Active Tuned Mass Dampers for Control of Seismic Structures
Authors: , ,
Abstract: Structural control has been implemented to major structures that are exposed to excitations which have random vibration behavior including strong winds, traffics and especially ground accelerations resulting from strong earthquakes. It is possible to apply passive and active control methods. In passive, structures are controlled via additional mechanical components, while and external force generating by a powered motor is needed for active control. In the practice of this study, active tuned mass dampers (ATMDs) are used to reduce vibration and responses of structures. The parameters of Proportional-Integral-Derivative (PID) type controllers used in ATMD was found via trial-error method, while mechanical properties of mass damper are optimized via metaheuristic algorithm called Jaya Algorithm. The results were compared with passive tuned mass damper (TMD) and uncontrolled structure. The tuned ATMD is effective to reduce structural vibrations better than TMD. In future studies, both mechanical and controller parameters can be optimized via metaheuristic algorithms.
