| 摘 要： | 该文论述了采用空间有限元法分析波形钢腹板组合箱梁的剪力滞效应。在分析中考虑了集中力和均布力两种最典型的荷载工况。分析得到的结果与等代腹板的混凝土箱梁剪力滞效应进行比较,比较结果表明两者剪力滞变化规律相同,只是波形钢腹板组合箱梁的剪力滞系数略大。最后,根据分析结果得出一些有参考价值的结论。

| Abstract: | This paper analyzes the shear lag effect of the composite box girder with corrugated steel web by 3D finite element method. In the analysis, two typical loadings of the concentrated force and uniformly distributed force are considered. The analyzed result is compared with the shear lag effect of concrete box girder with equivalent web. The comparison results show that two kinds of shear lag varying rules are same. Only the shear lag coefficient of composite box girder with corrugated steel web is slightly l... |
