Fuzzy Comprehensive Evaluation of Durability of Existing Reinforced Concrete Arch Bridges
-
摘要: 考虑到钢筋混凝土结构耐久性影响因素的复杂性,运用模糊数学,对既有钢筋混凝土拱桥耐久性的合理评估进行了探讨.将钢筋混凝土拱桥分为构件和结构2个层次,并建立相应的隶属函数,从而得到既有钢筋混凝土拱桥耐久性的评估模型;利用所建立的模型,对某钢筋混凝土拱桥的耐久性进行了评估.结果表明,模糊综合评估具有较好的工程实用性.Abstract: To reasonably evaluate the durability of existing reinforced concrete arch bridges the fuzzy mathematics was applied due to its complicated influencing factors. With this method,a reinforced concrete arch bridge is divided into the two layer levels of members and structures,and the corresponding membership functions are established to obtain the evaluation model for the durability of existing reinforced concrete arch bridges.This model has been used to evaluate the durability of an existing reinforced concrete arch bridge,and the evaluation result demonstrates the validity of this method.
