中文摘要：

对香港K11大楼开展台风下风振响应实测研究，给出2008年台风北冕（Kammuri）作用下该楼的风振响应实测数据．基于三阶和四阶统计量对其风振加速度的时程数据进行统计分析，评价该大楼的风振舒适度．利用谱分析识别结构的自振频率，与该楼的有限元计算及自振频率经验公式结果进行对比．并通过基于零穿越率的峰值因子法和基于经典极值理论的改进Gumbel法对加速度响应的峰值因子进行计算，结果表明，两种方法所得结果基本一致，而GB50009-2001取值偏低．

英文摘要：

The full-scale measurement of typhoon effects on K11 building in Hong Kong was studied. This paper presented the acceleration data of the building under Typhoon Kammuri in 2008. The acceleration data were analyzed in terms of the third and fourth moments, The occupant comfort of the building under wind-induced vibration was evaluated. The vibration frequencies of the building were identified by spectral analysis technique, and were compared with the finite element method results and empirical results. Both the traditional peak factor method and the improved Gumbel method were applied to estimating the peak factor of wind-induced acceleration response. The peak factor results show good agreement with the other two methods. The values in GB50009-2001 are low.
