Description

(I) Technical Field:

[0001] This invention relates to fields such as construction, manufacturing, and transportation that are affected by the lateral shear damage caused by seismic waves. (II) Background Technology:

[0002] With the advancement of science and technology, and through a renewed analysis and study of various historical earthquake disasters, the understanding of traditional earthquake-resistant concepts has gradually shifted. Through relentless exploration and innovation of various earthquake-resistant and vibration-damping systems, earthquake-resistant design has moved beyond simply reinforcing the building structure. Based on the structural dynamics, diverse vibration-damping concepts and methods are used to mitigate the lateral impact of seismic waves on the structure. This has led to the development of technologies such as base isolation systems, suspension vibration reduction systems, damper energy absorption and dissipation systems, mass resonance damping systems (TMD), and active control vibration reduction, which have gradually been applied in engineering practice and achieved good results.

[0003] However, due to differing understandings of the mechanisms of earthquake vibrations and the concepts of earthquake resistance and vibration reduction, various earthquake-resistant, vibration-damping, and vibration-isolation systems and earthquake-resistant designs all have serious shortcomings. These are mainly reflected in the following aspects: Firstly, existing building earthquake-resistant designs are constrained by the level of earthquake-resistant technology and national economic capacity. Even the mandatory standard, the "Earthquake Resistance Code," is still based on the design principle of "no damage in minor earthquakes, repairable in moderate earthquakes, and no collapse in major earthquakes." This is limited by the difficulty in accurately quantifying and comprehensively covering the intensity, frequency, regional distribution, and probability statistics of earthquakes occurring in the historical period of the area. Its regional earthquake-resistant design standard (only including earthquakes of intensity 6-9) results in an inherently insufficient ability of constructed structures to withstand damage when facing high-intensity earthquakes or cross-regional earthquakes. In particular, the lack of design for earthquakes exceeding intensity 9 has become a root cause of catastrophic human destruction caused by mega-earthquakes with long latency periods and low probability of occurrence. Secondly, the reinforcement, buffering, damping, and vibration isolation methods employed are all inherently "anti-vibration," forcing the building structure to absorb a large amount of vibration energy during an earthquake, leading to wave penetration, structural deformation, and resonance, thus endangering the structural safety. Thirdly, existing basic building materials generally cannot provide sufficient flexibility for the deformation of earthquake-resistant structures and vibration isolation devices. This means that after absorbing a large amount of vibration energy, the earthquake-resistant structure cannot maintain its stiffness to keep pace with the vibration waves, given its enormous mass and inertia. First, resonance with the same amplitude, frequency, and direction avoids the lateral shear of the vibration wave, but it cannot meet the requirement that the structure fully extends and deforms to release vibration energy due to insufficient lateral stiffness of the material itself under vibration, which is allowed by the elastic modulus of the material. As a result, the structure and vibration isolation device suffer shear damage. Second, the inertial state of the existing building structure is forced to change when the vibration wave acts laterally. While generating huge lateral resistance, it will also generate asynchronous, different frequency, and different amplitude resonance with the vibration wave. It will transmit the reverse vibration to the supporting foundation, forming a disturbance to the foundation soil structure, reducing or losing the bearing capacity of the foundation, and causing the building structure to sink, become unstable, or even overturn.

[0004] In view of the shortcomings of existing earthquake resistance, vibration reduction, buffering, and vibration isolation technologies, this paper discloses an inertial lateral shear vibration damping technology that uses drag reduction and "resistance" elimination to block the lateral action of seismic waves and transmit them to the building structure. This technology eliminates the lateral shear damage caused by seismic waves by releasing the lateral restraint between the main building structure and its supporting foundation, and by utilizing the inertia of the building structure's own mass to allow for free and wide relative staggered displacement with the supporting foundation during an earthquake. (See attached diagram) Figure 1 To promote the advancement of earthquake-resistant technology and foster harmonious coexistence between human society and the natural environment through more scientific, simple, safe, and easily implemented methods. (III) Summary of the Invention:

