Base on FFT method to simulate fluctuating wind and Matlab realization

YUAN Bo;ZENG Minghui;LI Xiazhao;Space Structures Research Center,Guizhou University;  
In this paper,base on basic characteristics theory of the wind and the Shinozuka method to simulate the generalized fluctuating wind of large span structure,at the same time introduced the fast Fourier transform(FFT) technique to improve the calculation efficiency,at last given the Matlab program frame of simulation fluctuating wind and compare the simulated spectra with the target spectrum,the result shows good agreement both the simulated spectra and the target spectrum.
