Description

Technical Field

[0001] The present invention relates to the field of building structure design and earthquake resistance technology, and more particularly to an earthquake-resistant toughness structure with a regular shape. Background Art

[0002] Traditional building structures often have insufficient seismic performance under earthquakes due to factors such as irregular structural shapes and unreasonable arrangement of vertical tension and compression supports. They are prone to serious damage such as collapse, causing huge casualties and economic losses. For example, some complex building structures are prone to stress concentration during earthquakes, causing local structures to bear excessive loads and be destroyed first, which in turn causes the instability and collapse of the entire structure. In addition, there are many problems in the design of vertical supports, such as unbalanced vertical force and limit functions, which cannot effectively limit the vertical deformation of the structure under earthquakes, resulting in insufficient seismic toughness of the building under extreme conditions.

[0003] In recent years, with the development of structural mechanics and earthquake-resistant technology, some new building structures, such as frame structures, frame-shear structures, silo structures, etc., have begun to be applied in earthquake-resistant design. However, in practical applications, these structural systems still have some problems. For example, frame structures are prone to damage to beam-column joints under earthquakes, the coordination between the shear wall and the frame of the frame-shear structure is not ideal, and the silo structure may have a weak link in the connection between the cylinder and the foundation due to the unreasonable design of the vertical support. The existence of these problems makes it difficult for the seismic performance of existing building structures in earthquakes to meet the increasingly stringent seismic requirements.

[0004] In addition, there is relatively little research on the stiffness distribution and limit function of vertical supports in existing structural designs, and the arrangement of supports often lacks scientific optimization design, resulting in uneven vertical force on the structure under earthquake action, and prone to excessive local deformation, which may lead to overall structural damage. At the same time, the existing technology for implementing the limit function of vertical supports is relatively simple, lacks an effective energy dissipation mechanism, and cannot effectively protect the structure from damage under earthquake action.

[0005] Therefore, how to achieve effective shock absorption and energy dissipation of regular-shaped building structures under earthquakes without significantly increasing construction costs, and ensure structural safety and stability, is a difficult problem that needs to be solved urgently in the current architectural design field. An innovative design that can improve the seismic toughness of the structure, ensure uniform force on the vertical support system, and have a vertical limit function is needed to fundamentally improve the seismic performance of the structure. Summary of the invention

[0006] In view of this, the present invention provides a seismic toughness structure with a regular shape, aiming to solve the above technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A seismic toughness structure with a regular shape comprises: an upper structure, a vertical tension and compression support and a lower foundation structure, wherein the upper structure is connected to the lower foundation structure via the vertical tension and compression support, and the overall structure composed of the upper structure, the vertical tension and compression support and the lower foundation structure is regularly and symmetrically arranged at three viewing angles; there are multiple vertical tension and compression supports, and the stiffness values ​​of the multiple vertical tension and compression supports are symmetrically arranged around the lower foundation structure.

[0009] Through the above technical scheme, the present invention requires that the building structure has a regular and symmetrical shape. This design helps to evenly propagate seismic waves inside the structure, reduce stress concentration, and avoid structural instability caused by local uneven force, thereby improving the overall stability and seismic resistance of the structure.

[0010] Preferably, in the above-mentioned seismic toughness structure with regular shape, a plurality of horizontal displacement limiting supports are connected between the upper structure and the lower foundation structure, and the plurality of horizontal displacement limiting supports are symmetrically arranged around the lower foundation structure.

[0011] Preferably, in the above-mentioned seismic toughness structure with regular shape, the horizontal displacement limiting support allows its vertical displacement and limits its horizontal displacement.

[0012] Preferably, in the above-mentioned seismic toughness structure with regular shape, the horizontal displacement limiting support has the function of vertical tension and compression energy absorption.

[0013] Preferably, in the above-mentioned seismic toughness structure with regular shape, the upper structure is connected to the plurality of vertical tension and compression supports through a connecting beam at the bottom of the structure.

[0014] Preferably, in the above-mentioned seismic toughness structure with regular shape, the lower foundation structure includes a pile foundation pedestal connected to a plurality of the vertical tension and compression supports, the pile foundation pedestals are connected by pile foundation pedestal connecting beams, and piles are fixed at the bottom of the pile foundation pedestal.

[0015] Preferably, in the above-mentioned seismic toughness structure with regular shape, the vertical tension and compression supports include but are not limited to spring supports, rubber supports and hydraulic supports.

[0016] Preferably, in the above-mentioned seismic toughness structure with regular shape, the vertical tension and compression support realizes the vertical limiting function through a limiting block, a limiting pin or a limiting sensor.

[0017] Preferably, in the above-mentioned seismic toughness structure with regular shape, it also includes an elastic buffer layer arranged inside the vertical tension and compression support.

[0018] Preferably, in the above-mentioned seismic toughness structure with regular shape, the superstructure includes but is not limited to a frame structure, a frame-shear structure and a silo structure.

