【摘要】 在分析曲线箱梁力学性能时考虑了剪力滞效应，并且还考虑了曲车半径对箱梁截面特性的影响，推导了曲线箱梁在不同支承条件及载荷型式下的纵向剪切位移差公式。分析结果与文献［５，６］比较表明：本文方法简单而有效。更多还原

【Abstract】 In the mechanical analysis of curved box beam, the shear - lag effect and the effect of curvature anus on the geometric properties of cross - section are considered. And the formulas of longitudinal shear deformation under different support conditions and loading cases are also derived. Finally, the results obtained from this paper compared with these from other references show that the method presented by the author is simple and effective.更多还原
