摘要
简述了部分斜拉桥兼有梁桥和一般斜拉桥的结构特点,并以联台大桥为例,基于ANSYS平台建立了联台部分斜拉桥的有限元计算模型,并对其进行模态分析,得出该桥箱梁结构设计合理,有限元计算模型正确,边界模拟条件符合工程实际的结论。
This paper briefly describes structure features of some cable-stayed bridge together with girder bridge and common cable-stayed bridge.With Liantai Bridge as an example,it establishes finite element calculation model of some Liantai cable-stayed bridges on the basis of ANSYS platform,makes a simulation analysis for it.Results show that： the bridge box girder design is reasonable,finite element model is correct,and the boundary simulation conditions meet the engineering conclusions.
