Description

Technical Field

[0001] This invention relates to the field of seismic wave isolation technology in civil engineering, specifically to an embedded vertical NPR surface wave isolation resonator and a seismic isolation barrier. Background Technology

[0002] Earthquakes and their secondary disasters are extremely destructive, with building collapse being one of the most significant causes of casualties and substantial property damage. Therefore, improving the seismic performance of buildings and effectively reducing these hazards has become an urgent task and a popular research topic. The seismic performance of a structure depends on its mass, strength, deformation capacity, and damping. To ensure the safety of the main structure, traditional vibration reduction and energy dissipation methods direct the energy input from a seismic event to specific energy dissipation devices, effectively increasing the structure's damping. However, these energy dissipation units are often integrated with the main structure, easily leading to excessive lateral deformation and residual deformation of the main structure. Furthermore, excessive residual deformation can cause repair costs to exceed reconstruction costs, resulting in considerable economic losses. Summary of the Invention

[0003] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the prior art, and to provide an embedded vertical NPR surface wave isolation resonator and vibration isolation barrier.

[0004] To achieve the above objectives, according to a first aspect of the present invention, an embedded vertical NPR surface wave isolation resonator is provided, comprising a top concrete cap, a first NPR frame layer, a steel column, a second NPR frame layer, a bottom concrete cap, and a concrete enclosure box. The upper end face of the first NPR frame layer is connected to the lower end face of the top concrete cap by carbon steel flange bolts, and the lower end face of the first NPR frame layer is connected to the upper end face of the steel column by carbon steel flange bolts; the upper end face of the second NPR frame layer is connected to the lower end face of the steel column by carbon steel flange bolts, and the lower end face of the second NPR frame layer is connected to the bottom concrete cap by carbon steel flange bolts; the concrete enclosure box has a hollow center, and the upper end face of the concrete enclosure box is connected to the lower end face of the top concrete cap, and the lower end face of the concrete enclosure box is connected to the upper end face of the bottom concrete cap.

[0005] A further embodiment is that both the first NPR frame layer and the second NPR frame layer are spliced ​​together from a solid structure with a negative Poisson's ratio effect made of rubber material; the top concrete cap, the bottom concrete cap and the concrete encapsulation box are made of reinforced concrete, and the steel columns are made of carbon steel.

[0006] A further embodiment is that both the first and second NPR framework layers include a first structure, a second structure, a third structure, and a fourth structure; the first, second, third, and fourth structures are vertically mirror-symmetrical negative Poisson's ratio solid structures; each of the first, second, third, and fourth structures includes two first rubber blocks, two carbon steel flanges, two mortise and tenon rubber blocks, and two second rubber blocks; the carbon steel flanges are used for bolting the first, second, third, and fourth structures to the top concrete cap, bottom concrete cap, and steel columns; the mortise and tenon rubber blocks are all right quadrangular prisms with square bases; the two first rubber blocks and the two second rubber blocks are arranged in a circular array along the center line of the mortise and tenon rubber blocks. The mortise and tenon rubber blocks are symmetrically arranged vertically. The lower ends of the four sides of the upper mortise and tenon rubber block are respectively mortised and tenoned to the upper ends of the sides of two first rubber blocks and two second rubber blocks. The upper ends of the four sides of the lower mortise and tenon rubber block are respectively mortised and tenoned to the lower ends of the sides of two first rubber blocks and two second rubber blocks. The two first rubber blocks and two second rubber blocks have the same structure and are all "C" shaped. The upper mortise and tenon rubber block has a first annular groove at its upper end, and the lower mortise and tenon rubber block also has a first annular groove symmetrically formed at its lower end. Two carbon steel flanges are respectively snapped into the first annular grooves of the two mortise and tenon rubber blocks. The first structure, the second structure, the third structure, and the fourth structure are connected to each other in sequence through the second rubber blocks.

[0007] A further embodiment includes rubber fixing rings, with a second annular groove in the middle of each of the two second rubber blocks. The two ends of the rubber fixing rings are respectively engaged in the second annular grooves of the adjacent negative Poisson's ratio solid structures, so that the first structure, the second structure, the third structure and the fourth structure are fixedly connected together. Each second rubber block has three second annular grooves at equal intervals along the height direction in its middle.

[0008] A further option is that both the top and bottom concrete caps are designed as cuboid structures, and the structural dimensions of the top and bottom concrete caps are identical.

