摘  要：基于性能的抗震設計方法是國際先進技術，適用于復雜超限高層建筑的結(jié)構(gòu)設計。我國規(guī)范采用“小震不壞、中震可修、大震不倒”的抗震設防目標，超限高層結(jié)構(gòu)可通過抗震設計來實現(xiàn)我國規(guī)范要求的性能目標。該文以重慶某復雜超限高層項目為例，介紹該結(jié)構(gòu)性能化設計的過程。

關鍵詞：性能設計；超限高層；彈塑性；時程分析；SAUSAGE

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.

Keywords： performance design; out-of-gauge high-rise building; elastoplastic; time-history analysis; SAUSAGE
