Outcomes of this experimental study on large-scale GFRP-reinforced concrete beams show that hooked-end bars would provide excellent bar anchorage compared to that provided in case of straight-end bars. On the other hand, the experimental results of the two beams designed with hooked-end bar lap splices failed due to concrete crushing within the hooks at about 50% greater moment capacity than their theoretical design value. Test results show that the two beams with straight-end bar lap splices achieved the theoretical design moment resistance, and both specimens failed due to slippage of the bars. Beams were designed in accordance with CSA-S806-12 (CSA 2012) design standard and were tested under four-point flexure bending until failure. Two beam specimens were designed using 550 mm long lap splices that utilized straight-end bars, while the other two specimens were designed with hooked-end bar lap splices. Four large-scale concrete beams reinforced with glass fiber-reinforced polymers (GFRP) bars were experimentally tested to investigate the bond strength between the reinforcing bars and concrete.
