| 摘 要： | 采用变分法和有限元法分析在自重作用下简支箱形梁的剪力滞效应，同时采用三维实体单元分析，得到剪力滞效应在上下翼板厚度方向的分布规律。通过理论解与数值解的对比可知，采用有限元软件和变分法分析箱形梁剪力滞效应都是可行的。分析得到的规律既可作为箱形梁剪力滞理论分析的验证，也可作为相似箱形梁设计的参考。

| Abstract: | The shear slag effect of simply supported box girders under the deadweight is analyzed by means of variational method and finite element method,and the distribution rule of the shear slag effect in the thickness direction of upper and lower wing plates is obtained via three-dimensional entity unit analysis.The comparison between theoretical solution and numerical solution shows that both finite element software and variational method are feasible for analyzing the shear slag of box girders.The rule acquired from analysis can be used for verification of theoretical analysis on the shear slag of box girders and reference for design of similar box girders as well. |
