摘　　要：由于周围环境、使用年限等对建筑结构的影响,一些既有建筑结构在安全、适用和耐久性等方面已经不能满足要求,所以需要对结构进行加固改造。在进行既有建筑结构加固改造之前,需要正确地、客观地对既有建筑结构的可靠性进行评价。为充分考虑到影响可靠性因素间的相关性,本研究引入网络分析法(ANP)进行权重的计算,然后建立影响建筑结构可靠性因素的模糊隶属矩阵,从而对既有建筑结构的可靠性大小做出有效的评价。最后以某既有混凝土结构进行实例分析。结果表明:该评价模型能够对既有混凝土结构的可靠性进行较准确的评价。Due to the influence of surrounding environment, life expectancy, etc. on building structure, some of the existing building structures have been unable to meet the requirements in terms of safety, applicability and durability, so it is necessary to reinforce and reconstruct the structure. Before the reinforcement on existing building structures, we need to correctly and objectively evaluate the reliability of existing building structures. To take the correlation of the factors which affect reliability into consideration,this paper introduced the analytic net- work process（ANP）to calculate the weight,and then established the fuzzy membership matrix of all the factors affecting the reliability of building structure to make effective evaluation of building structure reliability. In the end, the case analysis on an existing concrete structure showed that the evaluation model can evaluate the reliability of existing concrete structures correctly.
