A comprehensive study of the effect of fiber reinforced polymer (FRP) on the shear strength and seismic behavior of shear walls: A review of experimental and analytical studies

Shear walls are vital components that provide resistance against lateral loads in reinforced concrete buildings structures. Due to their susceptibility to seismic activity, implementing effective strengthening techniques, such as fiber reinforced polymer (FRP), has been suggested as a viable alternative to conventional methods. This analysis examined the influence of Fiber Reinforced Polymer (FRP) on the shear strength and seismic performance of shear walls by conducting an extensive review of both experimental and analytical studies. Research findings indicate that the reinforcement of shear walls using FRP enhances shear strength, minimizes lateral displacements, boosts ductility, and elevates energy absorption capacity. Research conducted in laboratory settings demonstrates that the characteristics of the fibers, their bonding methods, and the surface area of the FRP coating play a crucial role in determining the seismic performance of the wall. Furthermore, numerical models utilizing the finite element method have effectively replicated the actual performance of reinforced shear walls with a high degree of precision, indicating the most effective strengthening configurations. The results of this study suggest that fiber-reinforced polymer (FRP) serves as a lightweight, durable, and cost-effective option for enhancing the seismic performance of shear walls. To attain an optimal design, it is advisable to conduct additional research on the durability of materials used for long-term performance, as well as the synergistic effects of fiber-reinforced polymer (FRP) in conjunction with other strengthening techniques.
