Research on the Vibration Control for Pedestrian Bridge with TMD

According to the working principle of the Tuned Mass Damper(TMD),the finite element model of the Linkuo Road pedestrian flyover is established,then,based on it,the dynamic response of the structure is analyzed to get the design parameters of the TMD.The on-site dynamic tests were done before and after the installation of TMD under the resonance frequency load case.The comparison of the data from the tests shows that TMD reduced the vibration amplitude dramatically.This work could be a useful reference for the similar projects.
