| Abstract: | According to the features of structure microtremor,and in view of the advantages of ITDmethod,we suggest to use the ITD method in combination with the random decrement techniqueto process and analyze the microtremor data. The model parameters of a frame structure are iden-tified by computer simulation.This method is proved to be practicable and convenient in testing,simple in data processing and highly accurate as well as effective in identifying model parameters.Some applied problems are also discussed. |
