Development of Connecting Type Actively Controlled Vibration Control Devices and Application to High-rise Triple Buildings

摘要

A new type of active vibration control system has been developed. The active-damping bridge connects one building to another, and actively controls expansion and contraction to reduce vibrations. The X, Y and Z Tower office buildings of the Harumi Island Triton Square, which opened in 2001, are high-rise triple towers of 195 m, 175 m and 155 m respectively, and are located very close to one another. With the view of increasing habitability during strong winds, the towers have been equipped with two units of this type. This system has achieved the designed damping performance through the functional test of single unit at the factory and excitation tests at the site.
