Abstract
The stiffness-connection based double tuned mass dampers, referred herein to as the SDTMD, have been proposed in this paper. Specifically, an added stiffness between the structure and smaller mass block in the DTMD was introduced, then forming the SDTMD. In order to obtain the optimum parameters of the SDTMD, an optimum criterion is defined. Employing this defined criterion, the influences of the mass ratio have been scrutinized on the optimum parameters and effectiveness as well as the stroke of the SDTMD. Furthermore, for the purpose of comparison, this study simultaneously investigates the optimum performance of the TMD, DTMD, and the damping-connection based double tuned mass dampers (DDTMD). It is found in terms of numerical results that the effectiveness of the SDTMD is remarkably higher than that of the TMD, DTMD and DDTMD.
