摘要
本文应用桁段有限元素法,将每个桁段节间作为一个单元,每个桁梁节间断面有10个自由度,分析了中国某特大钢桁梁桥的自振特性。文中详细研究了横联设置对钢桁梁桥动力特性的影响,所得结果可供新结构设计参考。
Using the finite truss-element method and taking each truss length as an element where there are ten degrees of freedom in each node cross section of truss element we have analysed the vibration characteristics of a certain larger steel truss bridge in China.In this article a detailed study is made on the effect of installing cross join system upon the dynamic characteristics of steel bridge The result obtained can beused used for reference in designing new structure
