摘要 在考虑随机信息、模糊信息的基础上,采用正态隶属度函数构造出具有重叠关系的结构损伤状态模糊集;通过引入专家状态相似矩阵,建立以欧式贴近度最大为目标的数学模型,进一步求解得到最优隶属度函数;以此为基础采用择近原则对结构损伤状态进行评估。将文中构造的算法嵌入到结构健康监测系统中,可为现役结构的健康诊断提供依据。算例表明,文中建立的方法行之有效并且具有很好的通用性,具有实际工程应用价值。 We introduce an effective,general and practicable assessment method that can handle many types of uncertainties,including those due to ambiguity,vagueness and fuzziness that are statistically indescribable.Sections 1 and 2 of the full paper deal with essentially four things:(1) our method improves damage condition assessment by performing fuzzy pattern recognition using fuzzy sets;(2) we use healthy observations to construct a fuzzy set representing healthy performance characteristics;additionally,the bound...
