[提要]  分別以中國(guó)和日本生產(chǎn)的鉛芯橡膠支座作為隔震支座進(jìn)行振動(dòng)臺(tái)模型試驗(yàn)，對(duì)兩種隔震系統(tǒng)進(jìn)行了試驗(yàn)研究，同時(shí)進(jìn)行了基礎(chǔ)固定模型試驗(yàn)，對(duì)兩種基礎(chǔ)隔震模型與基礎(chǔ)固定模型的結(jié)構(gòu)反應(yīng)做了比較，并比較了兩種隔震系統(tǒng)的性能，結(jié)果表明兩種隔震系統(tǒng)均具有良好的隔震效果。中國(guó)生產(chǎn)的鉛芯橡膠隔震支座與日本生產(chǎn)的鉛芯橡膠隔震支座具有同樣優(yōu)良的性能。

Studies on contrast shaking table tests on models with lead rubber bearing made in China and Japan are conducted. Experimental results between the two isolated models and the fixed model are compared. The performances of the two isolated systems are presented and also compared here. The results prove that the selected isolated systems can reduce the response of structure effectively and the performance of Chinese lead rubber hearing is as good as that of Japanese. The conclusions can provide a reference for engineering application.
Keywords:  lead rubber bearing; model test; isolated system performance
