Analytical Model to Predict Punching Shear Strength of FRP-Reinforced Concrete Flat Slabs
This study proposes a simple and reliable framework to evaluate the punching shear capacity of reinforced concrete slab-column connections internally reinforced with fiber-reinforced polymer (FRP) without shear reinforcement. This method was originally developed for concrete slabs reinforced with conventional steel. The effects of the FRP elastic modulus, ultimate tensile strength, and bond characteristics, which are sufficiently different from those of steel, are incorporated in the existing model. The predictions of the proposed model for FRP-reinforced slabs are then compared with test results obtained from 28 slabs recently reported in the literature. The comparisons show excellent agreement between the predicted and experimental values. The findings from this study indicate that the proposed predictive equation is reliable for analyzing the punching strength of slabs reinforced with FRP grids or bars.
