Abstract
Earthquakes are troublesome events that may affect civil structures, eventually causing human and financial losses. The strategy of increasing the resistance of structures by increasing the strength of their members implies increased production costs. Furthermore, high stiffness causes high acceleration, which can be harmful to occupants. One alternative is to use resonators in order to reduce the propagation of vibration in such structures. This paper proposes a periodic resonator distribution in a tall building using an optimization strategy (which maximizes the band gap in a beam) in order to obtain an optimal resonator distribution. Displacement transmissibility has been evaluated for several floors and maximum displacement, maximum acceleration, and RMS acceleration have been assessed. It is shown that using periodically distributed resonators is better than using a single resonator at the top of the building.
