摘要：
A relational expression of wavelet packet coefficients and power spectrum is derived based on the theories of wavelet packet analysis. The new expression is proposed to compute the power spectrum of wind-induced response of structures. Further, the approach is applied to the power spectral analysis of the response signals of a large-span roof structure, and the accuracy of spectral estimation for stochastic signals is verified.
