摘要：The service durability of bridge slings is directly related to the safety of the entire bridge and has become one of the important indicators for measuring the performance of bridge structures. How to make a more accurate assessment of bridge slings is a problem that bridge management and maintenance departments must consider. Based on the investigation of the durability damage of the bridge sling structure in China, this paper establishes a comprehensive evaluation system for the durability of the bridge sling structure, divides the evaluation criteria, and proposes the durability of the sling based on set pair analysis Sex evaluation methods. On the basis of calculating the weight of the durability evaluation index by the analytic hierarchy process, the durability level of the bridge sling structure is accurately quantified through the set pair analysis operation. The example application shows that the method proposed in this paper has a good engineering application prospect.
