Abstract :
Based on harmonic superposition method (WAWS method) under the situation of multiple fluctuating wind speed, the spatial correlation of multi-point and Simiu spectrum were considered. Meanwhile decimation in time Fast Fourier Transform method (DIT-FFT method) was carried on optimizing the speed of wind. Then the fluctuating wind speed long direction of wind was simulated.
