Abstract
A full-scale measurement of wind characteristics atop a high-rise building (with a height of 115 m) was conducted during the passage of Typhoon Sarika on 18 October 2016. Wind field characteristics, wind speed, and wind direction atop the building were recorded synchronously, and turbulence intensity, turbulence integral scale, gust factor, and power spectrum were investigated. Meanwhile, the time and frequency domain characteristics of the wind field were analyzed. The stationarity test results of Typhoon Sarika at different time steps are researched in a runs test. And the time-frequency analysis of non-stationary samples of fluctuating wind speed are conducted by wavelet transform, the measured data are valuable for the wind-resistant design of high-rise buildings in typhoon-prone regions.
Highlights
With the rapid development of data acquisition system and sensor technology, field measurement of wind characteristics on high-rise buildings under typhoon is an enduring and developing research topic
Fang et al [9] investigated the gust characteristics of near-ground typhoon based on 14 sets of records observed by 4 meteorological stations during 10 typhoons, the results show that the off-sea gust factor at 10 m is 8% higher than the over-land value while other heights show little difference
Lin et al [10] conducted field measurements of two Typhoon cyclones to study the characteristics of the near-surface boundary layer, and found a region-specific wind speed power spectrum and its associated spectrum parameters that can be used for the design of wind-resistant structures in Typhoon-prone regions
Summary
With the rapid development of data acquisition system and sensor technology, field measurement of wind characteristics on high-rise buildings under typhoon is an enduring and developing research topic. The measurements covered the wind field atop the high-rise buildings, the characteristics of internal and external pressure on the building surface, the vibration displacement and acceleration response of high-rise buildings, etc. Lin et al [10] conducted field measurements of two Typhoon cyclones to study the characteristics of the near-surface boundary layer, and found a region-specific wind speed power spectrum and its associated spectrum parameters that can be used for the design of wind-resistant structures in Typhoon-prone regions. Li Z.N. et al [12] conducted many field measurements of dynamic responses and wind-filed characteristics on 5 high-rise buildings located in the coastal regions of Wenzhou, Xiamen and Haikou from 2008 to 2018, by which they investigated wind field characteristics of different geomorphic characteristics under typhoon and the time-domain and frequency-domain characteristics of the fluctuating wind speed acceleration response. The measured building was elected to conduct wind-resistant field measurement and analyze the impact of different inflow wind field types on the wind-induced response of high-rise buildings due to the diverse geomorphic characteristics of the building in different directions
