近几年来,直接以位移为设计参数的抗震设计方法越来越受到重视并且得到了很大的发展,逐渐成为了实现基于性能抗震设计思想的一条有效途径。本文介绍了基于性能的结构抗震设计方法,阐述了基于位移的抗震设计的理论与方法,并对直接基于位移的抗震设计方法、控制延性的抗震设计方法和能力谱方法进行分析和比较。 In recent years, the seismic design method which directly takes the displacement as the design parameter has drawn more and more attention and has been greatly developed, and has gradually become an effective way to realize the performance-based seismic design. This paper introduces the performance-based seismic design method of structure, expounds the theory and method of displacement-based seismic design, and analyzes and compares the direct displacement-based seismic design method, the aseismic design method and the ability spectrum method to control ductility.
