Ramgopal.L, M. Abhinav

Repairing of RC structures has become increasingly important, especially in the last decade. Carbon Fiber Reinforced Polymer (CFRP) is one of the new materials used to strengthen or repair RC structures. This paper presents a study on the behaviour of Carbon Fiber Reinforced Polymer (CFRP) laminates as a flexural repair system for Reinforced Concrete (RC) beams. The objective of the study is to investigate the flexural behaviour of RC beams strengthened by carbon fiber reinforced plastic (CFRP) laminates. The experimental program includes testing of 3 simply supported reinforced concrete beams of which 2 beams are strengthened with CFRP laminates, the remaining 1 beam will be fully solid without CFRP laminates and considered as control beam. The deflection, cracking pattern and ultimate load carrying capacity for RC beams bonded with CFRP laminates will be investigated. Test results in the current study show that the structural performance has been improved and the load carrying capacity increases by 26.4% with respect to control specimen.
