摘　　要：直接基于位移的抗震设计是实现基于性能抗震设计思想的一条有效途径,其理论主要包括三方面的内容,即直接基于位移的抗震设计方法、位移需求估计方法和目标位移的确定。本文在阅读了大量文献的基础上,对国内外在这三方面的研究进行了介绍,并对今后的研究方向进行了展望。The direct displacement-based seismic design is an effective way to fulfill the principle of performance-based seismic design. It mainly consists of the following three aspects： procedures of direct displacement-basedseismic design, methods of displacement demand estimation and the determination of target displacement. In this paper, these three aspects are reviewed based on the research achievements home and abroad, and the prospect of the future trends is also presented.

关 键 词：基于性能的抗震设计 直接基于位移的抗震设计 位移需求估计 目标位移
