摘    要:桥梁结构自振特性分析是进行地震反应分析及风振分析的理论基础,系统而深入的认识桥梁结构的动力特性是十分重要的。通过以润扬南汊悬索桥为研究对象,分析了对其实施环境随机测试的过程及结果,并根据润扬南汊悬索桥的设计图纸用大型商业有限元软件ANSYS建立了悬索桥的三维有限元模型,对成桥后的动力特性进行计算,并与实测值进行了对比分析,结果比较吻合,为该桥进一步动力分析提供了理论基础。

关 键 词:润扬悬索桥  环境激励振动  动力特性  三维有限元模型

Abstract:The dynamic characteristics analysis of Runyang suspension bridge as the basis of earthquake analysis and wind vibration analysis is presented with ambient vibration measuring conducted to obtain the dynamic characteristics of the bridge.The three-(dimensional) finite element model was established for Runyang suspension bridge based on design drawing,and then the dynamic(characteristics) of computation modality were analyzed.The calculated results agreed with the measurement.The analysis provided(theoretical) basis for further study of the suspension bridge.
Keywords:Runyang suspension bridge  ambient vibration  dynamic characteristics  three-dimensional finite element model
