Negative Poisson's ratio-local resonance seismic isolation structure and resonator

The invention discloses a negative Poisson's ratio-local resonance seismic isolation structure and a resonator, and belongs to the technical field of seismic wave seismic isolation. The negative Poisson's ratio-local resonance seismic isolation structure comprises a top concrete cap, a first negative Poisson's ratio cushion layer, a second negative Poisson's ratio cushion layer, a steel column, a bottom concrete cap and a concrete packaging box; the first negative Poisson's ratio cushion layer and the second negative Poisson's ratio cushion layer are members made of negative Poisson's ratio foam materials. The ultra-low-frequency and ultra-wide-frequency band gap seismic isolation barrier has the advantages that a traditional seismic isolation barrier cannot achieve isolation of ultra-low-frequency seismic waves, the ultra-low-frequency and ultra-wide-frequency band gap can be obtained, and the effect of isolating the low-frequency seismic waves is good. In addition, the negative Poisson's ratio foam, concret
