This paper deals with the design method for a tuned pendulum damper(TPD)to suppress the wind induced coupled flutter of a bridge deck, and deals with the effect of a multiple TPD(MTPD)in order to improve the robustness of the single TPD. The design method for TPD is established using control theory on stability for the coupled flutter which is a self exciting vibration system related to asymmetry of the stiffness and damping matrices. This method is extended to the design for MTPD. Thus, it is confirmed that the robustness against tuning error of TPD's frequency and damping is increased by MTPD because of the decreasing of the response of the deck torsional mode and the changing of the phase of the flutter system compared with the single TPD.
