comparison of modal parameters of multi-story building obtained by wavelet transform of different response histories

Wavelet transorm has been used extensively as a tool for system identification and / or damage detection of structures. The main idea in its application to structures is to transform the free or forced vibration time history response of the structure to time frequency or time scale domain by application of selected wavelet function through continuous wavelet transform CWT.
