Abstract : When the Earthquake comes there is a huge force acts on the earth surface. The soil influences the motion of structure and the motion of structure influences the response of soil. Due to the earthquake forces, displacement occurs in the structure which consequently causes the huge damage to the structure. In order to minimize the damage which is caused by the earthquake we use seismic isolation devices. Seismic isolation devices absorbs or minimize the shock in the structure arises from earthquake. Seismic isolation devices reduce the stiffness or damping in the structure. Seismic isolation devices mounted between the foundation and floor of the structure. Seismic isolation device decreases the base shear and displacement but increases the floor acceleration and interstorey drift. In this research paper we study about different type of seismic base isolator and its mechanism. There are two basic type of isolator (Elastomeric bearing and Friction pendulum bearing) and some supplementary devices. The main goal of this research paper is to minimize the damage which occurs due tothe earthquake with the help of seismic isolation devices.
