Abstract
In this study the wavelet-based analysis technique is proposed for analyzing its time-frequency characteristics, and identifying its maximum dynamic loads with genetic algorithm. The signals extracted by wavelet analysis are furthermore used for estimating the modelling parameters and loads. It is also indicated that the load amplitudes estimated with the extracted data by wavelet analysis can provides more detailed and finer information than those by Fourier analysis technique. This study is a valuable reference for investigating the vibrating source rule and predicting the dynamic response of powerhouse structures.
