| During recent years, the use of fiber-reinforced polymers (FRP) as a desirable alternative for improving the behavior of lateral resisting system are known. There are various factors influencing the quality of such kind of rehabilitation. This study aims to investigate the influence of geometric characteristics and arrangement of FRP layers on rehabilitating of concrete shear walls. A few reinforced concrete shear walls with different thickness and arrangement of FRP layers were analyzed by ABAQUS finite element model software, under gravity and lateral loads. The results indicated that the variation of shear wall strength is considerable due to confinement provided by the FRP layers based on the influence of thickness and arrangements. It is seen that, the performance of Chess and Cross layers of FRP are more effective than other arrangements for improving the final strength of reinforced concrete shear wall. It is also observed that, by increasing the FRP thickness, the wall performance against lateral loading will be improved considerably. | ||
