The strengthening of concrete structures externally bonded with fiber reinforced polymer (FRP) sheet is increasingly being used for repair and rehabilitation of existing structures. This paper provides information in the area of long-term durability of FRP-concrete interface externally bonded with FRP composite sheet. It mainly discusses and summarizes the influence of harsh environmental expos...

This research is devoted to investigate the behavior and performance of reinforced concrete beams strengthened with externally bonded Carbon Fiber Reinforced Polymer (CFRP) laminates under effect torsion. In this study a theoretical analysis has been conducted using finite element code ANSYS. Six previously tested are used behaviorunder torsion, two them solid rest box-section beams. Also, with...

Abstract The old existing RC structures around the world need to be examined and reinforced increase their capacity for different reasons. Fiber-Reinforced-Polymer (FRP) is believed most efficient system retrofit improve strength of members. However, in certain cases, engineers utilize combination flexural shear FRP systems, which was not mandated standard code. Therefore, this research focused...
