台风下香港K11大楼风振晌应实测及分析

The full-scale measurement of typhoon effects on Kll 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.
