| 摘 要： | 根据钢筋混凝土构件耐久性评估的特点，借助模糊数学的理论，将结构构件的损伤程度作为构件这一论域U上的模糊子集A，利用所构造的多元隶属函数，对构件的损伤程度进行评价，提出了一种耐久性分极评定方法，这一方法克服了以往在结构构件评价中存在的主观、经验等因素，该法的特点是使耐久性的每一级别都有确切的剩余寿命的内涵，而多元隶属函数法的引入减小了主观因素对评定结果的影响。经实例验算，该法准确率可达90%。

| Abstract: | Based on the property of durability assessment for RC members and with the help of fuzzy mathematical theory,a method for grading assessment of durability is presented in this paper The feature of this method is that each durability grade relates with the corresponding residual service life The use of multivariate membership grade function diminishes the influence of subjective factors for different person The grading cases indicate that the accuracy rate of this method can reach to about 90% |
