摘要
本文根据失效率函数h(n)讨论了假定疲劳寿命服从对数正态分布的不合理之处,并在假定疲劳寿命服从威布尔分布的基础上导出钢桥构件疲劳可靠度的计算式。
Based on the function of failure rate h(n), this paper discusses the unreasonableness of presuming that fatigue life is subjected to normal distribution and formulates the equations for computing the fatigue reliability of steel bridge components on the presumption of fatigue life being subjected to Weibull distribution.
