| 摘 要： | 研究了一种以位移为基础的抗震设计方法，用等效线性化方法，在弹性位移设计谱的基础上形成用于以位移为基础的抗震设计非线性位移设计谱，将结构延性作为设计目标，提出一种以结构原始弹性刚度作为等效刚度的以位移为基础的抗震设计方法，以桥梁墩柱为例，给出了一个完整设计过程，并将其设计结果与文献「１」进行了比较。

| Abstract: | A displacement based seismic design method was discussed.Using equivalent linear method, a kind of nonlinear displacement design spectrum used in displacement based seismic design was derived from the elastic displacement design spectra. And with the design targeted at the ductility of the structure, a new method was established in which the elastic stiffness of the structure was used as the effective stiffness based upon the nonlinear displacement design spectra. A comprehensive procedure for displacement based seismic design of cantilever bridge columns is presented and is verified with reference1] |
