钢筋混凝土结构耐久性评估的研究

Durability of reinforced concrete structure of the assessment

总结目前既有钢筋混凝土耐久性评估的方法,将评估等级分为5个等级,给出服从梯形或半梯形分布的隶属函数,来确定构件耐久性影响因素对各个等级的隶属度,运用层次分析法确定初始权重后,将提出根据影响因素实际检测结果进行权重修正的更加合理确定权重的方法,对模糊综合评估结果进行分析处理,建立既有钢筋混凝土结构耐久性的模糊综合评估模型,应用于工程实际,可用于多种类型的钢筋混凝土耐久性评估,具有普遍性。

To summarize the current assessment of existing reinforced concrete durability method to assess the class is divided into five levels,given the distribution subject to trapezoidal or semi-trapezoidal membership functions to determine the factors of durability of components of each level of membership,the use of AHP to determine the initial weights,will be made according to impact factors,the actual weight of the test results for a more rational correction method to determine the weight,fuzzy comprehensive evaluation of treatment results were analyzed to establish both the durability of reinforced concrete on the Fuzzy evaluation model,used in the actual process of soil can be used for various types of reinforced concrete durability assessment,universal.
