As the number of long-span bridges continues to grow, wind-induced vibration issues have become increasingly intensified. Among them, flutter is a serious wind-induced vibration that can lead to bridge collapse. To address this problem, this paper proposes inerter-based dampers as a solution for flutter control and compares their performance to tra...

... stiffening girder of the bridge is a flat streamlined box girder, and the total width of the bridge deck is 32.5 m with a height of 3 m. Table 3 provides the parameters for the Jiangyin Bridge. To determine the critical flutter wind speed solution for the bridge-MISD (inerter-based damper) system of the Jiangyin Bridge, the four vibration modes of the bridge were utilized. ...Citations
... This inertia can exert a certain damping effect, thereby optimizing vibration suppression for different modes by comparing the frequency response function and the same as dynamic transfer function of the main structure. Feng et al. [109] showed that the use of IBDs including TMDI is a promising method for controlling the chattering vibration of large-span bridges, and based on this, eight different IBDs including TMDI were proposed and optimized by comparative study of simply supported beams. In bridge seismic mitigation, TMDI has different vibration amplitudes not only longitudinally but also transversely. ...
Tuned mass damper inerter (TMDI) is a device that couples traditional tuned mass dampers (TMD) with an inertial device. The inertial device produces resistance proportional to the relative acceleration at its two ends through its “inertial” constant. Due to its unique mechanical properties, TMDI has received widespread attention and application in the past twenty years. As different configurations are required in different practical situations, TMDI is still active in the research on vibration control and energy harvesting in structures. This paper provides a comprehensive review of the research status of TMDI. This work first examines the generation and important vibration control characteristics of TMDI. Then, the energy harvesting performance of electromagnetic tuned mass damper inerter (EM-TMDI) is discussed. This work emphasizes the formation of a passive dynamic vibration absorber by coupling traditional TMD with inertial devices. This paper also summarizes the design and implementation of optimal vibration control and energy harvesting for TMDI. Furthermore, this paper details the applications of TMDI in the fields of bridges and building engineering. Finally, this paper summarizes the necessity of research on tuned mass-damper-inertia, the challenges faced currently, and future research directions, such as control of parameters in electromagnetic energy harvesting TMDI systems and low-cost TMDI.
