| Abstract: | This paper analyzes some factors affecting the durability of existing RC beam bridge and creates a two-level bridge durability evaluation model including goal level,item level and index level according to the structure components and mechanical property of the existing beam bridge.Rating criterion of indexes are quantified by taking expert experience and research result of existing documentations into account,and the weight vectors of item layer and index layer are calculated by AHP.An example of evaluation for the durability of a simple supported RC beam bridge is given in the paper. |
