| 摘要： | The present work proposes a new multituned mass damper inerter (MTMDI) system to reduce the wind-induced responses of linked high-rise buildings. In the proposed system, two high-rise buildings are linked to each other by two tuned mass-damper-inserters (TMDIs). Such a system exploits the large relative motion between two-linked buildings (TLBs) by using an inerter to reduce the individual building's acceleration responses. In this paper, a model of the TLBs with the MTMDI under wind loads is proposed, and the model involves three additional scenarios, including a single TMDI in TLBs, each building separately equipped with TMDIs and tuned mass dampers (TMDs). Wind-induced responses of the TLBs are estimated based on wind loads obtained from wind tunnel tests of synchronous multipoint pressure measurements. The performance of the MTMDI system with optimal parameters obtained by the multiobjective optimization method is compared with that of the other three scenarios. The results demonstrate the effectiveness of the optimal MTMDI system in terms of mitigating acceleration responses with less requirement of total mass, which makes the MTMDI system more efficient and an attractive alternative to the other scenarios.
