某超高层建筑屋面TLD方案设计及性能分析

Scheme Design and Performance Analysis of TLD on the Roof of a Super High-Rise Building

结合珠澳湾世纪中心项目施工总承包工程,对珠澳湾世纪中心A栋调谐液体阻尼器(TLD)设计方案中的阻尼器减振性能进行分析,采用有色噪声作用下的振动台试验,对测得的水箱液面多点响应信号进行分离再采用不同识别方法进行参数识别,得到TLD阻尼器的性能参数。通过在TLD内设置桨柱能够增大模态阻尼比,使建筑物的风振舒适度得到改善,满足相关规范和标准对舒适度的要求。

Combined with the general contract project of Zhuao Bay Century Center Project,the damping performance of the damper in the TLD design scheme of Zhuao Bay Century Center Building A was analyzed.Shaking table test under the action of colored noise was used to separate the measured multi-point response signals of the water tank level and then different identification methods were used to identify the parameters,and the performance parameters of the TLD damper were obtained.By setting OARS in the TLD can increase the modal damping ratio,improve the wind vibration comfort of the building,and meet the requirements of relevant codes and standards for comfort.
