Abstract

Multiple tuned mass dampers (MTMDs) can effectively control the floor vertical vibration caused by pedestrian’s loads. The research on MTMD parameter optimization has been mature, but there is no effective method in MTMD position optimization. Based on the dynamic coupling equation, the participant approach of the position-related terms in the MTMD vibration control was investigated. The finite element method and the modal analysis method were used to construct the combined optimal method of MTMD parameter and location. Comparison of the acceleration for a floor equipped with MTMD designed by the combined and the parameter optimization shows that the proposed MTMD has better damping performance than the parameter optimal MTMD.