[0005] The inertial yaw damping technology of this invention lies in: using a yaw balance support device (referring to a device that eliminates the lateral shear of vibration waves by means of yaw deformation and balance support, hereinafter referred to as: yaw balance support device (see attached figure: Figure 1 , Figure 4 , Figure 5 Mark 3 and Figure 2 Sub-figures 2-1-1, 2-2-1, 2-3-1, 2-4-1, 2-5-1, 2-6-1, 2-7-1, 2-8-1, and 2-9-1) separate the vibration wave conduction bearing body (referring to: solid natural structures (e.g., the earth, mountains, caves, etc.) connected to the vibration source body and capable of directly conducting the lateral action of the vibration wave and thus generating particle displacement with vibration) and solid constructed structures (e.g., foundations, bases, pile caps, platforms, carriers, etc.) bearing the upper vertical load and thus generating particle displacement with the lateral action of the vibration wave). Hereinafter, they are all referred to as: vibration wave conduction bearing bodies (see attached figure). Figure 1 , Figure 4 , Figure 5 The term "shock-bearing structure" (as indicated in Figure 1) refers to a structure that requires protection under the lateral action of a seismic wave and possesses mass inertia characteristics (e.g., buildings, bridges, equipment, devices, frames, etc.). Hereinafter, both are simply referred to as "shock-bearing structures" (see attached diagram). Figure 1 , Figure 4 , Figure 5 (See note 2)) Utilizing the inherent mass inertia of the vibration-bearing structure to resist deformation (see attached diagram: Figure 2 (Note 11) and the transverse force of the vibration wave transmitted by the vibration wave carrier (see attached diagram:) Figure 2 (Note 12) Reverse action drives the yaw balance support device to yaw with low impedance (see attached diagram:) Figure 2 (See Figures 2-1-2, 2-2-2, 2-3-2, 2-4-2, 2-5-2, 2-6-2, 2-7-2, 2-8-2, and 2-9-2). This releases the traditional lateral constraint between the wave-conducting carrier and the vibration-supporting structure, preventing the wave from being transmitted through the interaction of the lateral resistance of the vibration-supporting structure. This allows the wave-conducting carrier and the vibration-supporting structure to move freely, omnidirectionally, with full amplitude and low impedance, in staggered displacements (see attached diagram). Figure 2 (Note 10) This ensures that the vibration-bearing structure no longer bears the lateral shear of the vibration wave and maintains its original inertial state. It also ensures that the vibration wave transmission bearing body no longer bears the anti-vibration reaction force, thus disturbing and weakening the foundation bearing capacity, thereby achieving the purpose of eliminating the harm of the lateral action of the vibration wave.

[0006] The technical problem to be solved:

[0007] 1. The core problem that this invention aims to solve in existing earthquake resistance and vibration reduction technologies is that: it is impossible to avoid the reverse resistance that will always be generated when the structure is subjected to the lateral action of the vibration wave, which causes the vibration wave to penetrate into the structure, resulting in changes in the internal forces, deformation and resonance, and damage. Conversely, the vibration reaction force of the structure during the earthquake is transmitted, which disturbs the original structure of the foundation soil layer supporting the vibration wave transmission and reduces the bearing capacity.

[0008] 2. The present invention aims to solve the safety problems of existing earthquake resistance, vibration reduction and isolation technologies, as well as inertial yaw damping technology in earthquake resistance by addressing the required safety boundaries of reliability, stability, vibration tolerance, low impedance, and controllable yaw displacement.

[0009] 3. The problem that this invention aims to solve in existing vibration isolation and inertial yaw damping technologies is that, while using yaw buffering to weaken and eliminate the lateral shear of vibration waves, it still needs to consider providing basic tensile, bending, and torsional resistance as needed.

[0010] 4. The problem that this invention aims to solve, which is a problem that cannot be ignored in existing earthquake-resistant technologies, is to avoid the physical and chemical defects of building materials and vibration-damping materials in earthquake-resistant applications.

[0011] 5. The present invention aims to address the common problems of existing earthquake-resistant technologies, namely: the complexity of the technology, high investment costs, difficulty in implementation, insufficient earthquake-resistant safety and reliability, difficulty in maintenance, and inability to quantify and standardize for mass industrial production and widespread application.

