围绕自立式高耸结构悬吊式调谐质量阻尼器(Tuned Mass Damper,TMD)减振试验展开研究。首先,以某真实高耸结构为原型,基于欠人工质量模型理论设计了试验模型,并通过数值分析和实测结果验证模型合理性。针对该模型开展了原结构的静、动力试验,进而基于模式搜索算法对数值分析模型进行了修正。最后,进行了自立式高耸结构TMD减振试验,并结合数值模拟对试验结果进行了分析。研究表明,基于模式搜索算法的高耸结构模型修正方法,仅需迭代50次即能收敛,是一种高效的数值模型修正方法;附加TMD后,试验模型阻尼比增加了0.02,可见在自立式高耸结构中采用悬吊式TMD能够有效抑制其振动。
In this paper, vibration control experiment of self-standing high-rise structures with pendulum Tuned Mass Damper (TMD) is studied. Firstly, by using the theory of insufficient-mass model, a scaled model is designed according to a real high- rise structure. And the similitude relationship of the scaled model is validated by numerical simulation and testing data. After that, both the static and dynamic experiments are conducted on this model, and the numerical model is updated based on the pattern search method. Also, a dynamic experiment of the structure with pendulum TMD is presented, and the results are numerically simulated and discussed. The investigation shows that the model updating method, which is based on the pattern search algorithm, can converge within no more than 50 generations, so it is a method with high efficiency. The damping ratio of the scaled model increases by 0.02 after the TMD is installed on its top, so the pendulum TMD in self-standing high-rise structure can mitigate the structure's vibration effectively. The work may offer some reference for the design and application of pendulum TMD in the self-standing high-rise structures.
