Seismic Strengthening of Existing RCC Structure by FRP Jacketing

Abstract

India has been facing many disasters since long. Among the entire disasters earthquake is of serious concern to Civil Engineers. Because of collapse of structures subjected to seismic loads many lives were lost because these buildings were not designed for seismic loads. The problem becomes more serious when additional storeys are constructed. In these buildings many of the columns are not safe if the building is analyzed for seismic load. To make the building safe we need to adopt the technique of FRP (Fiber Reinforced Polymer) jacketing. The FRP Jacketing is comparatively better than other retrofitting because no major strengthening of foundation is required in this technique, also original function of the building can be maintained without any major change in the original geometry of the building. The present study is on a four storey building that has been planned in STAAD.ProV8i, considering M30 cement and Fe415 steel bars.
