Abstract In response to the growing need for renewable energy, this paper proposes a new type of Tuned Mass Damper (TMD) to produce electrical power from the unused traffic-induced vibrational energy of structures in addition to its energy dissipative role. The proposed device, called the Tuned Mass Piezo-damper (TMPD), takes the form of a conventional TMD in which the costly damping component is replaced by a series of piezoelectric elements. As a preliminary study, the electric power that can be potentially generated by the TMPD with reference to the energy dissipated by the TMD is computed through a numerical simulation on a footbridge subjected to a harmonic excitation. In addition, a TMPD prototype is fabricated and subjected to a series of preliminary laboratory tests. The experimental results show that the proposed TMPD can reduce effectively the acceleration response of the main structure while converting a part of the dissipated energy into electric power with the proposed concept.
