| Abstract: | Focusing on the problem of suspender's monitoring and safety evaluation, a suspenders' load effect monitoring system with fiber sensor was set up on the Ebian Dadu River Bridge in Sichuan province. The component of this system was introduced in detail. The theory and process of traffic load effect analysis using in-service data was researched. The safety evaluation criterion for suspender was set up. Finally, the system carried out a test run. The test result shows that the system can effectively monitor the traffic load effect, so that the evaluation result is closer to the real situation. |
