摘要
文献[1]提出了结构可靠性计算前处理的思想,包括失效函数的等价变换和失效函数的简化。针对随机变量服从对数正态分布的情况,本文进一步完善和扩展了文献[1]提出的结构可靠性前处理的思想。考虑了线性相关的情况,并给出了计算验算点及灵敏系数的公式。
The concept of preprocessing for the analysis of structural reliability has been put forward in the literature(1).By taking advantage of the characteristics of the logarithmic normal distribution and simplifying the limit state function,a new method is proposed to further develop and complete the above concept.The linear correlation of random variables is considered and the formulas for computing the checking point and the sensitivity coefficient of random variables are presented.
