A large proportion of world‟s population lives in regions of seismic hazards, at risk from
earthquakes of varying severity and frequency of occurrence. Earthquake causes significant loss of life and
damage of property every year. So, to mitigate the effect of earthquake on building the base isolation
technique one of the best solutions.
Seismic isolation consists of essentially the installation of mechanisms which decouple the
structure from base by providing seismi isolators. The seismic isolation system is mounted beneath the
superstructure and is referred as „Base Isolation‟.
