摘要
通过高层建筑气动弹性模型的风洞试验 ,测得模型的顺风向、横风向和扭转风向加速度响应时程曲线 ,并用随机减量技术 ( RDT)分析、计算得到其气动阻尼 。
The time series of acceleration responses in along wind, across wind and torsional directions of tall buildings are obtained by wind tunnel tests of aero elastic model, and the aerodynamic damping ratios are analyzed and evaluated by using the random decrement technique (RDT). The investigation of the experiment provides an approach and reference for evaluation of aerodynamic damping in wind induced vibration of tall buildings.
