“…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 et al [11] analyzed the field measurement data of wind-excited vibration responses of two skyscrapers (393 and 432 m in height) during Super Typhoon Mangkhut. Li Z.N.…”

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.

“…The dynamic performance of high-rise buildings is susceptible to the wind-induced response. [15,16] Continuous efforts have been made to understand their dynamics. Zhou et al [17] monitored the displacement of a high-rise building under construction by using ground-based real aperture radar and wavelet analysis technology, which shows that this method has high accuracy.…”

Skyscrapers are wind-sensitive structures due to their large slenderness ratio and good flexibility. Understanding the wind characteristics and wind-induced response from the actual data provides first-hand information for wind resistance design. This paper reports the wind properties and dynamic performance of a 632 m high-rise building in Shanghai during the passage of typhoons Jongdari and Rumbbia. Field measurements obtained from the structural health monitoring system include acceleration and wind speed. The data analysis of turbulence intensity, turbulence integral length, and gust factor are compared and discussed. For the identification of dynamic characteristics, the stochastic subspace method and enhanced frequency domain decomposition method are employed to identify the modal parameters. Besides, the comfort assessment using peak value and root mean square of accelerations is compared with different standards. Studying the wind characteristics during the passage of typhoons and their impact on high-rise buildings in a metropolis is expected to gain an insight into the dynamic mechanism of high-rise buildings and collect a database for wind resistance design in typhoon-prone regions.
