摘要 在风基本特性的理论基础上,应用Shinozuka方法对大跨结构的广义脉动风进行了模拟,引入快速傅立叶变换(FFT)技术以提高计算效率,同时给出了Matlab程序框架,并把模拟谱与目标谱进行比较验证,两者吻合较好。 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.
