摘要
通过大型结构有限元分析软件ansys12.1对一个120m的系杆拱桥建立了动力分析模型,并进行了模态分析。并且在此基础上采用了动力反应谱分析方法计算了结构的地震响应,并且得出了各节点的位移时间历程关系,所得到的结论可以为中大跨度的系杆拱桥的设计以及抗震分析提供相关的根据。
Through large structure finite element analysis software ansysl2.1, arch bridge of a 120 m dynamic analysis model is established, and a modal analysis is carried out. And based on this ground- work, the dynamic response spectrum analysis method is adopted to calculate the seismic response of the structure, and the relationship between the displacement time history of each node is obtained, the con- clusions can provide related evidence arch bridge of large span aesign and for seismic analysis.
