VIBRATION SUPPRESSION DEVICE FOR STRUCTURE
To provide a vibration suppression device for a structure capable of preventing excessive interlayer deformation of a structure even when damping performance of a damping wall is reduced.SOLUTION: A vibration suppression device 10 of a structure is provided with a damping wall 11 connected between a lower beam 5 and an upper beam 5. The damping wall 11 includes: a metal storage wall 14 formed in a box-like shape that is open upward, and having a lower end connected to the lower beam 5; a metal inner wall 15 formed in a plate shape, having an upper end connected to the upper beam 5 and inserted through the opening into the storage wall 14, and arranged at a distance from the inner surface of the storage wall 14; and a viscous body 16 filling the interior of the storage wall 14 and existing between the inner surface of the storage wall 14 and the inner wall 15. The vibration suppression device 10 further includes a pair of stoppers 12, 12 provided to face the storage wall 14 at a predetermined distance in a state of being connected to the upper beam 5 and hanging down on both sides of the damping wall 11, for suppressing the relative displacement between the lower beam 5 and the upper beam 5.SELECTED DRAWING: Figure 1
【課題】制震壁の減衰性能が低下した場合でも、構造物の過大な層間変形を防止することができる構造物の振動抑制装置を提供する。【解決手段】下側の梁５と上側の梁５との間に連結された制震壁１１を備えた構造物の振動抑制装置１０であって、制震壁１１は、上方に開口する箱状に形成され、下端部が下側の梁５に連結された金属製の収容壁１４と、板状に形成され、上端部が上側の梁５に連結されるとともに収容壁１４に開口を介して挿入され、収容壁１４の内面との間に間隔を存した状態に配置された金属製の内壁１５と、収容壁１４の内部に充填され、収容壁１４の内面と内壁１５の間に存する粘性体１６と、を有しており、上側の梁５に連結されかつ制震壁１１の両側に垂下した状態で、収容壁１４と所定間隔を隔てて対向するように設けられ、下側の梁５と上側の梁５との相対変位を抑制するための一対のストッパ１２、１２を、さらに備えている。【選択図】図１
