| 摘 要： | 由于剪切变形和畸变的存在，求解腹板高度不同的薄壁箱梁各截面应力时，使用梁单元无法精确求解，如果全桥都采用实体单元，则求解规模偏大。而使用子模型法对单箱单室左右腹板高度不同的薄壁箱梁进行分析，可解决实际问题。

| Abstract: | Due to shear strain and aberration, we can not accurately obtain the solution by using beam elements when we solve section stress of thin-walled box girder of different height webplate web height of thinwalled box.Solving scale is relatively large if we use entity cell in the whole bridge. Some problem could be solved if we use the sub-model technology to analyze simple-box simple-cell and webplate with different height thinwalled box girder. |
