This report describes about new vibration control system using resonance of water sloshing in a U-shaped water tank whose natural period is adjusted to that of the main structure. One challenging issue is to control the structural responses in both horizontal directions with a single water tank. This paper proposes a design formula for calculating the natural period of the system by examining the measured results of devices installed in an office building. The damping effect of water sloshing, including fluid resistance of the water tank and supplemental damping devices submerged in the tank, is also examined analytically. Finally, advantage on the system is confirmed using observed response of actual building with earthquake and strong wind.
