| 摘 要： | 文章结合具体工程实例,介绍了单箱多室斜交箱梁的剪力滞分析思路,并通过建立三维实体有限元模型,对比分析了正交桥与斜交桥剪力滞效应的差异,探讨了宽高比、斜交角等结构参数对单箱多室斜交桥剪力滞效应的影响。研究发现,单箱多室斜交箱梁桥的剪力滞效应与正交桥相比有很大差异,同时其参数敏感性也更加显著。

| Abstract: | Combined with the construction practice,the article introduces the shear lag effect of single box multi over skew girder.By building a 3D finite element model,the article per-forms comparison analysis on the difference of shear lag effect on right bridge and skew bridge.It also discusses the width and height ratio,skew angle and other structure index on the influence of shear lag effect.The study result shows that there is a huge difference between the effects on right and skew bridge,and the sensitivity of... |
