A hybrid mass damper using a hydraulic actuator and a multistage rubber bearing was developed and implemented to the Long Term Credit Bank of Japan Building which has a 130m height, a 62,82lm■ total floor area, a 39,800t total weight. This mass damper can work mainly as an active one to effectively control relatively small vibrations of a building caused by winds and weak earthquakes. At the same time, it can work as a passive one against strong earthquakes. The moving mass has an outer size of 18 x 6.5 x 4.5■m and a 195t weight, and heat strage tanks are utilized as a part of it. The active-passive mode switching rules and a variable gain control law were adopted to make the mass damper perform more effectively against frequent winds and earthquakes. Excitation tests and simulations were carried out, showing that the mass damper continued the active mode throughout for strong winds and weak earthquakes, and that, for the strong earthquakes, the passive mode appeared for a period of the excitation with largacceleration, then the active mode resumed and effectively suppressed the residual vibration of the building. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
