Strengthening and Retrofitting of RC Beams Using Fiber Reinforced Polymers

Reinforced Cement Concrete (RCC) Structures are bound to lose its strength while in service due to various causes. Rehabilitation restores the health and service life of the structures. Fiber Reinforced Polymer (FRP) composites overcome most of the limitations of conventionally practiced repair techniques.The Fiber Reinforced Polymer (FRP) application is a effective method to repair and strengthen structures that have become structurally weak over their life span. FRP repair systems provide an economically viable alternative to traditional repair systems and materials. Among the various fibers, Glass Fibers (GF) is widely used in FRP. Strengthening of RC structural elements using externally bonded GFRP composite is an effective method to increase the structural performance under both service and ultimate load conditions. Restoring or upgrading the strength of beams using GFRP sheet can result in increased strength and stiffness.
