摘要
当得不到足够的统计数据信息时 ,将结构的不确定参数描述为区间变量 ,结合区间变量的性质 ,定义一种结构非概率可靠性度量指标 ,并对结构系统非概率可靠性进行了深入的研究 ,在区间有限元基础上 ,提出了结构系统失效模式识别和体系非概率可靠性分析的一种有效途径。
A new structural non probabilistic reliability index is defined by describing structural uncertain parameter as interval variable and in light of the algorithm of interval variable, especially when enough statistic data can not be obtained. Based on interval FEM, an effective method of discriminating failure mode and analyzing non probabilistic reliability of structural system by amending stiffness matrix is introduced.
