heal.abstract	We show that it is possible to successfully apply the concept of nonlinear targeted energy transfer (TET) to seismic protection of structures. We consider a three-story shear frame structure under seismic excitation, modeled as a three degree-of freedom (DOF) system. We consider four historic earthquakes as seismic excitation. The seismic mitigation is achieved by connecting a vibro-impact attachment (termed a vibro-impact NES - VI NES) applied to the top floor of the structure. In order to assess the robustness of the VI NES, the NES parameters were optimized for a specific seismic excitation (Kobe), and then tested against the three other seismic excitations to demonstrate effectiveness of the NES for these cases as well.
