| 中文摘要 | 针对单索系曲线斜拉桥的结构形式,详细阐述了成都市十陵市政公园8号景观步行桥桥面的方案比选和整体结构布置。通过Midas/Civil结构分析软件建立了该桥的有线元模型,分析了该桥的静力特性并利用子空间迭代法对该桥进行模态分析,得到了该桥的自振频率和和对应的振型,模态分析显示该桥的动力特性满足人行桥的要求。通过此桥,深入的分析了非线性结构计算中位移的计算和控制中使用的一些方法并总结了单索系对桥面刚度和倾覆作用的影响。; The type alternatives of bridge deck system and layout of the structural system of the No.8 pedestrian bridge,which are going to be built in Shiling municipal park,were detailedly explained basing on the structure form of unilateral cable system.The space FEM model was established by using structure analysis software Midas/Civil.Modal analysis result indicates that dynamic character of this bridge accords with the requirement of pedestrian bridge.Some methods for calculating and controlling bridge's displacement in non-linear structures were analyzed and the influence of unilateral cable system to rigidity and anti-overturn capacity of bridge deck were summarized. |
