PERFORMANCE OF RC BUILDING UNDER DYNAMIC FORCES AND SUITABILITY OF STRENGTHENING BY FRP JACKETING

In the recent years it has been observed many mass destruction due to earthquakes which results into loss of lives also. Therefore, it is of great importance that attention to be given to the evaluation of the adequacy of strength in RC framed structures to resist strong ground motions. In this project, a 15 year old four storey reinforced concrete structure has been considered, which lies in Zone III according to IS 1893:2002 classification of seismic zones in India. FRP jacketing is a most appropriate method of retrofitting for the failing members in the given G+3 storied RC structure. The norms stated in ACI 440-2R.08 have been followed for calculations and to suggest the method and scheme of application of FRP’s to the member and also the number of plies/wraps to be used. The entire modelling, analysis and design for the structure has been done using limit state design.
