SEISMIC EVALUATION OF EXISTING STRUCTURE Abstract
Buildings are planned following code standards, satisfying all of the code\'s particular criteria and assuming that structural parts would behave in a linear elastic manner. Furthermore, it is vital to understand the behaviour of buildings built to earlier regulations or that were not meant to withstand earthquake pressures. Natural disasters are known to strike the world from time to time, posing a major hazard. The repercussions of earthquake reoccurrence, in particular, include the loss of human lives and the damage of property, both of which impact the natural economy. Because earthquakes cannot be foreseen or avoided, the ability of buildings to withstand seismic forces becomes more crucial. This thesis attempts to examine the performance of a typical chosen R.C. building regarding seismic vulnerability, keeping in mind the ongoing revision of the seismic zones in India and the lack of suitable design and detailing of buildings against earthquakes. For this seismic evaluation, a linear static has been performed by software ETABS considering material modification factor (Knowledge factor, K) FEMA 154. The analysis results showed the performance levels, the components\' behaviour, and the building\'s failure mechanism. It also showed the failure concerning the concrete deterioration of the existing buildings. Based on the analysis retrofitting is done by considering shear walls at different positions of the building, and the result has been compared with a term of story displacement, story drift, time periods, base shear and area of steel, and several columns failure with Knowledge factor.
