- By making use of the time dependent covariance and cross covariance formula which used to calculate the non - stationary response under earthquake random excitation and deduced by xiyuan zhou and hu in 1965 , the covariance and cross covariance formula of the four envelope models was deducted and the result of four models compared
本文通过应用周锡元、胡聿贤在1965年提出的计算地震动随机激励作用下非平稳响应的时变自相关方差和时变互相关方差公式,分别推导了四种包线函数模型的时变自相关方差和时变互相关方差表达式,并比较了四个模型的结果。
