Theory and application of wavelet transform method for measuringdynamic characteristics of high-rise buildings
Li Hong · Journal of Nanjing University · 2002
A fundamental idea and an analytical method of using wavelet transform method for measuring dynamic characteristics of high rise buildings were presented. The character of multi resolution of wavelet transform is utilized, and the structural damping ratio is analyzed with a method combined wavelet transform with Fourier transform method. As applications of this method, several high rise buildings in Shanghai were measured and the dynamic parameters of the buildings were obtained. The results show that the accuracy of the method to analyze damping ratio by wavelet transform is higher than other methods.
