［摘要］在近30年里，日本已經(jīng)建造了超過2500座隔震建筑。最初，由于很難將隔震系統(tǒng)應(yīng)用于高層建筑，故其主要應(yīng)用于中低層建筑中。然而，現(xiàn)階段隔震裝置的性能得到了提高（特別是疊層橡膠支座），因此近年來(lái)隔震系統(tǒng)開始應(yīng)用于高層建筑。隨著隔震系統(tǒng)適用范圍的擴(kuò)大，一些以前沒有考慮過的與隔震系統(tǒng)相關(guān)的新挑戰(zhàn)和新問題相繼出現(xiàn)。然而，不斷應(yīng)對(duì)新挑戰(zhàn)必須依賴隔震技術(shù)的進(jìn)步。本文回顧了2011年?yáng)|日本大地震前后隔震技術(shù)的情況。

Abstract:In the nearly 30 years, more than 2500 seismically isolated buildings have been constructed in Japan. Initially it was said that the application of the seismic isolation system  high-rise buildings may be difficult, therefore it was mainly installed in medium and low-rise buildings. However the performance of seismic isolation devices is improved, especially laminated rubber bearings, and recently the seismic isolation system is implemented for high-rise buildings. As an applicable range of seismic isolation system is expanded,  new challenges and new problems  associated with isolation system that have not been considered before appear. While,  repetitions of the responses to new challenges must make technologies progress. The situations of the seismically isolated technology before and after 2011 Tohoku Earthquake were reviewed.Keywords:isolated building； laminated rubber bearing； long-period ground motion； seismic isolation technongy
