Large-scale experimental evaluation and numerical simulation of a system of nonlinear energy sinks for seismic mitigation

Seismic mitigation of a large system coupled to SSVI NES was studied.

“Moreover, the seismic mitigation of a large system coupled to SSVI NES was also studied in [109].”

In these large-scale structures, the SSVI NES dissipated significant energy during the highly energetic initial phase through consecutive inelastic impacts and redistribution and dissipation of a portion of energy at high frequency modes.

“In these large-scale structures, the SSVI NES was able to dissipate significant amount of energy during the highly energetic initial phase of excitation through consecutive inelastic impacts and the redistribution and dissipation of portion of the energy at high frequency modes.”

Vibro-impact NESs have shown a unique performance in experiments where the highest energy motion in the initial stage was efficiently reduced and therefore the structure was protected.

“As demonstrated in [109,110], the VI NESs have shown a unique performance in the experiments where the highest energy motion in the initial stage was efficiently reduced and therefore the structure was protected.”

After first successful realization of SSVI NES in a 2-story linear primary structure, a series of publications followed on a large-scale 9-story structure coupled with two SSVI NES in the eighth and ninth floors.

“After the first successful realization of SSVI NES in [107] in which a 2-story linear primary structure was considered, series of publications in which a large-scale 9-story structure coupled with two SSVI NES in the eighth and ninth floors followed [106,109,110].”

Most research works related to SSVI NESs contained experimental evaluations.

“One important observation deduced from the review conducted is that most research works related to SSVI NESs [107, 109, 110] contained experimental evaluations.”

The largest test bed for TET testing is the 11-ton 9-story steel frame structure investigated in [106,109,110] for seismic and shock mitigations using SSVI NESs and Type I NESs.

“To the author's knowledge, the largest test bed for TET testing is the 11-ton 9-story steel frame structure investigated in [106,109,110] for seismic and shock mitigations using SSVI NESs and Type I NESs.”
