［摘要］疊層橡膠支座是隔震技術(shù)關(guān)鍵因素之一，研發(fā)了一種串聯(lián)型變剛度疊層橡膠隔震支座。該串聯(lián)型變剛度疊層橡膠隔震支座初始階段提供較小水平剛度（小于串聯(lián)型變剛度疊層橡膠隔震支座中較小直徑支座的剛度）。當(dāng)水平剪切變形達(dá)到設(shè)計目標(biāo)時，通過限位裝置提供第二剛度，使其出現(xiàn)較大變形時具有較大的大水平剛度。通過足尺支座試驗，研究了該串聯(lián)型變剛度支座的豎向性能、水平性能和滯回性能，并給出了該串聯(lián)型變剛度支座的計算模型。

Abstract:Laminated rubber bearing is one of the key factors of isolation technology. A series type laminated rubber bearing with variable stiffness was developed. The initial stage of the series support provides a small horizontal stiffness (less than the stiffness of the smaller support in the series support). When the horizontal shear deformation reaches the design goal, the second stiffness was provided by the limit device, so that it has a larger horizontal stiffness when there is a larger deformation. Through the full-scale bearing test, the vertical performance, horizontal performance and hysteretic performance of the series variable stiffness bearing were studied, and the calculation model of the series variable stiffness bearing was given.
Keywords:isolation technology; laminated rubber bearing; series connection type; variable stiffness
