摘要

Based on multimode coupled buffeting theory proposed by Scanlan and passive control theory of multiple tuned mass dampers(MTMD), the multimode coupled buffeting control theory of MTMD for bridges are established in this paper. Multimode participation and aerodynamic coupling among the modes or the modal displacement components in a mode are all taken into account in the formulation. And each TMD can be installed anywhere on the bridge deck. So it is the most comprehensive procedure for buffeting control of bridge with MTMD. Finally, time-domain approach is used to verify the proposed procedure and the results of the presented method agree quite well with those of time-domain approach, which shows that the theory established in this paper is correct.
