Abstract:
In order to study natural wind property, long-term observation results of wind field were analyzed. Based on the site observation, wind rose plots of annual maximum 10 min mean wind velocity at 10 m and 20 mwere given. 18 series of record of strong wind(75 hours totally)were selected to calculate turbulence intensity, wind velocity profile parameters and shear wavevelocity. Wind velocity spectrum was calculated and compared with Von Karman spectrum and Eurocode spectrum. The statistics of turbulenceintegral scale in primary wind direction was obtained and vertical correlation of wind field was analyzed. The results show that the measured turbulence intensity is a little higher than empirical value. Wind velocity profile parameters are scattered and the mean values differ from values recommended by load code. The measured wind velocity spectrum matches well with Von Karman spectrum and Eurocode spectrum.
