Bridge structure condition evaluation has important practical significance for ensuring safe operationof bridge and increasing transport efficiency. Considering the defects of existing regulations and traditional analytical methods and taking the upper main beam structure of medium - small span bridge as the study object, evaluation index system of bridge durability is established, uncertain analytic hierarchy process is adopted to calculate index weight, so as to reduce the effect of subjective factors and finally realize durability condition evaluation of bridge.
