摘要： 本文用比拟杆法计算T形梁翼缘的剪力滞效应,并对已往按翼缘有效宽度计算截面抗弯惯矩中存在的一种模糊概念进行了澄清,从而使现行的简化计算方法所得的翼缘应力值与实际的最大应力值得到了符合。

Abstract: In this paper, shear lag effect in cantilever box girder is studied by various approaches assuming spanwise displacement as quartic parabola. Fur thermore the finite difference method is adopted in solving negative shear effect on cantilever box girder with linear varying depth. Theoretical results are also compared with perspex model test. Finally, several preliminary Conclusions are drawn regarding further study and research.
