Abstract:A new type of fiber-reinforced polymer (FRP) shear reinforcement is proposed for reinforced concrete beams. The new FRP shear reinforcement consists of FRP plate material with openings. The performance of the proposed shear reinforcement was investigated by performing tests on nine concrete beam specimens with a shear span-depth ratio of 2.4. Test parameters include the type of FRP, shape of FRP shear reinforcement, and the amount of the FRP reinforcement. The effects of these parameters on the shear strength of the FRP plate shear reinforced concrete beam were examined. A shear strength equation for concrete beams with the proposed FRP shear reinforcement is proposed based on modifying the existing shear strength equation for concrete beams with steel stirrups in ACI 318-11. The comparison between the test results and the estimations by the proposed equation generally shows good agreement, and the test results indicate that the proposed system is a promising candidate for shear reinforcement in FRP reinforced concrete beams.
