This paper describes about earthquake response of high-rise building where vibration control system is applied. The vibration control system is a kind of tuned liquid damper, using resonance of water sloshing in a U-shaped water tank whose natural period is adjusted to that of the main structure. The authors have developed and applied the device to full scale structures, clarified the vibration characteristic of the device from the ambient vibration of the building and from the numerical analysis, and illustrated the effect of the device by the wind and the seismic observation. In this paper, the earthquake observation result in a building where the device is applied is simulated using the multi degree of freedom model including the nonlinear damping, and the accuracy of modeling is verified. In addition, reduction of response by the device is quantitatively evaluated by simulating the response of a building where the device is not applied.
