Structural dynamic analysis using wavelets

In this paper, wavelet approach is studied to determine the torsional natural frequencies of a simple discretized structure excited by white noise, emulating environmental conditions. In this work, the implementation of this approach is described and the analytical results of one case are compared with the frequencies determined using Fourier analysis. Results have shown a good agreement between the values reported by Fourier analysis and the obtained by using Wavelet functions. (paper)
