Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure design and earthquake resistance technology, and more specifically to a regular-shaped earthquake-resistant and resilient structure. Background Technology
[0002] Traditional building structures, under earthquake loads, often suffer from insufficient seismic performance due to irregular shapes and improper vertical tension / compression bearing arrangements, making them prone to collapse and other severe damage, resulting in significant casualties and economic losses. For example, complex building structures are prone to stress concentration during earthquakes, causing localized structures to bear excessive loads and fail first, subsequently leading to overall structural instability and collapse. Furthermore, the design of vertical supports also presents numerous problems, such as an imbalance between vertical force distribution and restraint functions, failing to effectively limit vertical deformation under earthquake loads, resulting in insufficient seismic toughness in extreme conditions.
[0003] In recent years, with the development of structural mechanics and earthquake-resistant technology, some new building structural forms, such as frame structures, frame-shear wall structures, and silo structures, have begun to be applied in seismic design. However, in practical applications, these structural systems still have some problems. For example, frame structures are prone to beam-column joint failure under earthquake loads; the coordination between the shear walls and the frame in frame-shear wall structures is not ideal; and silo structures may have weak links at the connection between the silo and the foundation due to unreasonable vertical support design. These problems mean that the seismic performance of existing building structures still struggles to meet increasingly stringent earthquake resistance requirements.
[0004] Furthermore, existing structural designs have relatively few studies on the stiffness distribution and restraint function of vertical supports. The arrangement of supports often lacks scientific optimization, leading to uneven vertical stress on the structure under seismic loading, which can easily result in excessive local deformation and overall structural failure. At the same time, existing technologies for implementing the restraint function of vertical supports are relatively simple and lack effective energy dissipation mechanisms, failing to effectively protect the structure from damage under seismic loading.
[0005] Therefore, how to achieve effective seismic damping and energy dissipation under earthquakes for regularly shaped building structures without significantly increasing construction costs, and ensure structural safety and stability, is a pressing problem in the field of architectural design. An innovative design is needed that can improve the seismic toughness of the structure, ensure uniform stress distribution in the vertical support system, and also provide vertical restraint functions, in order to fundamentally enhance the seismic performance of the structure. Utility Model Content
[0006] In view of this, the present invention provides a seismically resistant and resilient structure with a regular shape, aiming to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A seismically resilient structure with a regular shape includes: a superstructure, vertical tension-compression supports, and a substructure. The superstructure is connected to the substructure via the vertical tension-compression supports. The overall structure consisting of the superstructure, the vertical tension-compression supports, and the substructure is arranged regularly and symmetrically from three viewing angles. There are multiple vertical tension-compression supports, and the stiffness values of the multiple vertical tension-compression supports are symmetrically arranged around the substructure.
[0009] Through the above technical solution, this utility model requires the building structure to be regular and symmetrical. This design helps the seismic waves to propagate evenly inside the structure, reduces stress concentration, avoids structural instability caused by uneven local stress, and thus improves the overall stability and seismic resistance of the structure.
[0010] Preferably, in the above-mentioned seismic-resistant and resilient structure with a 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-resistant and resilient structure with a regular shape, the horizontal displacement limiting support allows vertical displacement and restricts horizontal displacement.
[0012] Preferably, in the above-mentioned seismic-resistant and resilient structure with a regular shape, the horizontal displacement limiting support has a vertical tensile and compressive energy dissipation function.
[0013] Preferably, in the above-mentioned seismically resilient structure with a regular shape, the superstructure is connected to multiple vertical tension and compression supports through a bottom connecting beam.
[0014] Preferably, in the above-mentioned seismic-resistant and resilient structure with a regular shape, the lower foundation structure includes a pile cap connected to a plurality of vertical tension and compression supports, the pile caps are connected by pile cap connecting beams, and piles are fixed at the bottom of the pile cap.
[0015] Preferably, in the above-mentioned seismic-resistant and resilient structure with a regular shape, the vertical tension and compression bearings include, but are not limited to, spring bearings, rubber bearings, and hydraulic bearings.

[0018] Preferably, in the above-mentioned seismically resilient structure with a regular shape, the superstructure includes, but is not limited to, a frame structure, a frame-shear structure, and a silo structure.
[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a seismically resilient structure with a regular shape.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] See appendix Figure 1 To be continued Figure 2 This utility model discloses a seismically resistant and resilient structure with a regular shape, characterized in that it includes: an upper structure 1, vertical tension and compression supports 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 supports 2. The overall structure composed of the upper structure 1, the vertical tension and compression supports 2, and the lower foundation structure 3 is arranged in a regular and symmetrical manner from three viewing angles. There are multiple vertical tension and compression supports 2, 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 / compression support 2 not only bears the transmission of vertical loads, but also has a vertical limiting function, that is, the vertical deformation is guaranteed not to exceed the set limit value through the limiting device.
