###### Abstract  
On 18 October 2016, the wind-induced effects of a high-rise building with square section was measured by the monitoring system in Haikou of China during Typhoon Sarika. The wind characteristics stop the building and the time-history responses of the translational and rotational accelerations on different floors were measured by the monitoring system; the first three modal parameters were identified according to the measured acceleration. The results show that the combinations of the cross spectral density function, phase spectrum, and coherence function can clearly judge the phase of the measured floors in the frequency resonance area as well as its modal frequencies at the first three orders. The modal frequencies at the first three orders decrease linearly with the growth of mean wind speed within the range of 0-20m/s. The estimation formula of the modal frequencies of high-rise buildings considering the influences of different wind speeds is put forward, which is expected to fill the gap in the existing specification for the quantitative analysis of the influences of wind-loads on the fundamental frequencies of high-rise buildings. t 2021  
some limitations of the measuring sensors, the rotational measurements are not as widely used as the translational measurements (acceleration, speed, and displacement). The existing research mainly covers the torsion-resistant studies of structures under the actions of controllable load, earthquakes, and wind load. As for the torsion-resistant studies of the reinforced concrete structures under the action of controllable load, many scholars ([PERSON], 2016 [1]; [PERSON], 2014 [2]; [PERSON], 2011 [3]; [PERSON], 2012 [4]; [PERSON], 2016 [5]; [PERSON], 2015 [6]) conducted theoretical and experimental research on both reinforced concrete and steel-concrete composite structures, and acquired a series of achievements. Many scholars (such as [PERSON], 1989 [7,8]; [PERSON], 2000 [9]; [PERSON], 2003 [10]; [PERSON], 2004 [11]; [PERSON], 2010 [12]; [PERSON], 2003 [13]; [PERSON], 2006 [14]; [PERSON], 2002 [15]; XU, 2000 [16]; [PERSON], 2002 [17]; [PERSON], 2004 [18]; [PERSON], et al., 2006 and 2010 [19,20]) have studied the lateral-torsional coupling issues of structures under the actions of earthquakes by the theoretical analysis, finite element model, and vibration tests, and explored the influences of eccentricity \(e/r\), period ratio \(T_{t}/T_{l}\), and the relative torsional response ratio \(\theta_{r}/u\) on structures. They also suggested that the torsional responses of eccentricity \(e/r\) and the period ratio \(T_{t}/T_{l}\) and relative torsional response ratio \(\theta_{r}/u\) to structures should be controlled. While the existing field measurements to the torsional responses of high-rise buildings under the actions of earthquakes were insufficient, which was closely related to the factors of earthquakes such as unpredictability, burstiness, and great destructiveness, these factors also posed a challenge to conducting field measurements of earthquake resistance on high-rise buildings. Studies on the dynamic parameters of high-rise buildings under the influences of typhoons have been conducted by many scholars in recent years, but most involved the translational dynamic parameter identifications of high-rise buildings ([PERSON], 2005 [21]; [PERSON], 2017 [22], 2014 [23], 2004 [24]). Many existing torsion resistance studies analyzed the torsional wind load and the wind-induced responses of structures on the basis of wind tunnel tests and the related theories, while few studies were specially related to the prototype filed measurements of the torsional modal parameters of high-rise buildings under the influences of typhoons. [PERSON], et al. (2013) [25] studied wind-induced torsion vibration of the super high-rise building of Shenzhen Energy Center, and proposed that the wind-induced torsion vibration of the building was sensitive to wind directions, thus it should be considered.
