Applied mechanics Materials of engineering and construction Reinforced concrete Retrofitting of concrete elements is one of the methods among numerous other methods in extending the lifespan of the structural members without undergoing the process of redesigning and reconstructing.

Hence to avoid, there are various types of repairing tools, materials and techniques have been developed over time depending on type of damages and how severe the damages are.

The effectiveness of this method were measured through Load-Displacement Relationship between controlled specimen and the retrofitted specimen with addition on Energy Loss analysis of before and after retrofitting work.
