Abstract：A particle tuned mass damper was proposed by hanging a particle damper on a main structure through a string. It combines a widely used tuned mass damper with an efficient particle damper in vibration control area. Thus it is able to increase the robustness of damping performance within a wider frequency band. Here, an approximate numerical simulation method for particle tuned mass dampers was proposed based on an equivalent priciple to take a multi-particle damper as an equivalents single-particle damper. The method to determine the corresponding system parameters was also introduced. A series of shaking table tests of a single DOF structure attached with a particle tuned mass damper under seismic imputs were performed. A comparative study showed that the simulation results agree well with the test ones, so the proposed simplified method can be used to simulate vibration reduction control effects of particle tuned mass dampers.
