摘要
桥梁结构的动力特性(固有频率和振型)是结构动力分析和抗震分析的重要参数.以南宁永和大桥为研究对象,通过建立空间结构模型,计算分析了钢管混凝土拱桥的动力特性,探讨了主要结构参数对其动力性能的影响,为该类桥梁的抗震设计研究提供了分析的基础.
The dynamic behavior （natural frequencies, vibration shapes of a bridge）is the important parameter for the dynamic and seismic analysis of structure. Yonghe Bridge of Narming has been taken as a research project. The space model of structure was built up and the dynamic property of concrete filled steel tube arch bridge was calculated and analyzed. The influence of main structure parameters for the dynamic property was also discussed. A useful exploration on this type of bridge is made for the seismic design.
