Seismic hazards are a major concern in many populous regions of the world. Performance-based seismicdesign has brought about new technological advances and introduced an innovative approach to constructing seismicresistant buildings. Base isolation is one of the most powerful tools of earthquake engineering pertaining to the passivestructural vibration control technologies. The application of the base isolation techniques to protect structures againstdamage from earthquake attacks has been considered as one of the most effective approaches and has gained increasingacceptance during the last two decades.Design of base isolation bearing is taken from International Building code IBC2000In order to verify the effect of base isolation system, two different structures are presented (7 stories symmetricaland non-symmetrical school buildings) in which the seismic responses of the 'fixed-base' and 'base-isolated' conditionshave been compared using Etabs (a well-known computer program).The high damping rubber isolation system has beenused and devices have been installed at the foundation level. Response Spectrum Analysis has been performed usingIndian Standard Code IS-1893(Part-1):2002. Comparing the results of the base-isolated condition with those obtainedfrom the fixed-base condition has shown that the base isolation system reduces the base shear force and storey drifts,whilst also increasing the displacement.
