摘要
通过对一座具有非对称布置的独塔单索面斜拉桥的分析,应用MSC有限元分析软件建立3 D全桥结构有限元模型,对斜拉桥结构进行动力特性计算,将所得计算结果与现场测试结果进行分析比较,通过比较说明3 D有限元模型是合理的、准确的.文中所采用的计算方法对同类型桥梁的计算具有参考意义.
By analysing a single-column pylon of a single-cable-plane-cable-stayed bridge with asymmetry disposal, 3D structural model for entire bridge is built by finite element analysis software NASTRAN and the dynamic characteristic of the cable-stayed bridge is calculated. The contrast between the data from computation and the data from experimentation shows that 3D structural model is reasonable and exact. The computation method used in the paper can provide reference for this type of bridge.
