PROBLEM TO BE SOLVED: To provide a vibration damping structure capable of adapting to a large deformation and restricting occurrence of an excessive deformation.SOLUTION: A vibration damping structure comprises: a target structure for vibration damping; multiple first seismic isolation units, which are disposed in horizontal direction at intervals from each other on an apex of the target structure for vibration damping; spanning members, which are bridged between the first seismic isolation units; second seismic isolation units, which are stacked on the first seismic isolation units through spanning members; a mass body, which is supported by the first seismic isolation unit and the second seismic isolation unit; and either one of a first energy absorption mechanism, which restricts larger horizontal displacement than acceptable horizontal displacement of the first seismic isolation unit between the spanning member and the target structure for vibration damping, or a second energy absorption mechanism, which restricts larger horizontal displacement than acceptable horizontal displacement of the second seismic isolation unit between the spanning member and the mass body.SELECTED DRAWING: Figure 1
【課題】大きな変形に追随でき、且つ、過大な変形の発生を抑制することができる制振構造を提供する。【解決手段】制振対象の構造物と、制振対象の構造物の頂部に、水平方向に互いに間隔を隔てて配置された複数の第一免震ユニットと、複数の第一免震ユニット間に掛け渡された掛渡部材と、各々の第一免震ユニット上に掛渡部材を介してそれぞれ重ねられた第二免震ユニットと、第一免震ユニット及び第二免震ユニットに支承される質量体と、掛渡部材と制振対象の構造体との間にて第一免震ユニットの許容水平変位を超える水平変位を抑制する第一エネルギー吸収機構、及び、掛渡部材と前記質量体との間にて第二免震ユニットの許容水平変位を超える水平変位を抑制する第二エネルギー吸収機構のうちの少なくともいずれか一方と、を有している。【選択図】図１
