摘　　要：利用时间序列法中的ＡＲ或ＡＲＭＡ模型得到的脉冲传递函数的特点，提出了由传递函数求出结构动力特性的方法．同时，通过分析实验钢筋混凝土梁的振动信号。The authors have made an analysis of the characteristics of the AR/ARMA models in the time series method and the characteristics of the derived pulse transfer function,and have developed a method to derive the dynamic features of stracture from the transfer function. Meanwhile,by analyzing the vibration signals of the tested reinforced concrete beam,have been found the effects of the failures on Green function,and the initial diagnosis factors of failures formed on that basis.
