| 摘 要： | 将灰色聚类法用于已有建筑物可靠性鉴定中．根据工程实践经验和结构可靠度理论，进行分析比较确定聚类指标、评定等级量化标准及聚类灰类．通过构造白化权函数进行灰色聚类分析．灰色聚类法，不仅能够相当正确地判别结构的可靠性等级，而且在灰色聚类系数矩阵中显示了各样本对于不同鉴定等级的隶属程度．

| Abstract: | In this paper, grey clustering method is introduced into the appraisal of the reliability of existing buildings. According to the experience from engineering practices and reliability theory of building structures, clustering index, quantified criterion and clustering classes are confirmed. Whitenization weight functions are constructed for grey clustering analysis. This method can not only exactly judge the reliability grade of the structure, but also display the subjection of various samples to different grades in grey clustering coefficient matrix. |
