摘要：An overview of earthquake resistant building with base isolation technology is given in this paper which elaborates the construction, working principle and design structure o f base isolation system. Base Isolatio n is a state-of-the- art design strategy that substantially decouples (isolates) a building from the damaging effects of earthquake ground mo tion. It can be used to dramatically reduce earthquake forces by factors of 5 to 10 on mid-rise buildings (2 -15 stories tall), and make a Magnitude 8.0 earthquake seem like a much less damaging Magnitude 5.5 event. Base isolation, also known as seismic or base isolation system, is a collection of structural elements which should substantially decouple a superstructure from its substructure resting on a shaking ground thus protecting a building or no n-building structure's integrity .Base isolation is the most powerful tool of the earthquake engineering pertaining to the passive structural vibration control technologies. It is meant to enable a building or non-building structure to survive a potentially devastating seismic impact through a proper initial design or subsequent modifications. In some cases, application of base isolation can raise both a structure's seismic performance and its seismic sustainability considerably. Contrary to popular belief base isolation does not make a building earthquake roof as there is no such thing.
