ASEISMIC ISOLATION STRUCTURE
To provide an aseismic isolation structure to effectively reduce vertical vibration.SOLUTION: An aseismic isolation structure is provided with a vertical damping device, the vertical damping device placed in an aseismic layer between an upper structure and a lower structure being configured to damp vibration created by tension and compression in a vertical direction which connects its upper end to the upper structure and its lower end to the lower structure, wherein a damping force generated with a relative displacement created by movements of the upper end and the lower end at a predetermined speed in a tension area is larger than a damping force generated with a relative displacement created by movements of the upper end and the lower end at a predetermined speed in a compression area.SELECTED DRAWING: Figure 5
【課題】上下方向の振動を効果的に低減する。【解決手段】上部構造と下部構造との間の免震層に、上端が上部構造に接続され、且つ、下端が下部構造に接続されて上下方向の引張と圧縮の振動を減衰する上下減衰装置であって、引張領域において上端と下端が所定速度で相対変位するときに発生する減衰力が、圧縮領域において上端と下端が所定速度で相対変位するときに発生する減衰力よりも大きい上下減衰装置を備える。【選択図】図５
