“…The cross-wind peak acceleration is reduced by 9.91% where the natural frequency is increased by 8.55% in the Y direction. These results are in accord with the fact that the level of the wind-induced vibration can be assumed to be inversely proportional to the natural frequency of the building (Tallin, Ellingwood 1984;Griffis 1993).…”

“…It is known that the level of the wind-induced vibration of a high-rise building with a natural frequency range of 0.1~1.0 Hz can be assumed to be inversely proportional to the natural frequency of the building (Tallin, Ellingwood 1984;Griffis 1993). Tallin and Ellingwood (1984), Chan and Chui (2006), and Chan et al (2009) have proven that the wind-induced response can be reduced by increasing the natural frequency of a building.…”

A variety of methods have been applied to reduce the effect of the wind-induced vibration of a high-rise building as the excessive wind-induced vibration at the top of a high-rise building can cause physical and psychological discomfort to the user or the residents. For structural engineers, the most effective approach to control the wind-induced responses of high-rise buildings would be to control the stiffness or natural frequency of the building. This paper presents a practical design model to control the wind-induced responses of a high-rise building. In the model, the stiffness of a high-rise building is maximized to increase the natural frequency of the building by the resizing algorithm. The proposed design model is applied to control the wind-induced vibration of an actual 37-storey building during the initial stage of its structural design.

“…Previous studies have reported the across‐wind responses of supertall buildings often exceed the along‐wind responses, and sometimes they can possibly reach several times of the along‐wind responses . And torsional responses may not be ignored in serviceability design of skyscrapers, as the habitants are more sensitive to torsional motion than translational motion in some cases . Kareem pointed out that the torsional motion may even be further amplified in asymmetric buildings as a result of inertial coupling.…”

Summary Ping An Finance Center with a height of 600 m and 118 storeys, located in Shenzhen, is currently the second tallest building in China. This paper presents a comprehensive study of wind effects on the supertall building through wind tunnel testing and field measurement. The wind‐induced loads and pressures on the skyscraper were measured by high‐frequency force balance technique and synchronous multipressure sensing system, respectively. In the wind tunnel study, a whole range of characteristic properties, including mean and r.m.s force coefficients, power spectral densities, coherences, correlations, and phase‐plane trajectories, wind‐induced displacement, and acceleration responses were presented and discussed. In addition, a field measurement study of the dynamic responses of Ping An Finance Center was conducted during a tropical cyclone, which aimed to verify the design assumptions and further the understanding of the dynamic properties and performance of the 600‐m‐high supertall building, including natural frequencies, damping ratios, and wind‐induced structural responses. Then, the serviceability of the skyscraper is assessed on the basis of the experimental results and field measurements. The outcomes of this combined model test and field measurement study are expected to be useful for the wind‐resistant design of future supertall buildings.

“…acceleration and jerk, is quite significant. Considering also that in a tall building the occupants are more sensitive to torsional motion than translation motion (Tallin and Ellingwood, 1984), their comfort can be affected by an underestimation of the dynamic response if the higher modes of vibration are neglected (Huang and Chen, 2007).…”