[0009] A further option is to design the steel column as a solid cuboid structure.

[0010] A further option is to configure the concrete encapsulation box as a hollow cuboid structure with wall thickness.

[0011] A further embodiment is that the cross-sections of the top concrete cap, the bottom concrete cap, and the concrete encapsulation box are all squares of equal size.

[0012] A further option is that the wall thickness of the concrete enclosure box is 0.06 mm.

[0013] According to a second invention of the present invention, an embedded vertical NPR surface wave isolation barrier is provided, which is formed by periodically arranging any of the embedded vertical NPR surface wave isolation resonators described above.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention proposes an embedded vertical NPR surface wave isolation resonator by using a first NPR frame layer and a second NPR frame layer made of rubber material with excellent damping and energy absorption characteristics, combined with the characteristics of local resonance type seismic metamaterial to achieve low frequency seismic isolation. The resonator consists of a top concrete cap, a first NPR frame layer, a steel column, a second NPR frame layer, a bottom concrete cap, and a concrete encapsulation box. In addition, combined with the local resonance characteristics of the resonator itself, it can cope with the ultra-low frequency band gap generated by ultra-low frequency seismic waves.

[0015] (2) The first NPR frame layer and the second NPR frame layer in this invention are both made of rubber material and spliced ​​together with negative Poisson's ratio solid structure with negative Poisson's ratio effect and embedded between the concrete cap and steel column of the resonator. When the resonator interacts with Rayleigh waves that propagate in an elliptical manner, the solid structure of the NPR frame layer can provide a "stretching effect" (negative expansion effect of material) to the inside of the resonator when the resonator is subjected to stress vibration deformation, and at the same time play the role of energy absorption and energy dissipation of the negative Poisson's ratio structure. Therefore, this can improve the overall structural strength of the resonator, enhance the overall durability of the resonator structure, and at the same time combine the characteristics of the resonator's own local resonance, so as to cope with the ultra-low frequency band gap generated by ultra-low frequency seismic waves.

[0016] (3) This invention provides an embedded vertical NPR surface wave isolation barrier, which is composed of a periodic array of embedded vertical NPR surface wave isolation resonators. It can be deployed around various large-scale basic buildings and urban clusters for seismic isolation. The application method is simple. It utilizes the resonance characteristics of the structure itself to interact with Rayleigh waves in seismic waves to generate a low-frequency bandgap. When the surface wave located in the frequency bandgap range propagates to the embedded vertical NPR surface wave isolation resonator buried on the ground, the surface wave will be converted into a downward propagating body wave, thereby effectively suppressing the low-frequency resonance phenomenon of the building and achieving the purpose of attenuating low-frequency seismic waves.

[0017] (4) By leveraging the differences in the three materials used to construct the components and based on the inherent properties of these materials, this invention offers advantages over traditional seismic isolation barriers. Traditional barriers cannot isolate ultra-low frequency seismic waves, while this invention achieves an ultra-low frequency ultra-wide bandgap, providing excellent isolation for low-frequency seismic waves. Furthermore, this invention fully utilizes the significant differences in parameters between rubber, concrete, and steel to achieve flexible and adjustable phonon crystal bandgap.

[0031] Example 1

[0032] As attached Figure 1-3 As shown, this embodiment provides an embedded vertical NPR surface wave isolation resonator, comprising six parts: a top concrete cap 1, a first NPR frame layer 2, a second NPR frame layer 4, a steel column 3, a bottom concrete cap 5, and a concrete encapsulation box 6. First, the bottom concrete cap 5 is installed. Then, the second NPR frame layer 4 is connected to the bottom concrete cap 5. Next, the steel column 3 is placed on the second NPR frame layer 4, and then the first NPR frame layer 2 is connected directly above it. Then, the top concrete cap 1 is connected. Finally, the concrete encapsulation box 6 is used to encapsulate the above internal structure and form a whole with the top concrete cap 1 and the bottom concrete cap 5.

[0033] The top concrete cap 1 and the bottom concrete cap 5 have the same dimensions, both with a length:width:height ratio of 1.7m:1.7m:0.35m. The first NPR frame layer 2 and the second NPR frame layer 4 have the same dimensions, with a length:width:height ratio of 0.8m:0.8m:0.4m. The solid rectangular steel column 3 has dimensions of length:width:height of 0.9m:0.9m:1.1m. The outer wall of the concrete enclosure box 6 has a rectangular structure with dimensions of length:width:height of 1.7m:1.7m:1.9m and a wall thickness of 0.05m.

