        abstract = {During the last few decades world has witnessed several devastating earthquakes, results in the loss of property of life thus putting a great moral responsibility on structural engineers to build the structure in such a way that they can withstand during the most severe earthquakes. Traditionally the structures were designed by increasing the stiffness of the structure or to make the structure flexible enough to reduce the impact of forces induced on the structure during earthquake which results in increase of peak floor acceleration or increase in inter storey drift values of the structure respectively and hence makes it difficult in insuring the safety of the structure and its non structural components.
Various studies have been performed in the past few years to minimize the damages caused by earthquake forces/ vibrations to the structure as well as non structural components of a RCC structure. The outcome of these studies is the use of various types of passive, active and hybrid control systems in which the base isolation is one of the passive control system by using lead rubber bearing isolators, friction pendulum, tuned mass dampers, tuned liquid dampers and elastomeric isolators. The concept of base isolators is to increase the flexibility of the structure at the base in both the orthogonal horizontal directions.
The intent of this paper is to study the effectiveness of the lead rubber isolator for G+15 storey RCC framed structure. The structure is analyzed in ETABS software using Bhuj earthquake data for two cases; one is for rigid jointed framed RCC structure and second is by the introduction of lead rubber bearing (LRB) isolators under the most seismically active region in India i.e. in zone V resting on loose soil (type III). The effectiveness of an isolator is demonstrated by comparing the storey drift, lateral displacement of the structure, base shear, acceleration and maximum bending moment of the fixed base structure to the isolated base structure.
Non-Linear time history analysis method is used to study the results.
