Conventional Reinforced Concrete (RC) structures, which utilize steel bars for reinforcement, are vulnerable to corrosion-induced deterioration. This degradation compromises material integrity and diminishes structural longevity. Over the past decade, Fiber Reinforced Polymer (FRP) bars have emerged as a corrosion-resistant alternative to steel, offering superior tensile strength and lightweight properties. This study investigates the shear response behavior of RC beams reinforced with longitudinal and transverse FRP bars through simplified formulations and comprehensive numerical analyses. An extensive database of experimental tests from the literature was compiled, encompassing a wide range of key parameters, including cross-sectional geometry and stirrup quantity. Numerical results reveal that FRP-reinforced beams exhibit distinct structural responses compared to their steel-reinforced counterparts, including notable variations in deflection characteristics and load-bearing capacity. These findings contribute to a deeper understanding of FRP-reinforced concrete behavior and have significant implications for the design and implementation of corrosion-resistant structural elements in challenging environments.
