Steel trunk-branch bionic ultralow-frequency seismic metasurface
The invention relates to the field of building seismic resistance, in particular to a steel trunk-branch bionic ultralow-frequency seismic metasurface. Comprising tree-shaped resonators, a protected object is enclosed in the center by a plurality of resonators, each tree-shaped resonator comprises a steel trunk and steel branches, the steel trunk is vertically fixed on the surface of the earth surface, the steel branches comprise a plurality of steps of steel branches, the first-step steel branch is fixedly connected with the top of the steel trunk, and the second-step steel branch is fixedly connected with the top of the steel trunk. The tops of the steel branches are fixedly connected with the bottoms of the lower-step steel branches in sequence. The array is fixed on the ground around a protected object, and when surface waves reach the array, surface wave components such as Rayleigh waves are converted into deep body waves through fluctuation mode conversion, so that structural seismic resistance is realized.
本发明涉及建筑抗震领域，特别是一种钢制树干‑树枝仿生超低频地震超表面。包括树形谐振器，数个谐振器将被保护物封闭的围合在中心，树形谐振器包括钢制树干和钢制树枝，钢制树干垂直固定在地表表面上，钢制树枝包括数阶钢制树枝，其中钢制一阶树枝与钢制树干的顶部固定连接，钢制树枝的顶部依次与其下阶钢制树枝的底部固定连接。将其固定在被保护物周围的地面上，在面波到达阵列时，通过波动模式转换将瑞丽波等面波分量转换为深层体波，实现结构抗震。
