Composite Columns are constructed using various combination of structural steel and concrete in and attempt to utilize the beneficial properties of each material mainly tree types composite columns has been widely applied to industrial building that required large size columns and fast construction are use in rise building construction. Experimental study on the behavior of concrete filled steel tubular columns (CFST) axially loaded in compression to failure. Shear connector of nominal diameter 6 mm and a length of 80.3 mm. The bolt holes in the pipes were used of one mm oversized to facilitate erection adjustments. The results show that the use of high strength infill concrete is much more effective to get extra strength with same size of CFST column and use of shear connector increases the strength of column with the same size of column dimensions give a D/T ratio of 19.33(circular) and 16.66(square) to avoid local buckling effect. The experimental analysis of the data was done using the Regression analysis and an equation was developed in order to correlate the strength between shear and non-shear component of the Composite member. The developed equation can thus predict the behavior of the column without actual testing.
