1. Motivation Seismic isolation and energy dissipating systems present an effective way to common seismic design for improving the seismic performance of structures. These techniques reduce the seismic forces by changing the stiffness and/or damping in the structures, whereas conventional seismic design is required for an additional strength and ductility to resist seismic forces.

2. Research Field Various kinds of devices are used in the buildings for the purpose of seismic isolation. It would be useful to examine the seismic isolation in the framework of the basic principles of dynamics before introducing these devices.

Seismic isolation in a building, when considered within the framework of basic principles of dynamics, can be maintained by taking under the control, modifying and changing the characteristics of both restoringforce when affected by seismic forces, and damping of the building, and also the mass of the building and seismic forces that affect the building.

The purpose of earthquake prevention of buildings is to provide the structural safety and comfort by controlling the internal forces and displacement within the particular limits. The common method for protecting the structures against the destructive effects of earthquakes is to damp the seismic energy for limiting the seismic energy by the structural elements, thus providing the resistance against the earthquake. In spite of using this method for a certain level of protection, the structure could be damaged for real sometimes.
