BASE ISOLATION DEVICE AND BASE ISOLATION METHOD
PROBLEM TO BE SOLVED: To provide a base isolation device and base isolation method capable of absorbing falling impact force of a structure even in a case of receiving unexpectedly large long-cycle earthquake motion to the structure.SOLUTION: A base isolation device 3 installed between a structure 12 and a foundation floor 1 includes: a support plate 6 opposite to the structure with a predetermined interval; a base plate 4 fixed to the foundation floor; and an elastoplastic damper 8 installed between the support plate and the base plate, and fixed to the support plate and the base plate. The elastoplastic damper includes an inner cylinder 5 and an outer cylinder 7 sliding mutually, and an elastoplastic member 14 provided inside the inner cylinder.SELECTED DRAWING: Figure 1
【課題】構造物に対して想定外の大きな長周期地震動を受けても、構造物の落下衝撃力を吸収できる免震装置および免震方法を提供する。【解決手段】構造物１２と基礎床１との間に設置される免震装置３において、前記構造物と所定の間隔を設けて対面する支持プレート６と、前記基礎床に固定されるベースプレート４と、前記支持プレートと前記ベースプレートとの間に設置され、前記支持プレートおよび前記ベースプレートに固定される弾塑性ダンパー８とを備え、前記弾塑性ダンパーは、互いに摺動する内筒５および外筒７と、前記内筒内部に設けられた弾塑性部材１４とを備える。【選択図】図１
