Aiming at the problem of narrow damping frequency band traditional single‐tuned mass damper (STMD), this paper proposes multiple‐tuned dampers (MTMDs) and six different configurations tuned inerter systems (TMDI‐Ⅰ–TMDI‐VI) for vibration suppression optimization. A long‐span steel truss footbridge was selected as research object, a simulation model single‐degree‐of‐freedom pedestrian bridge‐damping system established by Matlab Simulink, effects STMD, MTMD, TMDI under human‐induced excitation were compared analyzed. The results indicate that effect MTMD is better than STMD when self‐oscillating deviated, its robustness further improved with increase in number subunits n . varies greatly, among which TMDI‐III has best robustness, | λ = 5%, rate α still able to 8.3% STMD. can provide theoretical support reduction control large‐span footbridge.
