| 摘 要： | 采用"板壳元法"对某扁平薄壁钢箱梁人行天桥进行有限元分析,并将计算结果与"梁格法"分析计算结果比较。结果表明:两种有限元模型分析结果拟合较好。相比较,"板壳元法"有更好的模型深度,当结构体系简单时,宜优先采用"板壳元法"。

| Abstract: | Adopting plat and shell element method of the finite element method analysis pedestrian overpass of continuous flatspot thin-walled steel box girder,in order to compare with the analysis result of grillage method.The results indicate that two kinds of finite element model fitting is good.Because plat and shell element method has a deeper anslysis,while structure feature is not complex,it is recommended to selecte plat and shell element method preferentially. |
