This paper presents techniques which employ frequency response and wavelet analysis to identify damage in soils. Experimental data is obtained by dynamic centrifuge modeling. Dynamic centrifuge model experiments generate complex data. Harmonic wavelet analysis provides a good way to analyse them. In this paper the experimental technique will be explained along with typical time-frequency maps. With harmonic wavelet analysis, the signal features that cannot be observed from classical Fourier analysis were seen. Harmonic wavelet analysis provide a new insight into the boundary effects in the Equivalent Shear Beam (ESB) model container used in the experimental work.
