| 摘 要： | 结合具体工程对小曲率钢箱梁桥进行计算研究,对比分析在不同截面形式下的受力特性,并对曲线钢箱梁桥的受力特点、剪力滞效应和最优截面方案进行综述和研究。分析表明:对于大跨度薄腹钢箱梁桥,增设横隔板和必要的纵肋是减小截面畸变变形的最优方案。

| Abstract: | Curved steel box girder bridge of small radius has been studied by a specific project in this essay. Using the method of finite element, the essay has compared the mechanical properties of curved steel box girder bridge with different section types and analyzed the shear lag effect and the best choice of section of steel box girder bridge. The re- sults show that for long-span steel box girder bridge with slender web, using cross spacer and necessary longitudinal rib is the most efficient way to reduce distortion of the section. |
