摘要
利用有限元法分析大跨度钢管混凝土拱桥的地震反应,考虑了剪切变形的影响,用子空间迭代法分析了其振动规律和动力特性,应用反应谱法和时程分析法分析了该拱桥的地震反应,得出了一些有价值的结论。
In this paper, dynamic response was investigated using the finite element method on a long span concrete filled steel tube (CFST) arch bridge with consideration of the effect of shear deformation. In the investigation, the subspace iteration method was employed for analyzing the dynamic characteristics of the bridge. The seismic response of the bridge was then obtained by means of the spectrum method and time history method, leading to a number of valuable conclusions.
