RETROFITTING OF OLD BUILDINGS THROUGH FRP

Abstract

Strengthening of concrete structures in flexure with externally epoxy-bonded fiber-reinforced plastic (FRP) laminates is becoming an increasingly popular retrofit technique among researchers and engineers worldwide. This has been due to both the needs for maintaining and upgrading essential infrastructure in all the parts of the world, and well known advantages of FRP composite including both corrosion resistance and ease for site handling due to light weight. Flexural Strengthening of RC beams using bonded FRP soffit plates has become popular over the last few years Plated reinforced concrete structures are a new and unique form of structure which has similar failure mechanisms or behaviours as in both reinforced concrete structures and composite steel and concrete structures.However plated structures also have many new failure mechanisms that are not covered in reinforced concrete and composite design manuals. FRP plated beams can fail in various modes, which can be broadly cl...
