Past study on earthquake prominently bring into notice that, earthquake protective structure isfalls notion. Only possible fact is to resistant vulnerable effects through control systems which limits the damage within permissible even under the greatest possible earthquake. There are many such systems available and serving the purpose from last two decade like passive, active and hybrid earthquake control systems. Passive control systems comprise base isolators, tuned mass damper etc. are most popular out of all. Base isolation is the most accepted member of the family due to its compatibility in hardware, applications, design codes and retrofit manuals. The most popular seismic isolation systems use elastomeric bearings which consist of rubber and steel plates with an energy dissipation mechanism. Common isolation systems in use today include elastomeric and sliding bearings with and without dampers or damping mechanisms. This review paper includes conceptual working principal, methodology, and types of available isolators. It also summarizes effect of different available isolator and their applicability on design parameters like storey drift, storeydisplacement, base shear and time period form literature. This study presents a comparative table of different parameters such as frequency, base shear, displacement, and story drift with and without base isolation from literature. Keywords.

Introduction 1.1 Earthquake A disturbance that causes shaking of the earth's surface due to movement underground along a fault plane or from volcanic activity is called an earthquake [19]. The primary destructive effects of earthquakes are landslides, tsunamis, liquid fluorescence, and ground shaking. But the first and most obvious sign of earthquakes is ground shaking. Out of all the destructive effects of an earthquake, ground shaking has the most effect miles away from the epicentre, depending on magnitude. Ground waves generated by earthquakes are sudden and erratic in nature. This ground motion was transferred to the structure through the foundation resting on it. During an earthquake, each structure oscillates with its natural frequency, depending on its stiffness, mass, and height. But the effect is violent if the frequency of the building matches the earthquake frequency and it is vulnerable to collapse due to ground motion. This issue can be mitigated by three measures, as shown in Figure 1. 1.2 Base Isolation There are prominently three systems: passive, active, and hybrid earthquake control systems, which can control the effects of earthquakes within an acceptable level. But due to their compatibility with software, passive systems are perhaps the best known. Passive control systems, such as base isolators, tuned mass dampers, etc., have had a wide range of applications over the past few decades, such as seismic control, retrofitting, etc. [2].
