Abstract:: In order to detect the damage degree,the discount of stiffness is regarded as the damage degree index and the frequency change rate is regarded as the parameter of the damage degree detection. The short time Fourier transform is used to extract the rate of frequency change of acceleration response which is from the model of matlab,then the function between the index of damage degree and the rate of frequency change is established. Thus the damage degree would be detected according to the rate of frequency change of the damaged structure. The data of shaking table test which from Tongji University has demonstrated its accuracy and availability. The result shows that the damage degree is very similar between the damage degree detection and the actual damage degree.
