Abstract

It is set up a fuzzy overall assessment method of concrete bridge durability applying fuzzy theory;based on the multiplayer analysis,this method builds functions that describe the subjection degree of all factors to all grades of durability.Then this method takes the weight of all factors into account and applies the most subjection criterion to get the grade of durability of a concrete bridge,and with this prediction the useful life of durability of the concrete bridge before and after strengthening also can make a quantitatively,so the method is practical.
