摘要
基于国内在建的大跨度叠合梁斜拉桥,采用ANSYS软件分别建立了全桥结构的梁-壳单元三维有限元模型与单主梁三维分析模型,对该叠合梁斜拉桥的动力特性进行了分析,并通过比较考察了不同计算模型之间的偏差。
Based on a under-construction cable-stayed bridge with long span and composite beam in China,the three-dimensional finite element model of bridge structure based on beam-shell element and single girder three-dimensional model are established by ANSYS software respectively.The dynamic characteristics of the composite-beam cable-stayed bridge are analyzed,and the difference between the two models is compared and observed.