[0012] Technical solution:

[0013] The overall technical solution of this invention lies in completely abandoning the traditional earthquake-resistant technology approach and using a brand-new inertial vibration damping model to transform traditional buildings into vibration damping integrated bodies that are statically and dynamically separated yet interconnected and interdependent. This is an inertial lateral vibration damping fusion body composed of a wave-conducting bearing body, a lateral balancing support device (composed of multiple lateral balancing support devices arranged in a triangular or matrix pattern on the horizontal plane), and a vibration-bearing structure. By releasing the lateral constraints between them, the wave-conducting bearing body is allowed to move freely with the vibration during an earthquake without obstruction; the vibration-bearing structure maintains its original lateral motion state unaffected by vibration due to its own mass inertia; through the reaction action of the wave-conducting body and the vibration-bearing structure, the lateral balancing support device is driven to laterally swing freely, in full amplitude, in all directions, and with low impedance in the plane tangential to the support axis, eliminating the interaction between the lateral shear force of the wave and the inertial lateral resistance reaction force of the vibration-bearing structure. This prevents the upward transmission of the lateral force of the wave from endangering the vibration-bearing structure due to deformation and damage, and the downward transmission of the inertial resistance reaction force of the vibration-bearing structure from disturbing the foundation soil layer and weakening its support capacity. The peak value of the actual lateral displacement of surface protons in a quantifiable destructive earthquake of high intensity is used as the basis for the safe vibration-tolerant design of the inertial yaw vibration damping technology. The yaw balance support device is given a wide swing amplitude to encompass the peak value of surface proton displacement in high-intensity earthquake sites that have not been sheared and damaged by seismic waves, except for landslides and ground fissures. This achieves a wide and reliable safe vibration-tolerant capability for the inertial yaw vibration damping technology.

[0014] The core of the technical solution of this invention lies in the following: the lateral balancing support device is composed of a support base, a support top seat, and a lateral balancing support mechanism with a single or multiple rotating cores (multiple rotating cores specifically refer to a mode in which three or more rotating cores are arranged in a triangular or matrix-like horizontal plane between a pair of support bases and support top seats to form an independent fulcrum balancing support). Through the counter-movement of the support base and support top seat when subjected to vibration, the rotating core of the lateral balancing support mechanism is driven to roll and reciprocate, achieving a "hinge" rotation and fully staggered displacement of the top and bottom supports (see attached diagram). Figure 2 (10) Avoid the lateral shear of the vibration wave and achieve the vibration damping mode of the lateral balance support device freely reciprocating laterally with the vibration.

[0015] The core of the technical solution of this invention lies in: the rotating core of the pendulum support mechanism rotates with the vibration, and the support spacing (hereinafter referred to as the support distance, see attached figure) is adjusted. Figure 2 (Notes 7 and 8) Increments in static and dynamic states (see attached diagram) Figure 2 Mark 9, and make 9>0), so that the centroid of the longitudinal section of the static and dynamic support of the rotating core is always limited to the undulating lateral movement within the allowable range of the relative support width, creating a corresponding static and dynamic balance support "V valley" for the free rolling load support of the rotating core, and creating a non-statically indeterminate environment for the vibration-bearing structure to be supported in a statically and dynamically suitable, balanced, stable and safe manner.

[0016] The core of the technical solution of this invention lies in: ensuring that the static offset of the pivot of the pendulum support mechanism is less than the dynamic offset, and ensuring that the radius of the corresponding support surface of the pendulum support mechanism is greater than the static and dynamic offsets of the pivot, thereby eliminating the risk of instability of the lateral pendulum balance support device under static and dynamic load-bearing oscillation. The difference between the static and dynamic offsets (see attached figure) Figure 2 The value of (9) is used to adjust the relative support displacement bearing force (see attached diagram). Figure 2 (13, 14) Rotational torque generated by the interlacing action of the off-center bearing shafts (see attached diagram): Figure 2 (Note 15) and additional adjustable static offset (see attached diagram:) Figure 2 The value of (marked 7) balances the yaw resistance and yaw sensitivity, enabling the pendulum support mechanism to automatically rotate and swing back to its original position after the lateral vibration disappears (see attached diagram). Figure 2 The ability to reduce label 9 to 0 and label 7 to 8.

