This technical note presents an analytical and experimental study on the effectiveness of tuned mass damper (TMD) to suppress a wind-induced coupled flutter of bridge deck. In the analysis, Theodorsen's aerodynamic forces are assumed to act on a bridge deck model. Parametric calculations indicate that critical velocity of the coupled flutter can be increased appreciably by TMD. Wind tunnel test is also performed and confirmed the effectiveness of TMD.
