Development of Active-Damping Bridges and Its Application to Triple High-Rise Buildings

抄録

The X-, Y- and Z-Tower office buildings of the Harumi Island Triton Square are located very close to one another. The distance between two of the three towers is as narrow as 13 meters. To increase the habitability of these buildings when they vibrate during a strong wind, they are equipped with active-damping bridges. Each active-damping bridge connects one building to another and actively controls expansion and contraction to reduce vibrations. In this paper, a general description of the buildings and equipment will be presented, following which an applied control system design method will be related. The paper will conclude with a report of tests on the actual buildings conducted to verify performance.
