| 摘 要： | 本文将目前美国《预制节段箱形梁手册》所推荐的箱梁横向内力分析的“ＴＹＬ”框架分析法推广到带伸臂的单对称梯形箱,使单对称矩形箱及双对称矩形箱都成为它的特例,因此在工程实践中运用范围更加广泛。本文还通过算例比较,说明截面梯度对横向内力的影响。

| Abstract: | The application of TYL frame method recommended by the "Precast Segmental Box Girder Bridge Manual", is extended here in this paper to the box girder of trapezoid section with cantilevers. For the structural analysis the calculating formulas of the method proposed are derived The applicability of the method is in a wider range of engineering practice than the former. Ex- ample of comparison is presented to show how the slope of the web influences the transverse internal force, and some conclusions are drawn from the compariscn. |
