Abstract Due to the aerodynamic interference of two closely-spaced linked high-rise buildings, large out-of-phase vibrations of two buildings may be induced at across-wind direction. Tuned mass-damper-inerter (TMDI) is employed to mitigate wind-induced responses of the linked buildings. The linked buildings with TMDI takes advantage of the large relative motion between the two terminals of the inerter to reduce wind-induced responses of the individual building. Firstly, the motion equation of the linked buildings with TMDI under wind loads is presented. Secondly, synchronous multi-point pressure measurement wind tunnel tests for two linked buildings with 268 ​m (the building-1) and 210.2 ​m heights (the building-2), respectively, are carried out to obtain their wind loads. Finally, wind-induced responses of the linked buildings with TMDI are analyzed and are compared with the responses of the buildings with tuned mass damper (TMD) and without any control device to demonstrate the advantages of the TMDI. The analysis of the case indicates that TMDI has better mitigation effects than TMD, even if the mass of TMDI is one third of the TMD. TMDI can effectively reduce the acceleration responses of both the buildings for all wind directions, and yet fail to mitigate displacement responses of the building-2 at few wind directions.

基于TMDI的连接高层建筑风振控制研究

摘要 由于两座相邻的高层建筑之间的空气动力干扰，可能会引起两座建筑物在横风向产生较大的异相振动。调谐质量阻尼器惯性器 (TMDI) 用于减轻连接建筑物的风致响应。与 TMDI 相连的建筑物利用惰轮的两个终端之间的较大相对运动来减少单个建筑物的风致响应。首先，给出了风荷载作用下带有TMDI的连接建筑物的运动方程。其次，对两座高度分别为 268 米（1 号楼）和 210.2 米（2 号楼）的相连建筑进行同步多点测压风洞试验，获取其风荷载。最后，分析了具有 TMDI 的链接建筑物的风致响应，并将其与具有调谐质量阻尼器 (TMD) 且没有任何控制装置的建筑物的响应进行了比较，以证明 TMDI 的优势。案例分析表明，即使 TMDI 的质量是 TMD 的三分之一，TMDI 的缓解效果也比 TMD 好。TMDI 可以有效地降低两个建筑物在所有风向下的加速度响应，但在少数风向下不能减轻建筑物 2 的位移响应。
