InPresentday,thetallBuildingconstructionsareincreasingday-by-day.Recentlytheconstruction industry demands easy, economical, sustainable structures, which are more flexible,light in weight and having low damping value. The probability of failure is increases because oflower damping due to which vibration of building increases. To reduce the dynamic response ofstructure, it become important for structure consumes or dissipated this energy. There are varioustechniquesareusedtodecreasevibrationofstructureandthestructuralsystemhavebeenmodified with the use of mechanical means. Since mechanical means are the part of energydissipationsystem in thebuilding.

Passive control devices which imparts force that is developed in response to the motion of thestructure by absorbing some of the input energy, it reduces the energy dissipation demand on thestructure. Therefore no external power source is required to add energy to the structural system.Passive energy dissipating devices such as the metallic dampers, friction dampers, viscos-elasticdampers and fluid viscous dampers are in use, amongst fluid viscous dampers (FVDs) are foundto have desirable performance to control shock loads. These devices the motion of structure iscontrolledbyaddingdevices to thestructurein theform of stiffness and damping
