“…Another limitation of a TMD is the size of the tuned absorber mass. In an attempt to increase the performance of the TMD without incurring the problems noted above, active and semi-active TMD (ATMD and SATMD) systems have been proposed [4][5][6][7]. To overcome the limitation of the TMD mass, various seismic isolation concepts using TMD related principles have been extended to convert a structural system into a TMD system by specially designing the structural system [8][9][10][11][12][13][14][15][16].…”

SUMMARYSeismic performance attributes of multi-story passive and semi-active tuned mass damper (PTMD and SATMD) building systems are investigated for 12-story moment resisting frames modeled as '10+2' stories and '8+4' stories. Segmented upper portion of the stories are isolated as a tuned mass, and a passive viscous damper or semi-active resetable device is adopted as energy dissipation strategy. The semi-active approach uses feedback control to alter or manipulate the reaction forces, effectively re-tuning the system depending on the structural response. Optimum TMD control parameters and appropriate matching SATMD configurations are adopted from a companion study on a simplified two-degree-of-freedom (2-DOF) system. Statistical performance metrics are presented for 30 probabilistically scaled earthquake records from the SAC project. Time history analyses are used to compute response reduction factors across a wide range of seismic hazard intensities. Results show that large SATMD systems can effectively manage seismic response for multi-degree-of freedom (MDOF) systems across a broad range of ground motions in comparison to passive solutions. Specific results include the identification of differences in the mechanisms by which SATMD and PTMD systems remove energy, based on the differences in the devices used. Additionally, variability is seen to be tighter for the SATMD systems across the suites of ground motions used, indicating a more robust control system. While the overall efficacy of the concept is shown the major issues, such as isolation layer displacement, are discussed in details not available in simplified spectral analyses, providing further insight into the dynamics of these issues for these systems.

“…The control input u considered here is the force acting on the main mass, which is suitable for the targets of this paper. Our problem setting is different from that of the active tuned mass damper (ATMD) [16][17][18] where the control force acts on a TMD that has a comparatively large mass.…”

“…There are two types of active vibration suppression control methods to avoid the abovementioned difficulty. One is the skyhook control method [5][6][7][8][9][10] and the other is the multiple-degree-of-freedom (MDOF) approach [11][12][13][14][15][16][17][18][19].…”

SUMMARYThis paper considers a vibration suppression control method using feedback for a mass-spring-damper system with a tuned mass damper. For vibration suppression, we adopt the interconnection and damping assignment passivity-based control, whereby the system is transformed to a system with a skyhook damper with an artificial structure matrix. The feedback law includes no accelerometer signal and uses only information on relative displacements and velocities. The proposed control method can simultaneously suppress the influences of the floor vibration and the disturbance force acting on the main body. A guideline for choosing parameters of the desired system is shown. The proposed method can be easily extended to nonlinear cases, which is demonstrated for a nonlinear-spring case. We also show the input-to-state stability property of closed-loop systems for linear cases and nonlinear cases.

“…The results suggested that the design of an optimal ATMD required at least a parametric study to select the ATMD parameters. Furthermore, common feedback control methods using displacement, velocity, complete and acceleration feedback for the ATMD have been studied by many researchers [3][4][5][6]. However, fully active systems may require significant power sources and entail implementation complexity, often beyond a level, which is available or manageable.…”

SUMMARYPassive and Semi-Active Tuned Mass Damper (PTMD and SATMD) building systems are proposed to mitigate structural response due to seismic loads. The structure's upper portion self plays a role either as a tuned mass passive damper or a semi-active resetable device is adopted as a control feature for the PTMD, creating a SATMD system. Twodegree-of-freedom (2-DOF) analytical studies are employed to design the prototype structural system, specify its element characteristics and effectiveness for seismic responses, including defining the resetable device dynamics. The optimal parameters are derived for the large mass ratio by numerical analysis. For the SATMD building system the stiffness of the resetable device design is combined with rubber bearing stiffness. From parametric studies, effective practical control schemes can be derived for the SATMD system. To verify the principal efficacy of the conceptual system, the controlled system response is compared to the response spectrum of the earthquake suites used. The control ability of the SATMD scheme is compared to that of an uncontrolled (No TMD) and an ideal passive tuned mass damper (PTMD) building systems for multi-level seismic intensity.
