LONG-PERIOD EARTHQUAKE COPING BASE-ISOLATION BUILDING
PROBLEM TO BE SOLVED: To provide a base-isolation building having the high base-isolation effect to ordinary short-period earthquake motion, and capable of restraining resonance caused by long-period earthquake motion.SOLUTION: In addition to an ordinary base-isolation device composed of laminate rubbers 3 to 6 and a damper (unillustrated), additional laminate rubbers 8 to 11 for imparting a gradually curable restoring force characteristic and additional dampers 16 to 19 for imparting a gradually curable damping force characteristic, are installed between a building foundation part 1a and a floor 2 via looseness generation mechanisms 12 to 15. Thus, in short-period earthquake motion time, the base isolation effect is imparted by operating only the ordinary base-isolation device, and a building 1 resonates by long-period earthquake motion, and when vibrating by exceeding looseness, additional laminate rubber and damper operate in addition to the ordinary base-isolation device, thereby restraining resonance.SELECTED DRAWING: Figure 5
【課題】通常の短周期地震動に対する免震効果が高く、且つ長周期地震動による共振を抑制できるような免震建物を提供すること。【解決手段】積層ゴム３乃至６とダンパー（図示せず）から成る通常の免震装置に加えて、漸硬型復元力特性を与えるための追加の積層ゴム８乃至１１と、漸硬型減衰力特性を与えるための追加のダンパー１６乃至１９を、ガタ発生機構１２乃至１５を介して建物基礎部１ａと床２の間に取り付けた。これにより、短周期地震動時には、通常の免震装置のみが作動して免震効果を与え、長周期地震動により建物１が共振し、ガタを超えて振動した時には、通常の免震装置に加えて追加の積層ゴムとダンパーが作動し、共振を抑制する。【選択図】図５
