| Abstract: | In this paper , the calculation formula and boundary conditions of shear lag effect of the cantilever box girder with varying depth are deduced by the energy-differential method and the difference method. An example of a real bridge modal test is given to prove the accuracy and reliability of this method and the disciplinarian of root section with subsection distribution load is analyzed. Lastly the paper gives rational suggestion for this structure's construction. |
