| 摘 要： | 为了对钢管混凝土拱桥进行结构优化,利用有限元通用软件ANSYS,对一座下承式钢管混凝土拱桥进行了自振特性分析。文章通过变换拱桥的矢跨比和横撑形式,来讨论了它们对结构自振特性的影响。分析发现该拱桥的振动主要有拱肋的面外横向振动、桥跨结构整体竖向振动和桥跨结构扭转振动;矢跨比对拱桥结构自振频率影响比较小;＂K＂形、＂米＂字...

| Abstract: | In order to optimize the concrete-filled steel tube arch bridge,the general finite element software ANSYS is used to analyze the self-vibration characteristics of a under-supported concrete-filled steel tube arch bridge.Through transforming the rise-span ratios of the arch bridge and forms of horizontal support,their influence on self-vibration characteristics is discussed in detail.It is found from analyses that the vibrations of the arch are main the transverse vibration outside the plane of ribs,the vert... |