[0034] Specifically, the rubber used in the first NPR frame layer 2 and the second NPR frame layer 4 has a density of 1050 kg / m3, a Young's modulus E = 2.0 × 106 Pa, and a Poisson's ratio μ = 0.3; the concrete used in the bottom concrete cap 5, the top concrete cap 1, and the concrete enclosure box 6 has a density ρ = 2500 kg / m3, a Young's modulus E = 4 × 1010 Pa, and a Poisson's ratio μ = 0.2; and the steel used in the steel columns has a density ρ = 7800 kg / m3, a Young's modulus E = 2.1 × 1011 Pa, and a Poisson's ratio μ = 0.3.

[0035] Example 2

[0036] Refer to the instruction manual appendix Figure 1-8 This embodiment proposes an embedded vertical NPR surface wave isolation resonator, which is periodically arranged in the foundation to form a seismic isolation barrier. See [link to documentation]. Figure 7 The resonator with negative Poisson's ratio structure includes a top concrete cap 1, a first NPR frame layer 2, a steel column 3, a second NPR frame layer 4, a bottom concrete cap 5, and a concrete encapsulation box 6. The embedded NPR surface wave isolation barrier is formed by periodically arranging embedded vertical NPR surface wave isolation resonators to form an earthquake metamaterial isolation barrier. The top concrete caps 1 of adjacent isolation resonators are connected to each other, and the bottom concrete caps 5 of adjacent isolation resonators are connected to each other.

[0037] Embedded vertical NPR surface wave isolating resonator seismic metamaterial. When Rayleigh waves in seismic waves pass through this metamaterial, a low-frequency bandgap is generated due to local resonance. Rayleigh waves located in the bandgap are converted into downward propagating body waves when passing through the metamaterial, thus achieving a seismic isolation effect.

[0038] Please see Figures 4-6Both the first NPR frame layer 2 and the second NPR frame layer 4 are made of rubber, and their length:width:height ratio is 0.8:0.8:0.4. Both the first NPR frame layer 2 and the second NPR frame layer 4 include a first structure I, a second structure II, a third structure III, and a fourth structure IV. The first structure I, the second structure II, the third structure III, and the fourth structure IV are vertically mirror-symmetrical negative Poisson's ratio solid structures. The first structure I, the second structure II, the third structure III, and the fourth structure IV of the first NPR frame layer 2 are distributed in a ring array between the top concrete cap 1 and the steel column 3, and the first structure I, the second structure II, the third structure III, and the fourth structure IV of the second NPR frame layer 4 are distributed in a ring array between the steel column 3 and the bottom concrete cap 5. It can be understood that the ring array of the first structure I, the second structure II, the third structure III, and the fourth structure IV embedded between the concrete cap and the steel column 3 helps to improve the overall durability and strength of the resonator.Structures I, II, III, and IV each include two first rubber blocks A, two carbon steel flanges B, two mortise and tenon rubber blocks C, two second rubber blocks D, and a rubber fixing ring E. The carbon steel flanges B are used for bolting connections between Structures I, II, III, and IV and the top concrete cap 1, bottom concrete cap 5, and steel column 3. The mortise and tenon rubber blocks C are all right-angled prisms with a square base. The two first rubber blocks A and the two second rubber blocks D are positioned along the mortise and tenon rubber blocks... The centerline of the C-shaped rubber blocks is arranged in a circular array, with two mortise and tenon rubber blocks C arranged symmetrically one above the other. The lower ends of the four sides of the upper mortise and tenon rubber block C are respectively mortised and tenoned to the upper ends of the sides of the two first rubber blocks A and the two second rubber blocks D. The upper ends of the four sides of the lower mortise and tenon rubber block C are respectively mortised and tenoned to the lower ends of the sides of the two first rubber blocks A and the two second rubber blocks D. The two first rubber blocks A and the two second rubber blocks D have the same structure and are both "C"-shaped. It can be understood that the two mortise and tenon rubber blocks C are spaced apart from each other, respectively... The steel column 3 and the concrete cap are connected to the resonator via flange bolts on the carbon steel flange B. When Rayleigh waves in the bandgap frequency range are transmitted to the resonator and interact with it, the resonator reaches its own resonant frequency and vibrates internally. The vibration causes the internal force to increase and generate energy. At the same time, the energy generated by the internal force is absorbed and dissipated by the negative Poisson's ratio structure of the first NPR frame layer 2 and the second NPR frame layer 4. The first rubber block A and the two second rubber blocks D are both "C" shaped, which is to better mortise and tenon the mortise and tenon rubber block C and form an integral whole with it. Through a "stretching effect" (the negative expansion effect of the material), the internal force of the resonator generated by the internal resonance deformation is effectively dissipated. The upper end of the upper mortise and tenon rubber block C has a first annular groove, and the lower end of the lower mortise and tenon rubber block C also has a first annular groove symmetrically opened. The two carbon steel flanges B are respectively snapped into the first annular grooves of the two mortise and tenon rubber blocks C. The first structure I, the second structure II, the third structure III and the fourth structure IV are connected to each other in sequence through the second rubber blocks D.

