摘　　要：随着隔震技术的发展,将该技术应用于高层建筑得到了广泛的关注;其中高层基础隔震结构基于性态抗震设防标准的研究还不十分充分。参考国内外相关通则及规范,以及国内学者对于基础隔震结构基于性态的设计方法的研究,依据基于性态的抗震设计理论,结合高层结构的特点,提出了适合高层基础隔震结构的设防标准。主要从三个方面进行研究,包括高层基础隔震结构的功能分类、性态目标及抗震设计类别;将高层基础隔震结构的性态分为五个水准:充分运行、运行、基本运行、生命安全、接近倒塌;最后将高层基础隔震结构的设防目标进行量化,为高层隔震结构的抗震设计提供了参考。With the development of the base-isolated structure, high-rise base-isolated structure has been widely concerned. Research about performance-based seismic design of high-rise base-isolated structure is not enough. Some relevant rules or regulations home and abroad and research about performance-based seismic design of baseisolated structure are referenced, considering the characteristic of high-rise structure, on the basis of performance- based seismic design theory, come up with the rational seismic design criteria of high-rise base-isolated structure. The main content is compose of three components, namely functional category of high-rise base-isolated structure, the performance objective and classification of seismic design for high-rise base-isolated structure. The performance of high-rise base-isolated structure is classified as three levels ： fully run, run, basic run, safety of life and close to collapse. Finally, the fortification objects of high-rise base-isolated structure are quantified as well, and some meaningful references are provided for seismic design of high-rise base-isolated structure.
