Abstract:
Combining the relevant regulation in Chinese, American and Australian load code, the turbulence intensity of wind turbulence, turbulence integral length and turbulence spectra of wind turbulence were compared. The comparative analysis shows that the turbulence intensity deduced from Chinese load code is smaller than that specified in American and Australian load codes. Turbulence integral length adopted in Chinese load code is constant, while that will increase with height increases in American and Australian load code. In the same height, turbulence integral length values in Chinese code intervene in American and Australian codes. In the range of building's natural frequency, turbulence wind velocity spectrum value in Chinese load code is the largest one.
