Behavior of GFRP-RC Slab–Column Edge Connections with High-Strength Concrete and Shear Reinforcement

Volume 22, Issue 2
Abstract
This paper presents the experimental results of seven full-scale glass fiber-reinforced polymer (GFRP) reinforced concrete (RC) slab–column edge connections. The dimensions of the slabs were with a square column measuring . The test connections were divided into two series. Series 1 included three high-strength concrete (HSC) connections, investigating the effect of the flexural reinforcement ratio (0.90, 1.35, and 1.80%); and Series 2 included four normal-strength concrete (NSC) connections, investigating the effect of the GFRP shear-reinforcement type (headed studs or corrugated bars) and pattern (six or eight lines of shear reinforcement). The test results showed that increasing the reinforcement ratio increased the punching capacity and the postcracking stiffness of the HSC connections. The test results also showed that the use of headed studs and corrugated bars increased the punching capacity and the deformability of the NSC connections. The test results were compared to the predictions of the Canadian and American design provisions for FRP-RC structures.
