Combined seismic metamaterial suitable for layered soil
The invention discloses a combined seismic metamaterial suitable for layered soil, which comprises a plurality of unit cells arranged according to a square lattice period, and each unit cell comprises a cylindrical concrete column and an annular five-layer composite material wrapping the periphery of the lower half section of concrete; the annular five-layer composite material is flush with the bottom of the concrete stand column and is as high as the part, embedded underground, of the concrete stand column; the annular five-layer composite material comprises steel, rubber, polystyrene, rubber and polystyrene from outside to inside; the upper half section of the concrete stand column is arranged on the ground, the lower half section is embedded into the first soil layer, and the second soil layer and the third soil layer are sequentially arranged below the first soil layer. According to the combined seismic metamaterial, the multi-material composite annular structure is adopted to form a quasi-vibrator system, the energy absorption and vibration reduction characteristics of the multi-material composite annular structure are fully utilized, part of the metamaterial is on the ground, part of the metamaterial is embedded into the ground, and a wider low-frequency band gap is provided within the frequency range of 20 Hz or below.
本发明公开了一种适用于分层土壤的组合型地震超材料，包括按照正方晶格周期排列的多个单胞，所述单胞包括圆柱形混凝土立柱和包裹在混凝土下半段外围的环状五层复合材料；所述环状五层复合材料与混凝土立柱底部平齐，高度与混凝土立柱嵌入地下部分高度相同；所述环状五层复合材料由外到内为钢，橡胶，聚苯乙烯，橡胶，聚苯乙烯；混凝土立柱上半段在地面，下半段嵌入第一土壤层，在第一土壤层下面依次为第二土壤层和第三土壤层。本发明的组合型地震超材料，采用多材料复合的环状结构组成类振子系统，充分利用了多材料复合的环状结构的吸能和减振特性，并且部分在地表，部分嵌入地下，在20Hz以下的频率范围内提供更宽的低频带隙。
