Abstract:

To provide a vibration-damping building equipped with a mass damper that can store water and suppress deterioration of seismic performance due to use of water.SOLUTION: In a vibration damping building 1 provided with a mass damper 10 on an upper layer, the mass damper 10 includes a water tank 20 having a plurality of water storage tanks 21 capable of discharging water, sliding bearing units 30 supporting the water tank 20, and a damping device 40 that attenuates vibration of the water tank 20. The sliding bearing units 30 includes first spherical sliding bearings 31 and second spherical sliding bearings 32 having a greater friction coefficient than the first spherical sliding bearings 31. When discharging water from the water tank 20, response displacement is adjusted according to the change in mass of the water tank 20 by discharging the water storage tanks 21 installed above the second spherical sliding bearing 32 before discharging the water storage tanks 21 installed above the first spherical sliding bearing 31.SELECTED DRAWING: Figure 1
