Abstract: Most of the Indian buildings are vulnerable to seismic action due to improper reinforcement detailing within the beam-column joints. The reinforced concrete frames without seismic provision are often characterized by an unsatisfactory structural behaviour due to low available ductility and lack of strength which in turn induces global failure mechanism. Hence it is very much essential to retrofit the vulnerable building to cope up for the next damaging earthquake. In the present work, experimental and analytical investigations have been carried out to study the structural behaviour of columns strengthened by Glass Fiber Reinforced Polymer (GFRP), Carbon Fibre Reinforced Polymer (CFRP), Reinforced Concrete jacketing (RC), Steel plate, Steel strip, Corrugated steel jacketing and Ferro cement jacketing of beam -column joint. The entire study was divided into 5 distinct phases. In the first phase, the performance of Reinforced Concrete columns subjected to cyclic loading is studied to determine the desirable percentage of longitudinal reinforcement. In the second phase, six experiments were conducted to find out the effectiveness of using Fibre reinforced polymer jackets for enhancing the seismic shear strength and ductility of column. In the third phase, nine experiments were conducted to find out the effectiveness of using Reinforced concrete jacketing. In the fourth phase, seven experiments were conducted to find out the effectiveness of using steel plate, steel strip and corrugated steel jacketing of column for enhancing the seismic shear strength and ductility. In the fifth phase, four experiments were conducted to find out the effectiveness of Ferro cement jacketing of column for enhancing the seismic shear strength and ductility. Comparison of load carrying capacity, energy dissipation capacity and ductility of the specimens retrofitted with CFRP, GFRP, RC, Steel and Ferro cement jacketing were made.
