摘　　要：基于结构性能的抗震设计理论是21世纪国际结构抗震设计发展的主流。本文阐述了基于性能抗震设计理论产生的背景和基本内容,介绍了能力谱、基于损伤性能和能量法等几种基于性能抗震设计的实用方法,以能力谱法为例,设计一个单自由度排架结构以介绍基于性能的抗震设计过程。最后,进行了简单的综述。The theory of performance-based seismic design is the mainstream in the world in 21st century. The background of its occurrence and the basic idea are summarized in this paper, and introduced seismic design on capacity spectrum, damage and energy performance. In order to introduce the process of performance-based seismic design, a single-degree of freedom bent structure was designed with the method capacity spectrum. Simple overview is showed in the end.
