Strengthening and Retrofitting of RC Beams using Metal Wire Mesh

Large number of structures constructed in the past using older design codes are structurally unsafe. Replacement of deficient elements of structures are not acceptable because of huge cost and time consuming, strengthening can be suggested. Strengthening is the process of upgrading structure to improve performance under existing loads or to increase the strength of structural members to carry additional loads. In the situation to rectify distress in buildings and making it more suitable for intended use with enhancement of strength, Retrofitting can be suggested. Retrofitting is the process of modifying existing equipment or structures with additional or new components or members. Most commonly used techniques for strengthening and retrofitting is jacketing, bonding with external plates and wrapping. In order to replace uneconomical materials like CFRP, GFRP an attempt has been taken to replace them by metal wire mesh. This paper focuses on the usage of metal wire mesh for strengthening and retrofitting of concrete cylinders. M30 grade concrete is used in the investigation. Initial Tests on materials are carried out. The fresh and hardened property of concrete is also found. The enhancement in properties of cylinder due to the introduction of metal wire mesh is also studied.
