| Abstract: | The typical diseases for a simply-supported T-beam bridge during long-term operation, such as force cracks at the midspan and the force steel corrosion, seriously affect the structural carrying capacity and durabili- ty. According to the load test results, a targeted strengthening method is adopted for the bridge and the canying capacity can meet the need of the design load of the bridge. The maintenance method can be a reference for the same engineering. |
