中文摘要：

广州西塔楼高432m共103层，属目前华南地区第一高楼，在台风“鲇鱼”的影响下，对其台风特性及风致结构振动进行了现场同步实测，获得了其风场特性、结构动力特性以及风致结构振动响应等相关结果．结果验证了湍流强度随平均风速增大而减小、阵风因子随湍流强度增大而增大等规律，且实测的顺风向与侧风向脉动风速谱均符合Von Karman谱．通过风作用下楼层顶部加速度数据分析，结果表明测试的结构模态参数结果与有限元分析吻合．通过对此建筑物风场特征和风致振动的同步实测结果分析，讨论了楼顶平均风速和加速度均方根响应之间的关系．上述实测分析结果为超高层建筑设计及相关研究提供了参考．

英文摘要：

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 decrea- ses with the increasing mean wind speed, while gust factor increases with the increased turbulence intensity;② The 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.
