Concrete Shear Strength of High Strength Concrete Beams Reinforced with FRP Bars

This study evaluates the concrete shear strength for normal and high strength concrete beams reinforced with 3 type FRP bars (CFRP, GFRP, HFRP). Experimental results obtained from twenty-four simply supported concrete beams are compared with values predicted by FRP shear strength expressions proposed in the various literatures, including the ACI Committee 318 and ACI Committee440. The shear strength correction factors are proposed through the regression analysis.
