| 摘 要： | 本文基于某5跨连续中承式钢管混凝土拱桥,借助有限元软件MIDAS,建立了该桥的空间有限元分析模型.对其振型特征进行了分析,求出了自振频率、振型等动力参数.并通过变换拱桥的主要结构参数分析了它们对自振特性的影响.计算结果为连续中承式钢管混凝土拱桥的抗震设计提供了参考.

| Abstract: | This paper is based on a 5-span continuous half-through CFST(concrete filled steel tube) arch bridge.Spatial finite element analysis model is established by the software-MIDAS to analyze the characteristics of this mode and calculate dynamic parameters such as self-vibration frequencies and modes.Meanwhile the influence of self-vibration characteristic is analyzed when primary structural parameters are changed.The computational results of the paper may be applied to seismic design of the continuous half-thr... |
