Nowadays, Composite sections of the steel and concrete have been utilized and considered around the world, yet filled tubular columns require more consideration. Broad examination work has been done in Japan in the most recent 15 years on this. This present attempt shows a trial study on the performance of Concrete Filled steel Tubular columns (CFT).The present research work depicts about signifying the utilization of Concrete Filled steel Tubular columns (CFT) instead of Reinforced Columns & to determine the conduct of composite columns. For this purpose sixteen numbers of columns with various cross area and different thickness of steel tube (8 short columns and 8 long columns) is subjected to external axial prestress and lateral loads. The circular and square composite columns are casted with different L/D apportion and wall thickness. The concrete used is M20.It is observed that Circular composite columns has less deflection and high load bearing capacity with deferred buckling while compared to the square composite columns.
