【摘要】 对一圆盘形钢箱人行天桥进行深入细致地有限元计算分析 ,与现场测试结果进行比较后发现 :有限元计算结果与实测值有很好的一致性 ;对人行天桥的安全性能作出了评价 ;讨论了纵肋、横隔板以及桥面混凝土铺装层对结构的贡献更多还原

【Abstract】 Finite element method(FEM) is applied to analyze a disc shape pedestrian platform bridge with steel box section.After analyzing lots of the calculating results,the FEM’s calculating results are compared to those measured with good agreement,and the safety of the pedestrian platform bridge is judged.Finally,contributions of longitudinal ribs,lateral partition boards and concrete pavement to the structure are discussed.更多还原