[0039] Specifically, each of the two adjacent negative Poisson's ratio solid structures has a second annular groove in its middle. The rubber fixing ring E is engaged at both ends within the second annular grooves of the adjacent negative Poisson's ratio solid structures, thus fixing the first structure I, second structure II, third structure III, and fourth structure IV together to form a stable negative Poisson's ratio frame structure. Each second rubber block D has three second annular grooves spaced equidistantly along its height in its middle.

[0040] Specifically, steel column 3 is a solid cuboid structure with a length:width:height ratio of 0.9m:0.9m:1.1m.

[0041] Specifically, both the top concrete cap 1 and the bottom concrete cap 5 are cuboid structures with dimensions of length:width:height = 1.7m:1.7m:0.35m.

[0042] Specifically, the upper surface of the first NPR frame layer 2 is connected to the lower surface of the top concrete cap 1, and the lower surface of the first NPR frame layer 2 is connected to the upper surface of the steel column 3, forming a unified structure; the upper surface of the second NPR frame layer 4 is connected to the lower surface of the steel column 3, and the lower surface of the second NPR frame layer 4 is connected to the upper surface of the bottom concrete cap 5, forming a unified structure, so that the structure of the first NPR frame layer 2, the steel column 3, and the second NPR frame layer 4 after installation is integrated, without any obvious protrusions or depressions.

[0043] Specifically, the installation method of the embedded NPR surface wave resonator provided in this embodiment includes the following steps: First, install the bottom concrete cap 5; second, connect the second NPR frame layer 4 to the bottom concrete cap 5; then, set the steel column 3 on the second NPR frame layer 4; then connect the first NPR frame layer 2 directly above it; then connect the top concrete cap 1; finally, use a concrete encapsulation box 6 to encapsulate the above internal structure and form a whole with the top concrete cap 1 and the bottom concrete cap 5.

[0044] Reference Figure 8 The left half describes a numerical simulation of an embedded vertical NPR surface wave isolator resonator. The dispersion curves are calculated by scanning the Brillouin zone using the aforementioned material parameters and adding Floquet periodic boundary conditions and setting parameters. (Refer to...) Figure 8 The right half shows the transmission spectrum curves obtained from frequency domain analysis of 30 NPR surface wave resonators. Figure 8 The shaded area formed by the structure in the numerical simulation represents the band gap opened by the structure designed in this application. The band gap ranges from 0.86 to 11.35 Hz, while the frequency range of seismic waves is typically 0.1 to 20 Hz. Therefore, this structure can effectively attenuate low-frequency seismic waves. Multiple resonators designed in this invention are periodically distributed on the ground surface, thus forming an embedded NPR surface wave isolation barrier for attenuating seismic waves, as described in this invention. Figure 8 This demonstrates that the present invention is very effective in attenuating low-frequency seismic waves.

[0045] Working principle of this invention: Figure 8As shown, when an earthquake occurs, the Rayleigh wave generated by the earthquake propagates to an embedded vertical NPR surface wave metamaterial seismic isolation barrier used to attenuate seismic waves. Due to the 0.86-11.35Hz band gap generated by its resonance, when the frequency of the seismic wave is within this band gap range, it will be prohibited from propagating, thereby converting the surface wave generated by the earthquake into a body wave, so that the seismic wave cannot cause damage to existing buildings and structures, and finally achieving the effect of attenuating low-frequency seismic waves.
