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

In the recent past, India has seen mass destruction due to failure of structures hit by earthquakes and consequently, lost a lot of lives. Hence, it is of utmost importance that attention 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 Seismic Zone III according to IS 1893:2002 classification of seismic zones in India. For non-structural members masonry infill has been assumed. In the Equivalent Static Method of analysis, the seismic load acting on the structure is assumed to be an equivalent static horizontal force applied to individual frames. The total force applied shall be equal to the product of the acceleration response spectrum and the seismic weight. It is used only for low to high rise buildings without significant coupled lateral-torsional modes.
