Abstract
【課題】面圧60MPaを実現する摺動体を備えた高性能な滑り免震装置を提供すること。
【解決手段】曲率を有する摺動面1a,2aを備えた上沓1および下沓2と、上沓1と下沓2の間でそれぞれの沓と接して曲率を有する上面4aおよび下面4bを備えた柱状で鋼製の摺動体7と、から構成される滑り免震装置10であって、摺動体7の上面4aと下面4bは、PTFE繊維とPTFE繊維よりも引張強度の高い繊維からなる二重織物層5,6を、PTFE繊維が上沓1および下沓2の摺動面1a,2a側に配設されるようにして備えている。
【選択図】図1
Description
図1は本発明の滑り免震装置の実施の形態の縦断面図であり、図2は滑り免震装置の上沓を取り除いて斜め上から見た斜視図である。
本発明者等は、本発明の滑り免震装置(動摩擦係数μの基準値が0.045〜0.05)を製作し、この滑り免震装置に対し、60MPaの荷重を載荷した状態で、20℃で400mm/secの速度で繰り返し耐久試験を実施した。試験結果である、繰り返し回数120回までの各サイクル数と動摩擦係数の変動(測定値)を以下の表2と図5に示す。
本発明者等はさらに、固有周期の異なる種々の滑り免震装置をコンピュータ内でモデル化し、各滑り免震装置に対して、動摩擦係数ごとのせん断力係数と応答変位を検証する実験をおこなった。実験結果を図6に示す。
