Evaluation of Flexure Performance of Beam Hybridized with PVA Fiber and GFRP Bars

This study's goal is to present the use of PVA fibers, Poly Carboxyl Ether (PCE) superplasticizer, and glass fiber-reinforced polymer (GFRP) as reinforcement bars in concrete beams. There were four examples, each with a unique reinforcement and PVA fiber ratio. Two specimens, known as pure FRP beams since they only contained GFRP reinforcement and two hybrid fiber-reinforced polymer (HFRP) beams. Following dosing experiments with concrete, the volume fraction of PVA fiber in two specimens of the pure FRP beams and HFRP beams, respectively, was 0 and 0.25%. Pure FRP beams produced outcomes that weren't suitable for the beam considerations needed. In contrast, when compared to pure FRP beams, the HFRP beams performed better and produced satisfactory results. The results of this study, which examined the load–deflection capabilities of all the specimens described, demonstrated that HFRP beams had a higher load carrying ability and that a PVA fiber dosage of 0.25% produced favorable outcomes. Even though the HFRP beams had a strong capability for carrying loads, they deflected more than the others.
