摘要
以某轨道交通工程高架地铁车站为背景,建立有限元计算模型,分析地震作用下高架车站墩柱结构的地震反应。结果表明:在多遇地震作用下,该高架车站墩柱强度满足规范要求;在罕遇地震作用下,该高架车站墩柱非线性位移延性比满足规范要求。计算结果已为该高架车站的抗震设计提供依据,分析方法可为同类结构提供参考。
Based on an elevated metro station, the finite element model is established to research the seismic response of the station under earthquake. Research results show that the strength of the pier column meets the requirements of the specifications in case frequent earthquake, while the value of the nonlinear displacement ductility ratio of the pier column satisfies the standard in case of rare earthquake. The results are taken as the theoretic basis for the project and the analytical method may serve as reference for similar structures.
