Application of Tuned Mass Damper in Structures under Seismic Excitation ? A Review

Tall Buildings are increasing day by day and one cannot have count of the number of low rise to high rise buildings built in the world. As safety of the Occupants is the prime factor of importance the structural stability and reliability has been the foremost concern of Civil and Structural Engineers. Most of the structures are found to have very low natural damping. In order to increase the damping capacity of a structure various mechanical means to increase damping are being considered in the era of high rise buildings. Structural vibrations produced by earthquake or wind can be controlled by different methods such as masses, damping, rigidity or shape and by providing active or passive counter forces. This paper makes an attempt to understand the present knowledge on Tuned Mass Damper in structural systems and their applications in earthquake engineering. The research work done by various researchers and their conclusions have been discussed in detail.
