, till the sixties, such concrete filled steel tubes were never analyzed or used. Nowadays, such composite structural parts are progressively utilized in bridges, tall buildings and alternative styles of structures due to its composite effects. Such sections provide much economical structural system when compared with traditional structures having reinforced concrete structural members. In the following study a concrete filled steel tubular column is modeled and analyzed in finite element analysis software ABAQUS. Stress, strain behavior along with buckling analysis of CFST and RCC column is done for different lengths and cross sections to analyze the behavioral changes in compressive strength of columns.
