结构应力S(t)的Erlang复合更新过程最大值分布

Probability Distribution of Maximum of Stress Erlang Renewal Square Wave Process S(t)

讨论结构在设计基准期［０，Ｔ］ 内应力变动规律，考虑应力变动时间间隔是独立同服从Ｅｒｌａｎｇ 分布的随机变量，建立Ｅｒｌａｎｇ 复合更新过程模型，获得结构应力Ｓ（ｔ） 的Ｅｒｌａｎｇ 复合更新过程样本函数最大值ＳＭ 的概率分布。

Discusses the law of structural stress variance during the standard period of the design of [0,T].Considering the renewal inter arrival time is Erlang distribution,intends to form the model Erlang renewal square wave process and makes the formulas of probability distribution of maximum of stress Erlang renewal square wave process S(t).
