| Abstract: | In this paper, a new method HHT which is invented to deal with non-linear and non-stationary data is recommended detailedly, and its validity and advantage are also discussed. The application future of HHT in the earthquake engineering is introduced in brief, and then, as an simple example, the amplitude-frequency-time distribution of the El Centro strong ground motion is analyzed by the HHT method and the comparison between the HHT marginal spectra and Fourier spectra is also made. |
