VIBRATION CONTROL BUILDING AND BUILDING VIBRATION CONTROL METHOD
PROBLEM TO BE SOLVED: To provide a mass damper type vibration control system which exerts a vibration control effect on vibration not only in a primary mode but also in higher modes.SOLUTION: A vibration control building 10 comprises: a building 20 as a vibration control object; an external structure 30 which is arranged along a periphery 20A of the building 20, with an upper section thereof supported by the building 20 in a manner that allows the external structure 30 to have a relative displacement with respect to the building 20 in horizontal directions through bearings 50 having restoring force in the horizontal directions and a lower end thereof separated from a foundation 1 of the building 20 in a manner that prevents a foundation 1 of the building 20 from direct input of earthquake force, and functions as a mass damper for the building 20; and a plurality of vibration control dampers 40 connecting the building 20 and the external structure 30 on a plurality of levels so that respective vibration control dampers 40 deform in accordance with relative displacements therebetween to absorb vibration energy of the building 20.
【課題】１次モードの振動のみならず、高次の振動モードに対しても制振効果を発揮するマスダンパー型の制振システムを提供する。【解決手段】制振建造物１０は、制振対象の建物２０と、建物２０の外周２０Ａに面して配され、上部は建物２０に水平方向への復元力がある支承５０を介して水平方向に相対変位可能に支持され、下端は建物２０の基礎１に対して地震力が直接入力しないように縁が切られており、建物２０に対してマスダンパーとして機能する外部架構３０と、建物２０と外部架構３０とを複数層において連結し、建物２０と外部架構３０との相対変位に応じて変形して建物２０の振動エネルギーを吸収する複数の制振ダンパー４０とを備える。【選択図】図５
