| Abstract: | Some horizontal and vertical cracks appeared in the bottom near the mid-span of main girder for a simply supported T-shaped beam bridge, and a large number of inclined cracks occurred in the web near bridge supports. This paper detected carrying capacity of the T beam bridge by load test and analyzed the disease cause. Then the bridge was strengthened by external prestressing method. |
