In this paper, comparison is made between vibration control systems using viscous damper, viscous mass damper and tuned viscous mass damper. It is shown that the vibration control system using the viscous mass damper is the most effective for linear structural system with the dampers having same damping ratio. Effectiveness of the present vibration control system is verified conducting shaking table tests with small scaled tuned viscous mass dampers. And, applicability of the present vibration control system to non-linear structural systems subjected to seismic ground motions is also shown by performing non-linear time history analyses.
