In recent years, the use of concrete filled steel tube columns is increased significantly in medium-rise to high-rise buildings, therefore to understand the load deformation characteristics of composite columns critically, numerical finite element analysis using software package ANSYS is carried out in this paper. This paper focuses on modelling of concrete filled steel tube (CFST) column under axial loading. The main parameters of FEA are circular and square column with varying grades of concrete (30, 50, 70, 90 N/mm2). It is concluded that the deformation of the column is decreasing 10-15 percentage with increasing grade of concrete.The deformation was influenced by the shape of the CFST section. The circular section leads to better behavior than square section due to better confinement.
