Abstract

In this paper, a new type of GFRP shear reinforcement is proposed for reinforced concrete beams. The new GFRP shear reinforcement is manufactured into a plate shape with several openings to ensure high adhesion property with the concrete. The test was performed on six concrete beam specimens with shear span-to-depth ratio of 2.4 to experimentally investigate the performance of the proposed shear reinforcement. Test parameters include the shape of GFRP shear reinforcement and the amount of the GFRP reinforcement. We examined the effects of these parameters on the shear strength of the GFRP plate shear reinforced concrete beam.A shear strength equation for concrete beams with the proposed GFRP shear reinforcement is proposed based on modifying the existing shear strength equation for concrete beams with steel stirrups in ACI 318-11. Comparing the test results with the estimations based on the proposed equation, the results generally shows good agreement. Results from this paper show that the proposed system is a promising candidate for shear reinforcement in GFRP reinforced concrete beams.
