Abstract

Stability of a structure plays a vital role for economical and human loss during earthquakes, here base isolation is an approach mostly used for protecting structures from seismic forces. Base isolation is a interface system located between a structure and its foundation for the function of decoupling horizontal forces from earthquake ground motions, thereby reduce seismic damage to the structure and its contents. In this study we have designed lead rubber bearing (LRB) and friction pendulum system (FPS) type of isolators for G+9 RCC multistoried building in which modeling of G+9 building is carried out in ETABS 2016 as per IS 1893 (part 1) 2002 as per codal provisions. An equivalent static and time history analysis is done for fixed base, LRB, FPS isolators. Finally this reveals the seismic performance of building with different types of seismic base isolators by comparing the storey displacement, storey shear, storey drift and base shear.
