摘要
以吉林市临江门大桥为工程背景,进行了现场的脉动试验,采用大型有限元分析软件ANSYS,建立了该桥的三维空间有限元模型,并对其进行了动力特性分析,数值计算结果与动态试验结果比较吻合,说明了该有限元模型能够分析出该桥的动力特性,可为同类型的独塔双索面斜拉桥的动力特性分析提供参考。
In this paper,a three-dimensional finite element model for single pylon and double cable plane cable-stayed bridge is created to analyze the dynamic performance of Linjiangmen Cable-Stayed Bridge in Jilin.The numerical calculation results with the model are agreed fairly well with those of dynamic tests,which manifest that the model can be well used for analysis of the dynamic behavior of the single pylon and double cable plane cable-stayed bridge and can serve as reference to the analysis of dynamic behavi...
