Abstract: The analytic hierarchy process and the fuzzy systems theory to set the fuzzy comprehensive evaluation of durability of concrete bridge were combined. And through the example of a project, the evaluation process of durability after strengthening were given., and it's practice in engineering is proved.
Keywords: durability; fire; strengthen; fuzzy comprehensive evaluation
