Abstract
This paper presents field measurement results of wind characteristics and structural response of DI Wang Tower during Typhoon Sam, which crossed over the tower on 22 August 1999. DI Wang Tower of 384 m high is located at the dawntown Shenzhen, about 2 kilometresfrom the Hong Kong border. The field measurements were made possIble by a wind and structural-monitoring program jointly developed by The Hong Kang Polytechnic university and China Academy af Building Research. The measured wind data are analysed In this paper to obtain the mean wind speed and directian, turbulence Intensity, gustfactor, prababllity distribution, and wind spectrum. Comments are made on wind characteristics through the comparison, as far as possible, between the measured results and those currently used in Hong Kong. The structural characteristics and response, including natural frequency, modal-damping ratio, translational and torsional displacement and acceleration respanses, Of the tower meosured during Typhoon Sam are also prese...
