Inerter‐based dampers (IBDs) have been proposed to enhance the efficiency of conventional tuned mass dampers (TMDs) in controlling wind‐induced vibration of civil structures recently. In this paper, four different IBDs, with each featuring a specific combination of dashpot–spring elements in series or in parallel with the inerter device, are applied to control the vortex‐induced vibration (VIV) of long‐span bridges. The governing equations of the bridge–IBD system under the effect of VIV are established, and the strategy to optimize the IBD parameters is proposed. The performances of different IBDs in terms of mitigating the VIV response of the deck, the stroke of mass block, the static deformation of spring due to gravity, the reaction force of IBDs on the bridge deck, and the robustness of the system (the control efficiency against the deviation of design parameters from their optimal values) are systematically evaluated and compared. Through this comparative study, the superiorities of IBDs to conventional TMDs in bridge VIV control are illustrated, and two feasible layouts of IBDs that are suitable for bridge VIV control are suggested. On the basis of these results, the guideline for VIV‐resistance design of long‐span bridges with the help of IBDs is also proposed.

基于惯性阻尼器的大跨度桥梁涡激振动控制性能评估：一项比较研究

最近提出了基于惯性的阻尼器（IBD），以提高传统的调谐质量阻尼器（TMD）的效率，以控制民用建筑的风振。在本文中，四个不同的IBD用于控制大跨度桥梁的涡激振动（VIV），每个IBD都与惯性装置串联或并联。建立了桥梁-IBD系统在VIV作用下的控制方程，并提出了优化IBD参数的策略。在减轻甲板的VIV响应，质量块的行程，由于重力引起的弹簧的静态变形，桥梁甲板上IBD的反作用力方面，不同IBD的性能，系统地评估和比较了系统的鲁棒性（针对设计参数偏离其最佳值的控制效率）。通过这项比较研究，说明了桥梁VIV控制中IBD相对于传统TMD的优势，并提出了两种适用于桥梁VIV控制的IBD可行布局。根据这些结果，还提出了在IBD的帮助下大跨度桥梁抗VIV设计指南。
