Abstract: The main objective of project is to compare conventional Seismic analysis and lead rubber bearing system. While no structure can be entirely immune to damage from earthquakes, the goal of earthquake resistant construction is to erect structures that fare better during Seismic activity than their conventional counterparts. The installation of isolators at the base increases the flexibility of the building structures. In present study Modeling and analysis of G+10 storey RC building is done in ETBS software for two cases. The first one is fixed base and the second one is base isolated; one vertical irregular model is considered and analysis is done by equivalent static and response spectrum method. The Lead rubber bearing (LRB) is designed as per IS and UBC 97 code and the same was used for analysis of base isolation system. The results obtained from analysis were Storey displacement. Damper systems are designed and manufactured to protect integrities and structural damages and to prevent injuries. There are many techniques to make seismic resistant structure. The base isolation technique is used in this project to resist against earthquake. Lead Rubber Bearing is a new type earthquake resistance rubber bearing, formed by inserting lead core into ordinary laminated rubber bearing, vertical supporting, and horizontal displacement and hysteric damping are combined in single unit together.
