Owing to the lack of recorded data and the randomness of earthquake ground motion that may be experienced by structure in the future, usually it is difficult to obtain recorded data which fit the requirements (site type, epicenteral distance, etc.) well. Therefore the artificial seismic waves are widely used in seismic designs, verification of seismic capacity and seismic assessment of structures. With the emergence of wavelet transformation as a powerful tool of time–frequency analysis in recent years, it has become possible to account for frequency non-stationary behavior more conveniently. The main target of this paper is to present a new method which apply advanced time-frequency analysis, best basis search algorithm, that uses wavelet packet to generate more artificial accelerogram which are compatible with target spectrum. Application of this method for some Iranian earthquakes is presented to compare actual and synthetic accelerograms to each other to demonstrate the effectiveness of model.
