| Abstract: | The earthquake is a great and sudden natural disaster,and the related engineering research has been a hot-point subject in the civil engineering.Its primary problem is the input of seismic motion.Here,through attempting to put the wavelet packet decomposition technique into the artificial seismic synthesis technology and using the good time-frequency localization nature of the wavelet function,a feasible synthetic method for artificial seismic motion is proposed.At the same time,based on the seismic geologi... |
