摘要
应用大型通用有限元软件ANSYS对某大跨度独斜塔斜拉桥的动力特性进行了计算分析,讨论了空间有限元模型的建立,分析了构件参数对动力特性的影响,得出了可供该类型桥梁设计应用的结果,并为该类型桥梁的进一步抗震分析提供了相关数据。
In this paper, A 3-D finite element model of the whole single slanted pylon cable-stayed bridge was established by the CAE software ANSYS, and its dynamic characteristics were calculated. Then, on the basis of this result, the paper summarized the dynamic characteristic of these special bridges. The information can be used for the design and anti-seismic analysis of the cable-stayed bridges.
