［摘要］我国《建筑抗震设计规范》(GB 50011—2010)和《高层建筑混凝土结构技术规程》（JGJ 3—2010)均首次正式引入了性能化抗震设计的方法，对地震动水准、性能目标、性能水准组合及计算方法等性能化抗震设计的关键内容做出了明确规定。美国太平洋地震工程研究中心也于2010年发布了《高层建筑基于性能设计方法指南》（PEER-2010)，首次将性能化抗震设计方法正式引入到新建高层结构的抗震设计中。对比我国规范以及PEER-2010中建议的性能化抗震设计方法的主要异同，阐述中美两国性能化抗震设计方法的特色，并按照我国规范规定的性能化抗震设计方法，对某超限高层建筑进行了性能化抗震设计。探讨了我国规范引入的性能化抗震设计方法的合理性与实用性，并对其进一步的发展提出了建议。

Abstract: The performance-based seismic design method was firstly introduced in the Chinese  codes of Code for seismic design of buildings (GB 50011—2010) and Technical specification for concrete structures of tall building (JGJ 3—2010). Key contents in performance-based seismic design were clearly specified in the codes including ground motions, performance objectives, performance level combinations and calculation methods. The American Pacific Earthquake Engineering Research Center also published Guidelines for performance-based seismic design of tall buildings（PEER-2010) in 2010 to introduce the performance-based seismic design method into designs of newly built high-rise buildings. Main differences and similarities of the performance-based seismic design methods of the Chinese codes and PEER-2010 were compared and the main characteristics of performance-based seismic design methods in China and USA were demonstrated. Based on the performance-based seismic design method of the Chinese codes, the performance-based seismic design was carried out for an out-of-code high-rise building. The rationality and applicability of the codified performance-based seismic design method were discussed and suggestions were made for the further development of the performance-based seismic design method.

Keywords:code; out-of-code high-rise building; performance-based seismic design
