Y.; 鄭啟明; Cheng, C. M.; Sun, D.淡江大學土木工程學系淡江大學淡江理工學刊=Tamkang journal of science and engineering 3(1), pp.1-13An analytical model is presented to examine the performance of multiple tuned mass dampers (MTMD) for the long span bridges subjected to wind excitation. The reduction of dynamic response and the increase of the flutter velocity by the attachment of the MTMD to the bridge are discussed. Through a parametric analysis, the characteristics of MTMD are studied and the design parameters including mass, damping, bandwidth, and total number of TMDs are proposed. A comparison of effectiveness between a single TMD and MTMD is also presented in this paper. The results indicate that the MTMD, designed with the recommended parameters, is not only more effective but also more robust than the usual single TMD agains
