摘　　要：在近30年里,日本已经建造了超过2500座隔震建筑。最初,由于很难将隔震系统应用于高层建筑,故其主要应用于中低层建筑中。然而,现阶段隔震装置的性能得到了提高(特别是叠层橡胶支座),因此近年来隔震系统开始应用于高层建筑。随着隔震系统适用范围的扩大,一些以前没有考虑过的与隔震系统相关的新挑战和新问题相继出现。然而,不断应对新挑战必须依赖隔震技术的进步。本文回顾了2011年东日本大地震前后隔震技术的情况。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.
