用U变换法分析薄壁箱形连续梁的组合扭转

Analysis of Combination Twisting of Thin-Walled Box Girders with Periodic Supports by the U-Transformation

用U变换法分析具有周期性支承的薄壁箱形连续梁的组合扭转。连续梁的控制方程经U变换解耦后,建立了子结构规模的控制方程和边界条件;并结合具体载荷条件,给出了位移和内力相应的解析表达式。

The combination twisting of thin-walled box girder with periodic supports bas been analyzed by the U-transform method. The uncoupled governing equations with boundary conditions for single substructure can be derived using the U-transformation. Some specific loading conditions are considered. The angular displacements and bimoments have been derived.
