During an earthquake the principal attack on a structure is by horizontal force in different directions. The resistance of the structure against earthquake depends on elastic strength, inelastic deformability, damping capacity or a combination of all. In recent years there is a considerable research and development of structural control devices to control seismic response of buildings.
Many vibration-control measures like passive, active semi-active and hybrid has been developed. Dampers served as one of the most effective active systems. There are many types of dampers and based on that, their efficiency – effectiveness varies.

1) The incorporation of damping elements can often significantly improve performance.
2) The performance to cost ratio is more in structures where dampers are provided.
3) Dampers requires regular maintenance to work effectively.
4) The Damper technique effectively reduces stress on concrete and reinforcement.
5) Dampers can have isolation in all 6 degrees of freedom which the passive system cannot have.
