Abstract
Many reinforced concrete structures in our country are in a deteriorated or distressed state. Beam–column joint is the very important zone in a reinforced concrete moment resisting frame. Failure of beam-column joints is main reason of collapse of many moment-resisting frames. Hence strengthening such structures or increasing the load limit on structural component is becoming necessary to extend their service life. Covering research has been carried out in recent years on the use of fibre-reinforced polymer (FRP) composites in the strengthening of reinforced concrete (RC) structures. Different applications of fibre reinforced polymer composites (FRPCs) for external strengthening in civil construction are reviewed in this paper. Experimental as well as analytical and mathematical research contributions have been focussed in the review. The main structural component such as beam-column joints, have been reviewed and structural behaviour of component is discussed briefly. The efficiency and effectiveness of carbon fibre-reinforced polymer (CFRP) sheets which increasing the shear strength and ductility of deficient beamcolumn joints have been studied. This paper provides a concise review of existing research on the behaviour and strength of FRP strengthened RC structures elements, with a strong focus on those studies which effected directly to the development of strength models. Finally, all concluding remarks are given along with possible future scope of research.
