  • Method of and apparatus for damping the vibration of a building
    Patent number: 5544452
    Abstract: A passive vibration-damping unit in which movable upper members with a weight mounted thereon are superposed on fixed lower members with roller members interposed therebetween is installed in a highest story of a high-rise building. An active vibration-damping unit for actively causing the movable upper members of the passive vibration-damping unit to move in a shaking manner by means of a servo motor is incorporated in the passive vibration-damping unit. When the vibration of the building has occurred, the weight is allowed to move forcibly in the vibration-damping direction by means of the active vibration-damping unit. When the vibration has reached a limit value of the relative displacement of the active vibration-damping unit or a limit value of the torque of the servo motor, only the operation of the passive vibration-damping unit is continued. When the vibration has subsided to a certain extent, the active vibration-damping unit is operated again.
