Evaluation of Ductility of Hybrid Reinforced Concrete Beams Made with Glass Fiber-Reinforced Polymer Rebar

Concrete is a robust, adaptable, and moldable building material. Cement, fine aggregate, coarse aggregate, and water are the main ingredients. For concrete to perform better than traditional concrete, several researchers have added novel components. One of the best polymeric fibers for use in concrete is polyvinyl alcohol (PVA) fiber, although the design of the material is made more difficult by PVA fiber’s particular microstructure. One of the most advanced composite material types that may be employed in a variety of civil engineering applications is GFRP rebar. Due to its advantageous characteristics, such as a high strength-to-weight ratio, GFRP reinforcement is becoming increasingly popular. Neutrality to magnetic fields and corrosion resistance. The capacity of reinforced concrete members to withstand significant deflection before failing is known as ductility. This property of structural members made of reinforced concrete is essential since it indicates when a component is failing and prevents catastrophic collapse. In the current study, M30-grade concrete was subjected to an experimental inquiry to establish its ductility. Two numbers of GFRP bars and conventional steel bars were used, and a comparison was done between concrete with and without 0.25% PVA fibers. Tensile strength measurements are made between GFRP and steel bars. The test results for the beams employing GFRP and PVA fibers are established during a 28-day curing period.
