摘　　要：层间隔震结构是隔震技术的新发展,它将隔震层设置在建筑物某层柱子和楼板之间进行结构的地震反应控制。层间隔震结构在减震机理、振动特性以及设计方法等诸多方面有别于基础隔震结构和屋盖隔震结构。本文对层间隔震结构的适用范围、优点以及其在实际工程中的应用情况进行了综述,最后,指出了层间隔震结构需要进一步研究的问题。现有的研究成果和工程应用情况表明,层间隔震结构具有明确的减震效果,施工方便,是一种具有发展前途的减震体系。The story isolation is a newly proposed isolation system, in which, the flexible laminated rubber bearings are inserted between a floor and the columns that support it. It is different from base isolation system and roof isolation system in many aspects, such as, its vibration reduction mechanism, dynamic characteristics and design method, etc. The purpose of this paper is to summarize the state-of-the- art of the story isolation system about its applicable range, advantages, applications in practical engineering, and some problems to be investigated. It is found that the story isolation system is effective,and easy to be constructed, which has potential to become an attractive way to reduce structural seismic response.
