Abstract: Tuned Mass Dampers (TMDs) are generally known to be highly effective in suppressing unwanted structural vibrations induced by random environmental loads. In this paper, optimal design parameters of passive and active TMDs are optimized through an advanced optimization algorithm. To validate its performance, the algorithm was implemented to a 10-story shear frame subjected to severe seismic activity and to a 76-story concrete office building subjected to wind-induced vibration. The outcomes prove that TMDs designed with this technique greatly improve the structural system's capacity to resist dynamic excitations, proving to be useful and efficient in enhancing building stability.
