［摘要］高耸柔性结构在风荷载作用下易产生较大的振动加速度和变形，随着其在工程中的广泛应用，对高耸结构进行结构风致振动控制以提高其舒适度显得极其重要。针对某旅游观光塔进行风振响应分析，并以塔中的消防水箱作为调谐质量阻尼器系统(TMD)的惯性质量，进行了TMD风致振动控制设计及其振动控制分析。研究结果表明，所设计的悬挂式TMD控制系统可以有效减小顺风向结构风致响应，从而显著提高观光塔的舒适度，并对结构的基底剪力、倾覆力矩、顶部位移等均有较好的控制效果；同时对观光塔横风向风振进行初步验算，判定其不会发生大幅值的涡激振动现象。

Abstract: Due to flexibility of high-rise building subjected to wind excitation, large acceleration and deformation would easily occur. With the increasing of the high-rise building application in engineering, it is important to reduce the vibration and increase the comfortable degree of the high-rise building induced by wind. Numerical analysis on vibration responds of one sightseeing tower was conducted. On the basis of the analysis results and utilizing the fire water tank as the mass block, the tune mass damper（TMD）was designed to mitigate the vibration and investigation on wind-induced vibration control of the sightseeing tower installed with TMD was carried on. The investigation indicated that the designed suspended TMD could effective reduce the vibration respond induced by along-wind and improve the comfortablity of the sightseeing tower. Moreover, the base shear force, overturning moment and top displacement could be decreased effectively by installing with the designed TMD. In addition, the vibration of the tower subjected to across-wind excitation was calculated to demonstrate that the vortex-induced vibration with large amplitude could not be happened for the sightseeing tower. 

Keywords: high-rise building; vibration control of building subjected to wind exciting; tuned mass damper; comfortable degree
