To solve a problem in a conventional seismic isolation structure in which a response acceleration y can be reduced when a vibration system of a long period (low frequency) is made, and as a result, a response deformation y is considered that there is no help when no matter how large it becomes, and therefore a large-scale laminated rubber bearing is developed to thereby increase the cost of the isolation structure.MEANS FOR SOLVING THE PROBLEM: In an isolation structure supporting a construction by a laminated rubber bearing, the lateral stiffness and the damping coefficient of the laminated rubber bearing are set so that a ratio of the primary natural angular frequency ωof the construction to the primary natural angular frequency ωof the isolation structure may satisfy 0.65<ω/ω<0.75.SELECTED DRAWING: Figure 1
【課題】長周期（低振動数）の振動系を作ると、応答加速度yが低減できるからである。結果として、応答変形yは、幾ら大きくなっても仕方がないものと考えられていたのである。そのため、大型の積層ゴム支承が開発され、免震構造のコストは増大することとなった。【課題手段】構造物を積層ゴム支承で支持した免震構造において、前記構造物の1次固有角振動数ω1と、前記免震構造の1次固有角振動数ωeqとの比率が、０．６５＜ωeq／ω1＜０．７５を満足するように、積層ゴム支承の水平剛性と減衰係数とを設定した。【選択図】図１
