| Abstract: | Based on FEM,a detailed analysis on the shear lag effect of long-span concrete box girder bridge under thermal action is conducted in this paper. It is found that the shear lag effect of the bottom surface of the flange slabs under thermal action is obviously. And some conclusions are obtained which provide design consults for box girder determined under thermal action. |
