説明
The effects of the natural frequency ratio n_θ/n_x of the across-wind to the torsional vibration on wind-induced responses of a high-rise building has been investigated in wind tunnel tests using a multi-degree-of-freedom aeroelastic model with a side-span ratio of 2 and an aspect ratio of 5. The across-wind response displacement increases steeply as the natural frequency of across-wind vibration close to that of torsional vibration. This phenomenon is caused by the increasing natural frequency component of torsional vibration in the across-wind direction. It is also inherent in motion-induced wind forces in the across-wind direction accompanied by the torsional vibration. However, n_θ/n_x has small effects on the aerodynamic damping ratios and the motion-induced wind forces in the across-wind direction. The difference in the wind response in the across-wind direction due to changing n_θ/n_x is generated by the difference in the magnification factor in the across-wind direction.
