An Experimental Study for Shear-Carrying Capacity of Reinforced Concrete Beam with GFRP Stirrup

GFRP 스터럽으로 보강된 콘크리트 보의 전단성능에 관한 실험적 연구

Recently, many researches for high-strength and high-durability concrete structure have remarkably been studied by adopting new construction material, fiber reinforced polymer (FRP). In connection with these research trend, the shearing capacity of concrete beams reinforced by GFRP stirrup which is developed in this study was evaluated. Experimental variables are span to depth ratio and spacing of shear reinforcement for test. In the result of test, the crack pattern, failure mode and shear load between shear steel reinforcement specimen and GFRP stirrup reinforcement specimen showed similar structural tendency. Therefore, it was investigated that the adaptability of shear-reinforced concrete structure with GFRP stirrup will be improved with further researches of shear design variables.
