| 摘 要： | 某超高层建筑总高度492m，风致振动将控制结构的荷载和舒适度。为减小风振响应，提高结构舒适度，拟在第90层设置两个相同调频质量阻尼器。将该超高层建筑简化为14质点多自由度体系，利用高频天平实验结果，在时域内计算了结构在受控与不受控情况下的风振响应，分析了调频质量阻尼器的控制效果，给出了设计方案。

| Abstract: | The analysis indicates that wind induced accelerations of a real super tall building with a height of 492 meters may exceed the criteria of comfort acceptability. In order to reduce wind-excited vibration and improve serviceability, two identical tuned mass dampers (TMD) are designed to be installed on the 90th floor.The super tall building is reduced to a 14-degree-of-freedom system. By using the force balance experiment data, the wind-excited responses of controlled structure are calculated in time domain. Taking into account all wind directions the effectiveness of TMD control in two sway directions is analyzed in the end. |
