Shear-Reinforcing Effect of Continuous Fiber Rope on Reinforced Concrete Beams

摘要

Continuous fiber rope (CF rope) made of aramid fiber or vinylon fiber has been developed to apply for the reinforcement of concrete members and structures. It is characterized by a light weight, high tensile strength, and excellent durability compared with reinforcing steel bar. It has also good transportability, and it is flexible to be easily arranged at the construction site. The purpose of this study is to investigate the shear-reinforcing effect of CF rope. First, the reinforced concrete (RC) beams without shear reinforcement were tested. Then, the RC beams wound with CF rope at shear span were tested. Moreover, the shear-reinforcing effect of CF rope on the RC beams that were predamaged in shear assuming seismic retrofitting was also investigated. Through the test results, we confirmed that CF rope was effective for the RC beams without shear reinforcement and the predamaged RC beams in shear.
