摘　　要：提出一种简便的既有结构体系可靠性鉴定方法,用隶属度对结构构件的可靠度进行了定量的分析,并利用层次分析法确定构件的权重系数,从而得到体系可靠度的鉴定等级隶属度。以钢筋混凝土框架结构体系为例进行了体系可靠性等级的评定,该方法具有合理性和贴近实践的可操作性,对既有结构的鉴定起到很好的指导意义。In order to propose a convenient reliability assessment method for present structure system, the reliability of structure members is quantitatively analyzed through the membership grade, and the weight coefficients of members are determined by the analytic hierarchy process. Then, the membership grade for assessment classification of structure system reliability is derived. As an example, reliability of steel reinforced concrete frame structure system is assessed by this approach, which proves the introduced method is reasonable and feasible in engineering practice. The research is meaningful for reliability assessment for existing structures.
