| Abstract: | T-shaped prestressed concrete beam with low web applied to the small-span bridge is intro- duced here. Taking 20m simply supported beam for example, section efficiency and transverse dia- phragm was analyzed, then transversal distribution factor was calculated by analytic method and finite element method. The analysis approves that, T-shaped beam with low web can be applied to small- span bridge. |
