  7. Abstract:
  8. Shear wall has been widely used in RC structures due to high initial stiffness and lateral load capacity. Hence, the behavior and effectiveness of retrofitting technique on shear wall are needed to be investigated widely. Among several available techniques for retrofitting RC structures, fiber reinforced polymer (FRP) is quite effective because of its high strength-weight ratio, high resistance to corrosion and easy handling and installation. Several researchers have investigated on the behavior of retrofitted RC members with FRP jackets like columns. However, application of FRP laminates on RC walls has attracted less attention by researchers. In this study a numerical investigation on rehabilitating reinforced concrete squat shear wall using fiber reinforced polymer (FRP) was performed. The FRP laminates were applied on shear walls in order to improve hysteretic response characteristics. Comparison between numerical results and experimental data indicated the adequacy of the numerical approach. In addition, influence of some parameters such as effect of anchor system, FRP layers numbers, the percentage of horizontal shear reinforcement, the percentage of vertical shear reinforcement and the percentage of vertical reinforcement in the boundary elements were investigated. It has been shown that these parameters have significant effect on shear wall behavior