[0017] The core of the technical solution of this invention lies in: optimizing the configuration of the pendulum support mechanism (see attached figure). Figure 2 Sub-graphs 2-3-2, 2-7-2, 2-8-2, and 2-9-2. Figure 3 (See Figures 3-7, 3-8, 3-9, 3-10, 3-11, and 3-12) for details on obtaining a higher capacitive swing amplitude for the pendulum support mechanism under the same support cross-sectional width (see attached figures). Figure 2 (Note 10) This allows for the containment of surface mass displacement values ​​during large earthquake peaks with a smaller support cross-section. Furthermore, by increasing the load area of ​​the sliding bearing of the pendulum support mechanism's core, the high static and dynamic load-bearing requirements of the pendulum support mechanism are met.

[0018] The core of the technical solution of this invention lies in: matching the sliding degree of freedom of the pendulum support curved surface of the pendulum support mechanism with the guiding configuration (see attached figure). Figure 2 Sub-graphs 2-7-3 and 2-8-3, Figure 3 (See Figures 3-7, 3-8, 3-11, and 3-12), and the limit of the permissible boundary of the pendulum (see attached figure). Figure 2 The setting (16) enables the lateral balance support device to meet the requirements of axial bearing and eliminating lateral shear while retaining other mechanical characteristics (including torsional, tensile, and bending resistance), and to prevent the excessive rotation of the rotating core when the excessive amplitude occurs, thus preventing the lateral balance support device from overswinging and becoming unstable.

[0019] The core of the technical solution of this invention lies in: by greatly simplifying the configuration of the swing support mechanism, a simple structure is achieved (see attached figure). Figure 2 Sub-diagram 2-9-1, Figure 3(Figure 3-9) and single compressive bearing capacity, by expanding the selection of materials such as natural stone, artificial stone, ceramics, concrete, and metal that can meet the requirements of high strength, low creep and durability, industrial processing and production can meet the needs of ordinary residential buildings in vast villages and towns to resist major earthquakes, and significantly reduce production and use costs and maintenance and promotion difficulties.

[0020] Structural features of the yaw balance support device:

[0021] 1. The lateral balancing support device and its pendulum support mechanism: The pendulum support surface radius is not less than the offset of the rolling and sliding pivot, providing a dynamic increment for the reciprocating pendulum offset of the rolling and sliding pivot (see attached diagram). Figure 2 The value of 9 is not less than 0.

[0022] 2. The slewing support mechanism of the lateral balance support device: its rolling support surface can be a flat surface, a curved cylindrical surface formed by stretching a straight or curved line segment, or a flat surface and a spherical curved surface formed by rotation, etc.

[0023] 3. The swing support mechanism of the lateral balance support device: its ability to select the number of swing core combinations and the configuration of single swing cores or stacked swing cores as needed.

[0024] 4. The swing support mechanism of the lateral balance support device: its swing resistance limit can be added as needed.

[0025] 5. The swing support mechanism of the lateral balance support device: It has an interlocking groove guide and limit structure that can be added as needed for the relatively curved cylindrical support surface that fits and slides.

[0026] (iv) Beneficial effects:

