摘要:

To study the adaptability of particle damping technology in seismic control of bridges, a preliminary design principle of a tuned particle damper for continuous viaducts was presented. A 1/10-scale model bridge based on a continuous viaduct was designed. The shaking table tests of the model bridge with and without dampers were conducted using a shaking table array system. The results showed that the preliminary design method of the tuned particle damper can provide a valuable reference for application of particle damping in bridges' seismic control; good prospect for the application of tuned particle damper in seismic control of bridges can be expected; the tuned particle damper can effectively reduce the seismic response of continuous viaducts while the excitation intensity is one of the keys to the performance of the damper; compared with tuned mass damper and tuned liquid damper, the tuned particle damper has a wider control frequency band.
