Abstract
The present work attempts to study the effectiveness of base isolation using lead rubber bearings (LRB) over conventional construction, using a case study of identical conventional and isolated building constructed in the most seismically active region in India (Zone V). Base isolators protect both structural and non-structural components by separating a superstructure from its substructure that is resting on a moving surface. In this study, two cases of G+9 plane symmetrical RCC frames are modelled and analyzed. First, a fixed base, and second, an isolated base (LRB). For both scenarios, building displacement is compared.. For analysis ETABS software is use and for designing of isolator 1893:2002 (part 1) and UBC 97 design of seismic isolated structures.
