Retrofitting is modifying existing equipment's or structure with additional or new components or members. Which actually make the old structures more resistant to seismic activity. Retrofitting reduces the vulnerability of damage of an existing structures. Now days the use of retrofitting is expanding like a wildfire. Retrofitting helps to increase the strength, resistivity and overall life span of the structures. Its only aim to strengthen a structures again. As structures lose their strength with the period of time. Retrofitting is processes of adding new features to older buildings and weaker buildings. Retrofitting is best and economic option to make existing inadequate building safe against future hazards like-earthquake. It was also observed that retrofitting also helps in regaining the strength of the structure which lost its strength in fire. The normal concrete structure easily gained strength by wrapping FRP sheets in 2 or more layers. The strength can be further increased by increasing number of wrappings.
