Abstract:
An improved method for evaluating the shear resistance of fiber-reinforced polymer (FRP) reinforced concrete members without stirrups is presented. The effects of shear and moment interaction at section and of member size on its shear strength are considered. For beams with a span-depth ratio (a/d) less than 2.5, the effect of shear transfer by arch action is taken into account. Following the traditional ACI approach, the concrete contribution is defined as a function of the square root of concrete strength, but the contribution from the aggregate interlock mechanism is expressed as a function of the cubic root of the axial rigidity of longitudinal reinforcement. The member size effect on its shear strength is also considered. The predictions of the proposed method are in better agreement with available experimental data than those of any of the current shear design methods for FRP-reinforced concrete structures.
