摘要
以某大跨斜拉桥为例,建立了一个比较完整的斜拉桥动力特性有限元模型,通过计算得到了该桥的动力特性,采用单单元和多单元模型模拟斜拉索,分析了拉索本身振动对斜拉桥的整体动力特性的影响。
Taking some cable-stayed bridge as an example, the paper establishes the complete cable-stayed bridge＇ s dynamic finite element model, concludes the dynamic features of the bridge through calculation, adopts unitary and multi-unit model to simulate the cable, and analyzes the influence of the cable＇s vibration on the general dynamic features of the cable-stayed bridges.