[0019] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a seismic toughness structure with a regular shape. The regular and symmetrical shape design and symmetrically arranged vertical tension and compression supports of the present invention enable the structure to produce a relatively uniform stress distribution and deformation mode under the action of an earthquake, avoiding the occurrence of stress concentration and uneven deformation, thereby significantly improving the seismic performance of the structure. The uniform stiffness distribution of the vertical tension and compression supports enables the structure to bear vertical loads more stably during an earthquake, and the overall seismic resistance is greatly improved.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See attached Figure 1 To Attachment Figure 2 The embodiment of the present invention discloses a seismic toughness structure with a regular shape, which is characterized in that it includes: an upper structure 1, a vertical tension and compression support 2 and a lower foundation structure 3, the upper structure 1 is connected to the lower foundation structure 3 through the vertical tension and compression support 2, and the overall structure composed of the upper structure 1, the vertical tension and compression support 2 and the lower foundation structure 3 is regularly and symmetrically arranged at three viewing angles; the number of the vertical tension and compression supports 2 is multiple, and the stiffness values ​​of the multiple vertical tension and compression supports 2 are symmetrically arranged around the lower foundation structure 3.

[0033] Each vertical tension and compression support 2 not only bears the transmission of vertical loads, but also has a vertical limiting function, that is, it ensures that the vertical deformation does not exceed the set limit through the limiting device.

[0034] In this embodiment, if Figure 2 As shown, K1-K4 are all vertical tension and compression supports 2, where K1, K2, K3, and K4 represent the stiffness values ​​of the vertical tension and compression supports in the four main directions (such as front and back, left and right, or diagonal directions) at the bottom of the structure, to ensure the uniformity of the force of the structure under earthquake action. Ensure that K1 = K2, K3 = K4.

[0035] The working principle of this embodiment is:

[0036] This embodiment adopts a regular and symmetrical layout. The regular structure has a uniform stress state, which can effectively reduce the uneven deformation and stress concentration caused by the irregular structure. The symmetrical layout further improves the seismic performance of the structure and avoids instability or uneven vibration under the action of seismic loads.

[0037] The arrangement of vertical tension and compression supports at the bottom of the structure is an important innovation of the present invention. Traditional structures usually use vertical supports to transfer vertical loads, but the present invention further requires that these supports be arranged symmetrically in terms of vertical stiffness. Specifically, Figure 2 As shown, supports K1 and K2, supports K3 and K4 have the same vertical tension and compression stiffness, that is, K1 = K2, K3 = K4. This design not only ensures the uniformity of the structure under vertical load, but also improves the overall seismic toughness of the structure and prevents displacement or dislocation caused by asymmetric support stiffness.

[0038] The vertical tension and compression stiffness K1, K2, K3, and K4 of the vertical tension and compression supports can be adjusted to adapt to different earthquake intensities and structural design requirements and improve the seismic adaptability of the structure.

[0039] The vertical tension and compression bearings not only play a supporting role, but also limit the vertical deformation by setting up limit devices. The design of the limit device should set the deformation limit value according to the actual needs of the structure. During the design, the maximum limit of vertical deformation can be set according to the seismic requirements and the bearing capacity of the material. When the bearing is subjected to vertical force, if the deformation exceeds the limit, the limit device will take effect in time to prevent the structure from destructive deformation, thereby ensuring the stability and safety of the structure.

[0040] When implementing the present invention, suitable materials and construction methods can be selected according to specific circumstances. Commonly used materials include reinforced concrete, steel, prestressed steel bars, etc., which can provide sufficient strength and rigidity. In terms of construction, existing frame, frame-shear, silo and other structural forms can be adopted. These forms have good earthquake resistance and can effectively realize the vertical rigidity and limit function of the vertical support through reasonable design.

[0041] During the design process, all loads on the structure should be considered, especially earthquake effects. In earthquake analysis, the seismic capacity of the structure is calculated and evaluated by using appropriate seismic wave modes and response spectrum analysis methods. Special attention should be paid to the effects of vertical loads, horizontal loads, and possible changes in seismic wave frequency and amplitude on the structure. On this basis, the stiffness design of the vertical supports and the setting of the limit devices are optimized to ensure that the structure can remain stable and avoid excessive deformation under earthquake action.

[0042] According to the design drawings, vertical tension and compression bearings are installed symmetrically at the bottom of the structure to ensure that the positions of the bearings are accurate and the stiffness is consistent. During the installation process, the bearings need to be precisely calibrated to ensure that they can evenly distribute the load when subjected to force.

[0043] After installation, static and dynamic loading tests are performed to verify whether the stiffness and limit function of the support meet the design requirements. During the test, the deformation of the support, stress distribution, and the working status of the limit device should be recorded to further optimize and adjust the structure.

[0044] In order to further optimize the above technical solution, a plurality of horizontal displacement limiting supports 4 are further connected between the upper structure 1 and the lower foundation structure 3 , and the plurality of horizontal displacement limiting supports 4 are symmetrically arranged around the lower foundation structure 3 .

