ABSTRACT Earthquakes cause severe damage to property, especially to man-made structures and necessitate architects and engineers with a number of important design criteria foreign to the normal design process. As many researchers studied and reviewed that seismic isolation is the better solution for the earth quake resistant design of the structures and its application is the most constructive technique to protect structures against vandalization from the earth quake strike and has gained growing majority during past decades .This is because base isolation confines the effects of the earthquake strike, a workable base largely separating the structure from the ground motion, and the structural counter accelerations are usually less as compared to the ground acceleration. The present work is intended to provide a systematic procedure to assess the behavior of a structure during the seismic excitation. In this work, a lead rubber bearing isolator is used from low to high rise RC buildings [1] by doing Time History Analysis. The fundamental goal of base isolation is to reduce substantially the absorption of the earthquake induced force and energy by the structure. This is accomplished by placing a structure on a support mechanism with low lateral stiffness so that in an event of earthquake, when the ground undergoes strong motion, only moderate motion is induced in the structure itself. Base isolation system significantly reduces the super structure lateral stiffness and ductility compared to un-isolated structure which is demonstrated by the results of this work. This allow cost saving from less material being spend on lateral system and implication of structural detailing. Key words: Time History Analysis, Lead Rubber Base Isolator, ETABS.
