摘要
结合龙潭河大桥的工程实例,利用有限元程序ANSYS,分别选用梁单元和壳单元建立有限元模型,对施工和成桥阶段进行线性稳定分析。结论表明:采用梁单元模型对薄壁高墩刚构桥进行稳定分析能得到满意的效果,两种单元模型对比分析得出了一些对该桥初步设计具有参考意义的结论。
This paper takes the Longtan River Bridge as an example, chooses two kinds of elements: beam element and shell element, and establishes the finite element model.The linear stability analysis is carried out with the beam and the shell element respectively by the FEM program ANSYS. Conclusions show that the beam element model can also receive satisfying results on practical projects.The comparative analysis of two models provides a few meaningful references for designing the bridge.
