Problems solved by technology

However, in the current research process, although the structure size is much smaller than that of the Bragg scattering structure, in practice, a larger structure size is still used to control low-frequency surface waves, which is not only uneconomical, but also has low application

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings: the low-frequency shock-absorbing supergrain plate structure unit cell includes a steel core (1) with a cylindrical through hole and a rubber layer (2).

[0032] First, the steel block is arranged at the core position, and the steel block is a cube with a side length of 0.8m. Through technological means, two cylindrical through holes are respectively opened on the four vertical sides of the steel block.

[0033] Afterwards, a rubber layer (1) is coated on the outer side of the perforated steel core (1). The inside of the rubber layer (2) is in close contact with the outer surface of the steel core (1). The four vertical surfaces of the rubber layer (2) are opened along the side hole positions of the steel core (1).

[0034] The body centers of the steel core (1) with side holes and the rubber layer (2) coincide with each other.

[0035] see figure 2 and image 3 ,...

Abstract

The invention discloses a low-frequency shock-absorbing seismic super-glume structure. The seismic super-glume structure is formed by extending seismic super-glume structure unit cells in the horizontal plane in two mutually perpendicular directions and is designed on the periphery of a building foundation, wherein each seismic super-glume structure unit cell comprises a steel core with side holes and a rubber layer with side holes; the steel cores and the rubber layers are all cubes, and cylindrical through holes are formed in the four perpendicular faces; the low-frequency shock-absorbing seismic super-glume structure is buried under the ground surface of the building foundation and arranged in the circumferential direction of a building; the low-frequency shock-absorbing seismic super-glume structure is made of steel and rubber; and the low-frequency shock-absorbing seismic super-glume structure is formed by extending the seismic super-glume structure unit cells in the horizontal plane in the two mutually perpendicular directions, and each seismic super-glume structure unit cell is mainly formed by wrapping steel with the side holes with the rubber layer with the side holes. According to the low-frequency shock-absorbing seismic super-glume structure, the band gap width and position are adjusted by changing the diameters of the side holes and geometric and material parameters of all the components, and thus one or more buildings in different areas and at different heights are protected.

Description

technical field [0001] The invention relates to a low-frequency shock-absorbing seismic supergrain structure, which is a new structure with good control and attenuation effects on seismic surface waves. Background technique [0002] According to statistics, the economic losses caused by earthquakes in the world account for 60% of the economic losses caused by all disasters. The damage caused by earthquakes to humans is mainly due to the collapse of buildings, which seriously affects the safety of human life and property. Seismic waves are divided into body waves and surface waves. Among them, low-frequency seismic surface waves have the greatest impact on building safety due to their characteristics of low frequency, high amplitude, difficult attenuation, and long-distance propagation. The frequency range of low-frequency seismic surface waves that has the greatest impact on buildings is in the range of 0.1-20Hz, and the corresponding wavelength of seismic surface waves in...
