SEISMIC ISOLATION STRUCTURE AND SEISMIC ISOLATION DEVICE
To provide a seismic isolation device excellent in buckling performance and durability without impairing required seismic isolation performance.SOLUTION: A seismic isolation structure 10 is formed by alternately arranging hard material layers 11 and soft material layers 12. The seismic isolation structure 10 has a constricted part R2. A ratio Rw of a width W2 of the constricted part R2 to a width W1 of the seismic isolation structure 10 is within a range of 0.7≤Rw≤0.825. A ratio Rh of a height H2 of the constricted part R2 to a height H1 of the seismic isolation structure 10 is within a range of 0.6≤Rh≤0.8. A seismic isolation device 1 comprises the seismic isolation structure 10 and two plates 20 arranged at both ends of the seismic isolation structure 10.SELECTED DRAWING: Figure 1
【課題】要求される免震性能を損なうことなく、座屈性能及び耐久性に優れた免震装置を提供する。【解決手段】免震構造体10は、硬質材料層11と軟質材料層12とを交互に配置してなる。免震構造体10は、くびれ部R2を有している。免震構造体10の幅Ｗ１に対する、くびれ部R2の幅Ｗ２の比Ｒｗは、０．７≦Ｒｗ≦０．８２５の範囲内にある。免震構造体10の高さＨ１に対する、くびれ部R2の高さＨ２の比Ｒｈは、０．６≦Ｒｈ≦０．８の範囲内にある。免震装置1は、免震構造体10と、免震構造体10の両端に配置された、２つのプレート20と、を備える。【選択図】図１
