| Abstract: | The Guangzhou West Tower,which is 432 m high and 103 stories,is the tallest building in South Eastern China.The wind characteristics and wind-induced vibration of this tall building were simultaneously measured when Typhoon Megi affected this tall building.Some results for wind characteristics at about 440 m height were obtained from the statistical analysis on the measured wind data:①The turbulence intensity decreases with the increasing mean wind speed,while gust factor increases with the increased turbulence intensity;②The measured power spectral density of fluctuation wind speed in longitudinal and transversal direction could be fitted very well by Von Karman spectrum.The statistical analyses on the measured wind-induced acceleration response atop the building have shown that the measured natural frequencies are very close to the numerical FEM analyzed results.Finally the relationship between the wind-induced acceleration response atop the building and mean wind speed were obtained from the measured data. |
