Embedded vertical NPR surface wave isolation resonator and seismic isolation barrier
The invention discloses an embedded vertical NPR surface wave isolation resonator and an isolation barrier, and belongs to the technical field of earthquake protection. The NPR surface wave isolation resonator comprises a top concrete cap, a first NPR frame layer, a steel column, a second NPR frame layer, a bottom concrete cap and a concrete packaging box. The first NPR frame layer and the second NPR frame layer are formed by splicing negative Poisson's ratio solid structures which are made of rubber materials and have the negative Poisson's ratio effect and are embedded between the concrete caps and the steel column. The vibration isolation barrier has the advantages that the overall durability and strength of the resonator structure can not be ensured when a traditional seismic metamaterial vibration isolation barrier cannot realize an ultra-wide and ultra-low frequency band gap and the whole resonator is stressed, vibrates and deforms at the same time; the energy absorption and energy consumption effect of the negative Poisson's ratio solid structure and the local resonance characteristic of the resonator are exerted, and then the ultra-low frequency band gap generated by ultra-low frequency seismic waves can be dealt with.
本发明公开了一种嵌入式竖向NPR面波隔离谐振器及隔离屏障，属于地震防护技术领域。NPR面波隔离谐振器包括顶部混凝土帽、第一NPR框架层、钢柱、第二NPR框架层、底部混凝土帽和混凝土封装箱，第一NPR框架层和第二NPR框架层均由橡胶材质构成的具有负泊松比效应的负泊松比实体结构拼接而成并嵌入在混凝土帽与钢柱之间。本发明的优点为传统地震超材料隔震屏障不能在实现超宽超低频带隙的同时还能保持谐振器整体受力振动变形时，保证谐振器结构整体的耐久性与强度，并且在隔离地震波时，发挥负泊松比实体结构的吸能耗能作用与谐振器自身局域共振的特性，进而可应对超低频地震波产生的超低频带隙。
