摘要
通过对国内某高低塔单索面斜拉桥建立三维空间有限元模型,进行了自振频率、振型的模态分析,总结了该结构体系斜拉桥的动力特性,可为同类桥梁的分析提供参考。
In this paper,a three-dimensional finite element model for a higher-lower tower of single-plane-cable-stayed bridge is created to analyze it s natural frequency and modes.Sum up the dynamic characteristics of such cable-stayed bridge and can serve as reference to the analysis of similar bridges.
