The performances of traditional tuned mass damper (TMD) intended for suppressing the vortex-induced oscillation of bridges were invesitgated. In order to improve the robustness of traditional TMD, multiple tuned mass dampers (MTMD) theory was proposed to design TMDs. Furthermore, a new damper, namely the eddy current damper, was developed to repalce traditional oil damper as the damping producer of TMD, so the fatigue life-span of TMD was greatly extended. The parameter design of MTMD was realized by making use of genetic algorithm. And the results of comparison between TMD and MTMD have indicated that MTMD is superior to TMD, when their effectiveness and robustness are of equivalent importance in design. Both experiments and engineering practice of eddy current TMD were successfully conducted, showing a promising future of eddy current TMD in the field of bridge vibration control.
