脊骨梁扭转效应的分析与实验研究

Analysis of the torsion effect and experiment research on the spine box girder

以脊骨梁模型实验为基础,应用有限元软件ANSYS建立三跨连续脊骨梁空间模型,分析了扭转对脊骨梁应力的附加影响,并对脊骨梁进行了参数分析,进一步研究总结脊骨梁桥的扭转特性,用来指导设计。

According to the spine box girder model experimental, using finite element software ANSYS in the establishment of three-span continuous spine box girder space model, analysis the spine box girder＇ s additional stress of torsion. Analysis the mechanical parameters of the spine box girder, research and summarize some of the torsion properties furthermore, the results are used to guide design.
