| 摘 要： | 本文以一座1～80米客运专线钢箱梁—钢管混凝土拱组合结构为例,采用大型有限元软件Midas civil建立其空间计算模型,研究了该桥的动力特性;探讨了三种不同吊杆形式、拱肋不同部位的横撑以及横撑刚度对结构自振特性的影响。通过研究,得到了一些规律性的结论,为同类钢管混凝土拱桥的动力分析和优化设计提供了一定的参考和借鉴。

| Abstract: | Based on an 80-meter steel box girder-concrete filled steel tubular arch bridge in one of the passenger transportation railway lines,a 3D computational model is established in this paper by adopting the large-scale finite element analysis software-Midas\civil,meanwhile the dynamic characteristics and the effect on the natural characteristics of vibration are studied under the condition of three different kinds of layout of suspenders,different position of transverse supports on arch rib and the stiffness of traverse supports.Some regularities are obtained by further research, which could provide some references for the dynamic analysis and optimization desigfi of similar steel box girder-concrete filled tubular arch bridges. |
