As a novel dynamic vibration absorber, the nonlinear energy sink has been studied for mitigating structural and mechanical vibration through the last decade. This paper presents a series of large-scale experimental evaluations and numerical simulations on a system of nonlinear energy sink (NES) devices for mitigating seismic structural responses. Two distinct types of NES devices were installed in the top two floors of a large-scale model building structure. In the device system, four Type I NESs employing smooth essentially nonlinear restoring forces were used in conjunction with two single-sided vibro-impact (SSVI) NESs employing non-smooth impact nonlinearities. These NES devices utilize …
