Column forms a very important component in a structure. Supporting the slabs is the main function of the columns. Since columns support beams which in turn support walls and slabs, it should be realized that the failure of a column results in the collapse of the structure. The design of a column should therefore receive importance. Columns which show more ductile behaviour do not show a catastrophic failure and give warning prior to impending failure. The ductility of reinforced concrete columns is also important in evaluating their aseismicity behaviour, because the column with the excellent ductile behaviour would be capable of absorbing and dissipating seismic energy. In order to improve the ductility and various other parameters of the columns this project work advocates the use of DNA helical reinforcement along with steel and rubber ties as better substitute in place of conventional spiral helical reinforcement because of the improvements in the various column parameters observed by the use of DNA helical reinforcement in columns. It was found from the test results that there was a considerable amount of increase in the ultimate compressive strength, ductility, elastic modulus, shear modulus in the columns in which DNA helical reinforcement was used in comparison to conventional spiral helically reinforced columns.
