摘　　要：参考国内外研究成果和现行规范,系统阐述了影响钢筋混凝土结构耐久性的十大因素,在划分其影响级别后,采用模糊数学和层次分析法理论,建立了钢筋混凝土结构耐久性AHP-FUZZY评定模型。对某暴露于北方自然环境下的单层框架结构进行了算例分析,验证了该方法的有效性。本方法所得耐久性评定结果可作为结构鉴定、加固或拆除的决策参考。Based on research findings in the past and accepted standards at the present,multi-influencing factors which affect the durability of reinforced concrete structure are analyzed.After carrying on the divisions of its influence grades, the AHP-FUZZY assessment model for the dura- bility of reinforced concrete is established applying the fuzzy n^athematics theory and the analytic hierarchy process.Using this model, the durabili- ty assessment for a built reinforced concrete structure exposed in the northern of China is evaluated.The fuzzy synthesis evaluation method is effec- tive to inspect a built reinforced concrete structure.
