摘要
通过对单自由度非线性体系在１４条强震记录作用下的地震反应分析计算，得到了 适用于结构抗震设计的弹塑性延性谱．应用弹塑性延性谱，结构设计人员可以迅速确定结构 抗震设计所必须满足的延性指标，避免结构方案可能的修改，从而使结构抗震设计变得更加 合理．
A ductility spectrum, which was based on the analysis of earthquake response of nonlinear system by fourteen digital records of strong motion, was preseted in this paper. Applying the ductility spectra to earthquake-resistant design, the structural designers can decide the ductility requirements in seimic design quickly, and avoid the amendment for structural schame.
