| Abstract: | The shear lag of the broad flange beam is studied. The phenomenon that top plate is not symmetrically relative to the web is revised by adopting different factors. Then the paper studies the variable section bridge of small curvature by using the average inflexibility method to get the value of shear lag and check it with the three-span variable section bridge. The results show that it can be used and it accords with the model's results. Finally, we analyse results of the shear lag of two-span bridges of different ratios of height and width. |

| Keywords: | broad flange beam variable cross section shear lag |
