Two high-rise residential buildings in Hong Kong, among the tallest ill the world, were equipped to monitor their wind-induced dynamic response. The effects of typhoon Imbudo and typhoon Dujan on the buildings are presented in detail. Upcrossing analyses performed oil the acceleration data indicate the wind-induced response of the buildings during typhoons Imbudo and Dujuan follow a Gaussian distribution. Natural frequencies of vibration in two orthogonal translational and torsional directions are estimated by empirical, numerical, and experimental techniques. A comparison between these natural frequencies reveals that experimental values are higher than empirically or numerically predicted values. This finding suggests that tall, reinforced concrete (RC) buildings in Hong Kong are stiffer than similar buildings in other Countries. (c) 2005 Published by Elsevier Ltd.
