Simulations of non-stationary frequency content and its importance to seismic assessment of structures.
To verify the importance of the non-stationary frequency characteristic of seismic ground motion, a joint time frequency analysis technique of time signals, called chirplet based signal approximation, is developed to extract the non-stationary frequency information from the recorded data. The chirpl...