[0045] In order to further optimize the above technical solution, the horizontal displacement limiting support 4 allows its vertical displacement and limits its horizontal displacement.

[0046] In order to further optimize the above technical solution, the horizontal displacement limiting support 4 has the vertical tension and compression energy dissipation function.

[0047] It can be seen that the horizontal displacement limiting support 4 only allows the support to displace vertically, and can have both vertical tensile and compressive energy dissipation functions, or it can only serve as a horizontal displacement limiting device, without providing a vertical bearing function and without being subjected to stress under vertical loads.

[0048] In order to further optimize the above technical solution, the upper structure 1 is connected to a plurality of vertical tension and compression supports 2 via a structural bottom connecting beam 5 .

[0049] In order to further optimize the above technical solution, the lower foundation structure 3 includes a pile foundation pedestal 31 connected to multiple vertical tension and compression supports 2. The pile foundation pedestals 31 are connected by pile foundation connecting beams 32, and piles 33 are fixed at the bottom of the pile foundation pedestals 31.

[0050] In order to further optimize the above technical solution, the vertical tension and compression support 2 includes but is not limited to a spring support, a rubber support and a hydraulic support.

[0051] In order to further optimize the above technical solution, the vertical tension and compression support 2 realizes the vertical limiting function through a limiting block, a limiting pin or a limiting sensor.

[0052] In order to further optimize the above technical solution, an elastic buffer layer is also included in the vertical tension and compression support 2. When the vertical deformation of the support approaches the limit value, the elastic buffer layer can absorb part of the energy and further reduce the vertical deformation of the support.

[0053] In order to further optimize the above technical solution, the superstructure 1 includes but is not limited to a frame structure, a frame-shear structure and a silo structure, and the structure is regular and symmetrical. The design of the superstructure 1 should ensure that it can effectively disperse and transfer loads under earthquake action.

[0054] In this embodiment, the upper structure 1 is composed of an upper structure tube wall 11, an upper structure column 12 and an upper structure beam 13. The upper structure tube wall 11 is located in the middle, the upper structure column 12 is located at the edge, and the upper structure beam 13 connects the upper structure tube wall 11 and the upper structure column 12.

[0055] In other embodiments, in order to adjust the seismic response of the structure, prevent the structure from being overly deformed when subjected to force, or reduce stress concentration in the middle part, Figure 2 A vertical tension and compression support 2 can also be set at the K5 position in the middle. The stiffness of the middle support K5 is different from the stiffness of the surrounding supports K1, K2, K3, and K4. The stiffness of K5 is usually larger, depending on the design requirements. The middle support is located in the center of the structure and bears different distributions from vertical loads, horizontal loads or seismic loads.

[0056] This embodiment has the characteristics of regular and symmetrical structural shape, symmetrical arrangement of the vertical tension and compression stiffness of the vertical tension and compression supports 2 around the bottom of the structure, vertical limiting function of the vertical tension and compression supports, and is suitable for various types of regular-shaped building structures. These characteristics work together to significantly improve the overall seismic performance of the structure.

[0057] The structure provided in this embodiment has the following advantages:

[0058] 1. The regular, symmetrical shape design and symmetrically arranged vertical tension and compression supports enable the structure to produce a relatively uniform stress distribution and deformation mode under earthquake action, avoiding stress concentration and uneven deformation, thereby significantly improving the seismic performance of the structure. The uniform stiffness distribution of the vertical tension and compression supports enables the structure to bear vertical loads more stably during earthquakes, and the overall seismic resistance is greatly improved.

[0059] 2. The vertical limit function of the vertical tension and compression bearing effectively limits the vertical deformation of the structure under earthquake action, prevents the structure from excessive vertical displacement, and enhances the stability of the structure. Even under strong earthquake action, the structure can maintain a certain stability and avoid serious damage such as collapse caused by excessive vertical deformation.

[0060] 3. It is not only applicable to common frame structures, but also widely applicable to various types of regular-shaped building structures or special structures such as frame-shear structures and silo structures. By adopting the technical solution of the present invention in different types of structures, it can meet the seismic requirements of different building structures and has wide applicability and practicality.

[0061] 4. The design takes into account the operability of construction. The arrangement of vertical tension and compression supports and the realization of limiting functions are carried out through standardized components and processes, which helps to simplify the construction process, reduce construction costs, and improve construction efficiency, thereby bringing significant economic benefits.

[0062] 5. Through optimized design, the earthquake resistance and toughness of buildings in earthquakes are significantly improved, and the losses caused by earthquake disasters are reduced. In high-rise buildings and special buildings, it can especially improve the overall safety of buildings, ensure the safety of people's lives and property, and has important social significance.

[0063] Through the above design, this embodiment can effectively improve the seismic toughness of the structure under the action of external forces such as earthquakes, ensure that the building can maintain sufficient stability and safety when encountering vibrations, and minimize the damage caused by earthquakes.
