摘要
讨论结构在设计基准期［０，Ｔ］内应力出现的规律。考虑应力出现时间间隔是一串独立同服从Ｐｏｉｓｓｏｎ分布的随机变量序列，建立Ｐｏｉｓｓｏｎ更新过程模型，获得结构应力在设计基准期［０，Ｔ］内的最大值概率分布以及结构可靠度和结构当量正态设计表达式。
This paper discusses the law of structural stress appeared during the standard period of the design considering the time interval of the appearance of the stress is a sequence of independent random variables which obey same Poisson distribution,this paper establishes the model of Poisson renewal process.Obtains the formulas of probability distribution of maximum and of the structural reliability and of design of equivalent normal random variable of structural reliability,the standard period [0,T] of the desing.
