Composite column are structural members, which are mainly subjected to forces and end moments. The steel tube serves as a formwork for casting the concrete, which reduces the construction cost. No other reinforcement is needed since the tube itself act as a longitudinal and lateral reinforcement for the concrete core. The Concrete filled steel tube member has many advantages compared with the conventional concrete structural member made of steel reinforcement. Concrete filled steel tubes are frequently used for columns, caissons, piers & deep foundations because of their large compressive stiffness. These composite sections have the rigidity and formability of reinforced concrete with the strength and speed of construction associated with structure, thereby making them economical. In the present study, an experiment is conducted on rectangular and square hollow structural steel with and without infill under compression and flexure. The infill material used in the hollow sections is conventional concrete and light weight concrete with chemical bond and mechanical bond. Compression and flexure tests are performed on the specimens and the behavior of the specimens are plotted. The behavior of hollow specimens with and without infill is observed from the experiment also effect of bonding between the concrete and steel is obtained. The results obtained from the experimental work are compared with numerical study by Finite Element Modeling using ANSYS.
