摘要：The determination of traffic-load effects, which guarantee the safety evaluation results credibility, is an important step for safety evaluation of arch bridge suspenders. Focusing on the traffic-load effects calculation for arch bridge suspenders, firstly, the special feature of traffic-load effects, "sit-specific" "component-specific', was talked about, and the importance of traffic-load effects measured value was pointed out too; secondly, the component of suspenders' load effect monitoring system with fiber sensor was introduced in detail; finally, the theory and process of the maximum value of suspender's traffic-load effects during the rest service period using in-service data was researched. Using this maximum value in safety evaluation, the evaluation result is closer to the real situation.
