摘要
本文讨论结构应力S(t)在设计基准期[0.T]内变动规律。当应力变动时间间隔是独立同服从x^2—分布的随机变量时,建立x^2更新过程模型,获得x^2更新过程样本函数最大值概率分布的初等函数表达式及最大值S_M的一、二阶矩估计。
In this paper, we discuss the law of structural stress variance during the standard period of the design of [0,T]. Considering the renewal inter-arrival time is x2 distribution, this paper intends to for m the model x2-renewal process and makes the formulas of probability distribution of maximum of x2 -renewal process and estimation of statistical parameter.
