摘要
根据混凝土结构耐久性评估指标多层次、多因素和模糊的特点,本文建立模糊可拓层次分析法对混凝土结构耐久性进行评估。该方法通过可拓区间判断矩阵,计算各层次评价指标权重,结合模糊综合评价方法进行逐级评价,最终得出综合评价值。本文结合马鞍山钢铁公司第三轧钢厂办公楼进行混凝土结构耐久性评估计算,结果表明:模糊可拓层次分析法较传统层次分析法更为科学、全面、准确、便捷,可以用于对在役混凝土结构进行耐久性能评估。
In the paper, Fuzzy extension AHP（Analytic Hierarchy Process） model is proposed to evaluate concrete structure durability, according to the concrete durability indexes are multi- pie-levels, multiple-factors and fuzzy. In the method, the extension interval judgment matrix is applied to calculated the weight of every durability index, at the same time the fuzzy compre- hensive evaluation method is used which can obtain every evaluate grade level by level, there- fore the ultimate evaluation result is obtained. The fuzzy extension AHP method is applied in the office building of the third rolling mill of Ma＇anshan steel company. The analysis result shows that the fuzzy extension AHP method is more scientific, comprehensive, accurate and convenient than the traditional AHP method, which can evaluate the durability of concrete structure effectively.
