Abstract: The tuned mass damper (TMD) technique has been implemented in high-rise buildings, observatory towers, building floors, railway bridges and pedestrian bridges against natural and man-made loadings for near 40 years.TMDs can be incorporated into any structure with less interference compared with other energy dissipation devices.Although the design and application of traditional linear TMD systems are well developed, detuning effect and excessive stroke of TMD are the two major problems to be solved.In order to enhance the performance of TMD systems, some researchers have proposed a TMD with semiactive variable stiffness device (VSD).The VSD can be classified into on-off type VSD and continuous type VSD.The continuous VSD is effective in mitigating detuning effect while the on-off VSD is effective in reducing TMD stroke.In this study, a resettable variable stiffness TMD (RVS-TMD) is proposed to combine the advantages of the continuous and the on-off typed variable stiffness TMD.This study numerically simulates the dynamic behavior of a structural system controlled by the RVS-TMD, and compares its control performance with the optimal passive TMD and conventional variable stiffness TMD systems.
