摘  要：基于性能的抗震设计方法是国际先进技术，适用于复杂超限高层建筑的结构设计。我国规范采用“小震不坏、中震可修、大震不倒”的抗震设防目标，超限高层结构可通过抗震设计来实现我国规范要求的性能目标。该文以重庆某复杂超限高层项目为例，介绍该结构性能化设计的过程。

Abstract： The performance-based seismic design method is an internationally advanced technology， which is applicable to the structural design of complex and out-of-gauge high-rise buildings. The code of China adopts the basic objective of seismic fortification of "unbreakable by small earthquake， repairable by moderate earthquake and not collapsed by large earthquake". The performance objective required by the code of China can be achieved through seismic design of out of gauge high-rise structures. Taking a complex super high-rise project in Chongqing as an example， this paper introduces the process of performance-based design of the structure.
