Field Measurement of Strong Wind Speed of Normal Climate on Top of Shanghai World Financial Center
摘要
Abstract
The mean and fluctuating wind speed data of strong wind of normal climate measured on the top of Shanghai World Financial Center with a height of 492 m were analyzed. Mean wind speeds in different intervals of 3 s, 10 min and 1 hour were separately computed. The results showed that the averaged mean wind speed ratio between 10 min mean wind speed and 3 s maximum mean wind speed was approximately 0.876 8. The formulas for the ratios were then derived by using curve-fitting technique. The turbulence intensity, gust factor were also computed based on the measured data. The results indicate that both turbulence intensity and gust factor decrease with the increase of mean wind speed. In addition,the power spectral densities of fluctuating wind speeds are in agreement with the Von-Karman spectrum.关键词
