钢管混凝土拱桥空间自振特性的分析

Analysis of the Space Natural Vibration Property for Arch Bridge Made of Steel Pipe Filled with Concrete

建立了钢管混凝土拱桥的空间振动模型，采用多种模式对其空间自振特性进行了计算，绘出了振型图，并同前载试验结果进行了对比，为进一步研究这类结构的动力响应提供参考。

This paper constructs the space vibration models for arch bridge made of steel pipe filled with concrete. The space natural vibration properties are calculated based on several models, and the vibration model graphs are drawn out. At the same time, the calculated results are compared with the dynamic testing results, so that the referece can be put forward for making further study of this kind of structures in the future.
