Abstract: A preliminary strategy of using multiple tuned mass damper (MTMD) system on buffeting control of the Yangpu Bridge are presented in this paper. The MTMD system consists of a set of TMDs which are attached to the center region of the bridge's main span and are symmetrical about the center of the main span as well as about the central line along the bridge span. It is found that the control efficiency of the MTMD system is sensitive to its frequency characteristics, namely, the central frequency ratio and the frequency bandwidth ratio. On the other hand, the damping ratio of the TMDs has less significant effects on the control efficiency. A level-type of TMD has been proposed which requi[r]es less space for installation as compared to the traditional hanging type of TMD. A total of seven MTMD systems which corresponding to seven different mass ratios are designed. Anyone of these seven MTMD systems can be used for the buffeting control of the Yangpu Bridge depending on the required control efficiency and the available budget.
