| 摘 要： | 根据钢筋混凝土结构的可分性，将钢筋混凝土结构分为梁、板、柱、地基基础、围护系统和结构整体性6个相对独立的部分。结合专家经验和已有研究成果，按照各自的准则和指标，构造各项目隶属函数来描述其可靠性的分级，建立各项目模糊关系矩阵。根据层次分析法原理，确定影响其可靠性的各因素权重，提出了钢筋混凝土结构可靠性模糊综合评估新方法。该评估使已有建筑物可靠性鉴定工作更加合理，并为建立相应的专家系统奠定了基础。

| Abstract: | According to the basic hypothesis of separation of reinforced concrete structure,the evaluated structure is divided into six relatively independent parts: beam,column,slab,foundation,embosom system and structural integrity.Taking expert's experiences and research into account,the classification of each component's reliability is described by building its function of membership on the basis of their standard and index,and then the component's fuzzy relationship matrix is established.The analytic hierarchy process and method of fuzzy comprehensive evaluation determine the factor's weight that influences the structural reliability.Correspondingly,the fuzzy comprehensive method of structural reliability evaluation is provided,which makes the reliability appraisal of existing building more reasonable. |
