Eccentric resonance seismic metasurface
The invention discloses an eccentric resonance seismic metasurface. The surface wave defense array which is small in size and easy to construct can prevent surface waves from being spread to densely populated urban areas, and the earthquake safety of urban building structures is greatly improved. The device comprises a plurality of eccentric resonators, and the eccentric resonators are annularly arranged with a protected building as the center. The eccentric resonator comprises an eccentric steel column which is vertically fixed on the ground surface; the eccentric steel column comprises a vertical section and an eccentric section, the vertical section is perpendicularly fixed to the ground, and the eccentric section is fixed to the top of the vertical section. A mass block is fixed at the top of the eccentric section; the central axis of the vertical section is a certain distance away from the gravity center of the mass block. The eccentric seismic metasurface is separated from a protected building and does not participate in vertical stress of the protected building, so that the protected building and the seismic metasurface are not prone to damage.
本发明公开了一种偏心谐振地震超表面。实现小尺寸易建造的表面波防御阵列能够阻止表面波的传播到人口密集的城市区域，极大地提高城市建筑结构的地震安全性。本发明包括多个偏心谐振器，偏心谐振器以被保护建筑为中心，呈环形布置；偏心谐振器包括偏心钢柱，偏心钢柱垂直固定在地表；偏心钢柱包括竖直段和偏心段，竖直段垂直固定于地面，偏心段固定于竖直段顶部；偏心段顶部固定有质量块；竖直段的中心轴线与质量块的重心相距一定距离。本发明的偏心地震超表面与被保护建筑相互分离，不参与被保护建筑的竖向受力，使得被保护建筑和本抗震超表面都不易发生损坏。
