摘要
对一类阶梯过程的模型进行定义,提出单位时间内的平均跳跃次数和跳跃度分布函数,给出产生该阶梯过程的样本函数.应用一次二阶矩法近似计算,得到了结构可靠性和可靠度设计的表达式系数.
A model of step process was defined,and avenue jump frequency and distributed function of jumping degree were given in this paper,and the sample function of step process was offered as well. Applying of approximate calculation with first-order second-moment method, the expression coefficient of structural reliablity and reliability design was obtained.
