LONG-PERIOD EARTHQUAKE CORRESPONDING VIBRATION CONTROL BUILDING
To provide a high-rise vibration control building which includes a vibration control device having a high vibration control effect with respect to a normal short-period earthquake vibration and capable of suppressing resonance by a long-period earthquake vibration.SOLUTION: Between a ceiling and a floor of a building unit of each layer of a high-rise building, an attenuation force generation type damper (a vibration control device A) is mounted, and an attenuation force and inertia force generation type mass damper (a vibration control device B) is mounted via a one-dimensional rattling generation mechanism 7 (or a two-dimensional rattling generation mechanism 9). Thereby, when receiving a normal short-period earthquake vibration, the vibration control device A actuates and suppresses the vibration of the building, and when receiving a long-period earthquake vibration and the building resonates, the vibration control devices A and B actuate together and suppress the resonance.SELECTED DRAWING: Figure 1
【課題】通常の短周期地震動に対する制震効果が高く、且つ長周期地震動による共振を抑制できるような制震装置を備えた高層制震建物を提供すること。【解決手段】高層建物各層の建物ユニットの天井と床の間に、減衰力発生型ダンパー（制震装置Ａ）を取り付け、且つ一次元ガタ発生機構７（又は二次元ガタ発生機構９）を介して減衰力及び慣性力発生型のマスダンパー（制震装置Ｂ）を取り付けた。これにより、通常の短周期地震動を受けた時は制震装置Ａが作動して建物の揺れを抑制し、長周期地震動を受けて建物が共振した時は制震装置ＡとＢが共に作動して、共振を抑制する。【選択図】図１
