摘要: 以玉溪大桥为研究对象,通过有限元分析软件ANSYS构建拱桥的模型,然后进行模态分析,研究拱侨的动力特 性.最后进行时程分析,施加Taft地震波来计算拱桥在拱顶、1/4以及拱脚截面处的应力、位移和最大弯矩并且采用 TMD进行减震设防.

关键词: 动力特性, 模态, 时程分析

Abstract: The model for Yuxi bridge was constructed on the basis of ANSYS.The research for the dynamic characteristics was made by mode analysis.Taking the arch crown and quarter section of the arch ring as key sections,by exerting Taft seis- mic wave on the bridge,the stress,displacement and the maximal moment of key sections were computated by the time-history analysis and the TMD equipment was used to reduce the seismic intensity.

Key words: dynamic clmracteristics, mode, time-history response analysis
