Multi active tuned mass dampers for earthquake-induced vibration response control of high rise building

This paper discusses the advantages of the multi active tuned mass dampers (MATMD) for vibration control of multi-degree-freedom structures and their distribution masses. The 11-story building having two ATMDs at different story and different ATMD mass under long and short period earthquakes is considered. A structural system with ATMDs using fuzzy logic control was simulated against the ground motion of the earthquakes. The time history of the story displacements and accelerations, and the frequency responses of both the uncontrolled and controlled structures are shown in this study to investigate the effectiveness of multiple ATMDs compared with single ATMD and distributed multiple tuned mass dampers (d-MTMDs). The gained results also present the effect of mass distribution of two ATMDs and their location on the building response that the distributed MATMD with same mass has better performance than the distributed MATMD with different mass and single ATMD in the most earthquake cases.
