Abstract: Both experimental and analytical investigation using ANSYS program have been performed on 2500 mm long with 0.8 mm thick steel core. These cores were placed with #8 diameter rods of Fe 415 as reinforcement and filled with M20 grade self compacting concrete. Concrete Filled Steel Fluted Columns (CFSFT) with and without longitudinal reinforcement. Behaviour of concrete filled steel fluted columns having triangular flutes have been investigated by conducting experiment on thirteen columns. The parameters that have been chosen for the study are L/D ratios of 15, 20 and 25 and the number of reinforcements 3, 4, 5 and 6 of #8. The columns were placed on smooth plates at both ends and the columns were axially loaded and have been analysed for its stiffness and strength which have been presented. The percentage increase in strength from ANSYS specimens were 6.25%, 6.02% and 12.59% respectively. Axial deformation obtained from experiments in stiffness for L/D ratios of 15, 20 and 25 70.61%, 62.69% and 63.18% increased as compared to ANSYS.
