ANTIVIBRATION DEVICE AND ANTIVIBRATION STRUCTURE
PROBLEM TO BE SOLVED: To provide an antivibration device and an antivibration structure, which enable effective energy absorption.SOLUTION: An antivibration device 100 comprises: dampers 10 (a left upper damper 10a, a left lower damper 10b, a right lower damper 10c, and a right upper damper 10d) equipped with a plastically deformable steel pipe 11; and a laminate beam 20 having higher strength and stiffness than the steel pipe 11. A relative stiffness (r), which is ratio of beam stiffness obtained by dividing second moment of area of the laminate beam 20 by a distance between the dampers 10 to pipe stiffness obtained by dividing second moment of area of the steel pipe 11 by height of the steel pipe, is 10 or greater. Moment ratio (m), which is ratio of moment at a joint position with a laminate beam side end plate 12 fixed on the laminate beam 20 to the moment at a joint position with a support member side end plate 13 fixed to an upper support member 3a installed on an upper beam 2a or a lower support member 3b installed on a lower beam 2b, is 0.7 or greater.SELECTED DRAWING: Figure 1
【課題】有効なエネルギー吸収を可能にする制振装置および制振構造物を提供する。【解決手段】制振装置１００は、塑性変形可能な鋼管１１を具備するダンパー１０（左上ダンパー１０ａ、左下ダンパー１０ｂ、右下ダンパー１０ｃ、右上ダンパー１０ｄ）と、鋼管１１よりも高い強度および剛性を具備する積層梁２０とを有し、鋼管１１の断面二次モーメントを鋼管の高さで除した管剛性に対する、積層梁２０の断面二次モーメントをダンパー１０同士の距離で除した梁剛性の比率である剛比（ｒ）が１０以上で、上梁２ａに設置された上支持部材３ａまたは下梁２ｂに設置された下支持部材３ｂに固定された支持部材側エンドプレート１３との接合位置におけるモーメントに対する、積層梁２０に固定された積層梁側エンドプレート１２との接合位置におけるモーメントの比率であるモーメント比（ｍ）が０．７以上である。【選択図】図１
