| Abstract |
A FRP shear reinforcement is proposed for the design of reinforced concrete beams. The FRP shear reinforcement is manufactured into a plate shape and has several openings on it for its perfect integration with concrete. It is embedded into concrete with main steel reinforcement during construction stage. In this paper, the performance of this proposed shear reinforcement is investigated by performing a structural test on six concrete beam specimens with shear span to depth ratio of 2.4. Test parameters include the type and shape of FRP shear reinforcement. The effects of these parameters on the shear strength of the FRP reinforced concrete beam are examined. A shear strength equation for concrete beams with the proposed FRP shear reinforcement is suggested by a proper modification of the existing shear strength equation for concrete beams with steel stirrups in ACI 318-11. The comparison between the test results and the estimation by the proposed equation generally shows a good agreement between them. |
