Abstract- The structures constructed with good techniques and machines in the recent past have fallen prey to earthquakes leading to enormous loss of life and property and untold sufferings to the survivors of the earthquake hit area. Base isolation concept was coined by engineers and scientists as early as in the year and thereafter different methods of isolating the buildings and structures from earthquake forces have been developed world over. Controlling seismic behaviour is possible only through faithful design that ensures all behavioural actions considered in buildings during analysis. In keeping with the key characteristics of buildings, structural design of buildings can be stiffness-based, strength-based, deformation-based and energy- based. In this paper a review has been done for the base isolated structure with different techniques, parameters and components. The destruction caused by an earthquake is highly unpredictable and sometimes beyond repair.

Base Isolation System: A Review | Semantic Scholar
The design of a structure or mechanism subjected to shock and vibration can be greatly improved by the addition of isolation or damping devices. This paper reports on a non-linear analysis of a bridge supported on sliding bearings with elastomeric restoring spring and viscous dampers. Results were verified with shake table tests. This document shows designers how to avoid corrosion due to the interaction of different metals and alloys at bimetallic contacts. Section one describes the conditions that lead to corrosion at bimetallic contacts and methods to alleviate it. The tables in Section two show the degree of corrosion likely to occur at bimetallic contacts exposed to atmosphere and water. Taylor Devices, Inc.
Seismic base isolation
Earthquake produce surface waves, which cause vibration of the ground and structures standing on top. Depending on the characteristics of these vibrations, the ground may develop cracks, fissures and settlements. The possible risk of loss of life adds a very serious dimension to seismic design. In recent times, many new systems have been developed, either to reduce the earthquake forces acting on the structure or to absorb a part of seismic energy.
Seismic base isolation , also known as base isolation ,  or base isolation system ,  is one of the most popular means of protecting a structure against earthquake forces. Base isolation is one of the most powerful tools of earthquake engineering pertaining to the passive structural vibration control technologies. The isolation can be obtained by the use of various techniques like rubber bearings, friction bearings, ball bearings, spring systems and other means.
