摘　　要：为解决超高层建筑在强风作用下遭受涡旋脱落的影响可能会出现大幅振动问题,提出将高性能串并联调谐质量阻尼器惯容器(tuned tandem mass dampers-inerters,TTMDI)系统用于超高层建筑横向风致振动控制。在频域内,推导出超高层建筑-TTMDI系统的峰值响应公式,进而定义优化准则,并采用模式搜索法进行控制装置参数寻优。以某超高层建筑为例,考虑TTMDI系统的不同拓扑形式和总惯容质量比,分别从其控制有效性、刚度和阻尼系数、冲程、惯性力和鲁棒性方面,对TTMDI性能进行评估,并与调谐质量阻尼器(tuned mass damper,TMD),串并联调谐质量阻尼器(tuned tandem mass dampers,TTMD)和调谐质量阻尼惯容器(tuned mass damper-inerter,TMDI)进行比较。数值结果表明:TTMDI具有更好的风致振动控制有效性和鲁棒性;此外,当拓扑或总惯容质量比增大到一定程度时,TTMDI只需要一个连接阻尼;而且,TTMDI系统对总阻尼的需求不到TMDI系统的一半,更易于实现。Here,to solve the problem of large-scale vibration of super high-rise buildings affected by vortex shedding under strong wind,a high-performance tuned tandem mass dampers-inerters(TTMDI)system was proposed to control cross wind-induced vibration of super high-rise buildings.In frequency domain,the peak response formula of super high-rise building TTMDI system was derived,the optimization criterion was defined,and the pattern search algorithm was used to optimize parameters of the control device.Taking a certain super high-rise building as an example,considering different topological forms and total inertia volume mass ratios of TTMDI system,the performance of TTMDI system was evaluated from the aspects of control effectiveness,stiffness and damping coefficient,stroke,inertia force and robustness,and compared with those of tuned mass damper(TMD),tandem-parallel tuned mass dampers(TTMD)and tuned mass damper-inerter(TMDI).Numerical results showed that TTMDI system has better effectiveness and robustness of wind-induced vibration control;when topology or total inertia volume mass ratio increases to a certain extent,TTMDI only needs a connection damping;the total damping requirement of TTMDI system is less than half that of TMDI system,the former is easier to realize.
