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.
