This research paper explores the flexural performance of reinforced concrete beams using glass fiber-reinforced polymer (GFRP) bars, with an emphasis on analyzing the effect of varying GFRP reinforcement ratios. The study highlights the diverse strength capabilities, lightweight properties, corrosion resistance, and cost-effectiveness of GFRP bars, positioning them as a promising alternative in construction applications. Through a comprehensive analysis encompassing numerical, analytical, and experimental investigations of GFRP bars, the research aims to offer valuable insights for optimizing structural design and enhancing overall performance. Additionally, the paper highlights potential avenues for future research, such as investigating long-term durability, examining alternative FRP materials, and evaluating FRP-reinforced structural members under dynamic loading conditions.
