Abstract |
In this study, experiments were conducted to evaluate the flexural performance of the RC column reinforced with hybrid FRP sheet. The experiments were carried out under reversed cyclic antisymmetric moment, such as seismic loads. The variables of the specimens is reinforcement with hybrid FRP sheet which was made up of aramid fiber and glass fiber. Experimental results showed that the specimen reinforced with hybrid FRP sheet exhibited a flexural performance equal to or higher than that of the specimen without hybrid FRP sheet. Moreover, ductility capacity increased by 1.9 times and energy dissipation capacity increased by 1.75 times, respectively, compared with the non-reinforced specimen. It was confirmed that the specimen reinforced with hybrid FRP sheet have sufficient structural performances which exceed requirements recommended by the design codes; KCI 2017 and ACI 318-14.
