Notes on power spectrum density and wind-velocity PSD;

Based on the relationship between the wind pressure spectrum and the wind speed spectrum,the pulsating wind load in random of the aqueduct across the Yellow River was simulated with a series of cosine functions by the decomposition of cross spectral density matrix.

Because of the nonlinear character of wind load, the spectrum of the wind load is in correspondence with the second order wind spectrum.