[0027] 1. The beneficial effects of this invention are as follows: Using innovative inertial yaw vibration damping technology, this invention provides a simple, efficient, safe, and reliable method. By using the peak proton displacement value of the surface in non-destructive landslide and ground fissure earthquake sites as the basis for seismic fortification, it significantly improves the seismic fortification vibration damping level, completely changing the current situation of earthquake-resistant buildings being "undamaged in small earthquakes, repairable in moderate earthquakes, and not collapsing in large earthquakes." Based on existing global large-scale earthquake data observation records and corresponding earthquake intensity tables (China Earthquake Intensity Table GB / T17742-2008 or Modified McCully Intensity Table), combined with the geological structural characteristics of the seismic field, the maximum possible displacement of the peak surface mass point (PGD) at an earthquake intensity of 10 (usually triggered by a large earthquake of magnitude M7.5 or higher) is estimated. (For soil and rock sites: dominant period T = 0.5–1s, estimated PGD...) h =12.7CM, actual observation range =10~15CM; ordinary thick soil site: dominant period T =1.0~1.5s, estimated PGD h=19.1CM, actual possible range =15~25CM; soft soil / basin site: dominant period T =1.5~2.5s, estimated PGD h =31.8CM, actual observation range =25~50CM) take the maximum value of 50CM as the reference; take the maximum possible displacement of the surface mass point at the peak earthquake when the intensity is 11 (usually caused by a super-massive earthquake with a magnitude of M≥8.5) (bedrock / hilly site: dominant period T=1.0~1.5s, estimated PGD h =40~80CM, actual observation range =30~120CM) Taking 120CM as a reference example, and comparing it with the hyperboloid sliding single core in the inertial yaw damping technology (see attached figure: Figure 2 2-3-2, 2-9-2 Figure 3 (3-9) and the four-curved surface sliding composite core (see attached diagram:) Figure 2 2-7-2, 3-8-2 Figure 3 The safe swing amplitude of the lateral balance support device with configurations (3-7, 3-8, 3-10, 3-11, 3-12) can achieve a maximum safe lateral swing displacement of 80 cm on one side of the static support shaft when the cross-sectional width of the support is 1 M. This clearly covers the peak surface proton displacement reference value for all types of earthquake-affected sites without shear failure at seismic intensity 10 and below. For rock / hilly sites without shear failure at seismic intensity 11 and for particularly important seismic scenarios, in addition to widening the lateral swing support mechanism to over 1.5 M, the required safe over-compression vibration capacity can be met by arranging lateral swing support devices in multiple layers (two or more) of the transverse plane of the vibrating structure, using a layered and superimposed seismic damping method. This significantly reduces the complexity and cost of seismic structural design by ensuring that buildings are not damaged in major earthquakes, providing a simple and reliable solution for preventing earthquake damage to structures in safe sites for all non-destructive earthquakes. By reducing seismic resistance to lateral vibration damping and quantifying the reliability of lateral vibration tolerance of the lateral support device, the maximum displacement of surface particles in the non-shear-damaged foundation of the seismic zone is included, eliminating the risk of life and property from major earthquakes and creating a long-term safe living environment for humans in the seismic zone under non-landslide and subsidence devastating major earthquake conditions.

[0028] 2. The beneficial effects of the present invention are: it greatly simplifies the complexity of the design of new earthquake-resistant structures and reduces the construction cost of excessive seismic reinforcement of structures and the high maintenance costs for long-term use and after earthquakes.

[0029] 3. The beneficial effects of this invention are as follows: it uses simple, easy-to-replicate, and easily expandable technology, and the materials are readily available, which is conducive to achieving quantitative standardization and large-scale industrial production and popularization. It provides a new way to accelerate the upgrading of a large number of existing low-seismic-resistance buildings through reinforcement and replacement, speeds up the national reconstruction process of buildings in earthquake-prone areas, and significantly reduces the huge reinvestment costs of the country and the people in the repair and reconstruction of fixed assets after earthquakes.

[0094] This involves constructing or upgrading a transverse vibration damping fusion structure (see attached diagram). Figure 1 , Figure 4 , Figure 5 In this method, the yaw balance support device (see attached figure: label 3) in the inertial yaw vibration damping technology is used to separate the wave-conducting carrier (see attached figure: label 1) and the vibration-bearing structure (see attached figure: label 2). By utilizing the low-impedance free yaw function of the yaw balance support device, the lateral restraint of the wave-conducting carrier is removed from all vibration-bearing structures with mass inertia characteristics. This makes them non-statically indeterminate inertial laterally free-balancing bodies stably supported by the yaw balance support device, no longer subject to the lateral shear of the wave, thus achieving the vibration damping objective described in the inertial yaw vibration damping technology scheme.
