Abstract
A finite difference solution is presented for shear lag effect on the box girder with varying depth. The analysis is carried out according to Reissner's method in which the spanwise displacement is assumed to be a quartic parabolic curve on the cross section instead of a quadratic. Under four types of loading, shear lag effects are computed on a cantilever box girder with linearly varying depth. The results are compared with model tests. Finally, some conclusions are drawn about the distribution of shear lag effect along the cantilever box girder with varying depth.