[0034] In this embodiment, as Figure 2 As shown, K1-K4 are all vertical tension-compression supports 2, where K1, K2, K3, and K4 represent the stiffness values of the vertical tension-compression supports in the four main directions (front-back, left-right, or diagonal) at the bottom of the structure, respectively, to ensure the uniformity of stress on the structure under seismic loading. Ensure that K1 = K2 and K3 = K4.
[0035] The working principle of this embodiment is as follows:
[0036] This embodiment adopts a regular and symmetrical layout. A regular structure has a uniform stress state, effectively reducing uneven deformation and stress concentration caused by irregular structures. The symmetrical layout further improves the structure's seismic performance, preventing instability or uneven vibration under seismic loads.
[0037] The arrangement of vertical tension / compression supports at the bottom of the structure is a significant innovation of this invention. Traditional structures typically use vertical supports to transfer vertical loads, while this invention further requires these supports to be symmetrically arranged in terms of vertical stiffness. Specifically, as... Figure 2 As shown, supports K1 and K2, and supports K3 and K4 have the same vertical tensile and compressive stiffness, i.e., K1 = K2, K3 = K4. This design not only ensures the uniformity of the structure under vertical loads, but also improves the overall seismic toughness of the structure and prevents displacement or misalignment caused by asymmetry in support stiffness.
[0038] The vertical tension and compression stiffness K1, K2, K3, and K4 of the vertical tension and compression bearings can all be adjusted to adapt to different seismic intensities and structural design requirements, thereby improving the seismic adaptability of the structure.
[0039] Vertical tension / compression supports not only provide structural support but also limit vertical deformation through limiting devices. The design of these limiting devices should be based on the actual structural requirements, setting deformation limits. During the design phase, the maximum limit for vertical deformation can be set according to seismic requirements and the load-bearing capacity of the materials. When the support is under vertical load, if the deformation exceeds the limit, the limiting device will activate promptly to prevent destructive deformation of the structure, thereby ensuring its stability and safety.
[0040] When implementing this utility model, appropriate materials and construction methods can be selected according to specific circumstances. Commonly used materials include reinforced concrete, steel, and prestressed steel bars, which can provide sufficient strength and stiffness. In terms of construction, existing frame, frame-shear wall, and silo structures can be adopted. These structures have good seismic resistance and, through reasonable design, can effectively realize the vertical stiffness and limiting function of the vertical supports.
[0041] During the design process, all loads on the structure, especially seismic forces, should be considered. In seismic analysis, the structure's seismic resistance should be calculated and evaluated using appropriate seismic wave modes and response spectrum analysis methods. Particular attention should be paid to the effects of vertical loads, horizontal loads, and potential variations in seismic wave frequency and amplitude on the structure. Based on this, the stiffness design of vertical supports and the setting of limiting devices should be optimized to ensure the structure remains stable under seismic loading and avoids excessive deformation.
[0042] According to the design drawings, vertical tension and compression supports are installed symmetrically at the bottom of the structure to ensure that the position of each support is accurate and the stiffness is consistent. During installation, the supports need to be precisely calibrated to ensure that they can distribute the load evenly when under stress.
[0043] After installation, static and dynamic loading tests should be conducted to verify whether the stiffness and limiting function of the support meet the design requirements. During the testing process, the deformation of the support, stress distribution, and the working status of the limiting device should be recorded to facilitate further optimization and adjustment of the structure.
[0044] To further optimize the above technical solution, multiple horizontal displacement limiting supports 4 are connected between the upper structure 1 and the lower foundation structure 3, and the multiple horizontal displacement limiting supports 4 are symmetrically arranged around the lower foundation structure 3.
[0045] To further optimize the above technical solution, the horizontal displacement limiting support 4 allows vertical displacement while restricting horizontal displacement.
[0046] To further optimize the above technical solution, the horizontal displacement limiting support 4 has a vertical tension and compression energy dissipation function.
[0047] Therefore, it can be seen that the horizontal displacement limiting support 4 only allows the vertical displacement of the support, and can also serve as a vertical tension and compression energy dissipation function, or it can only serve as a horizontal displacement limiting device, without providing a vertical bearing function, and it is not subjected to force under vertical load.
[0048] To further optimize the above technical solution, the superstructure 1 is connected to multiple vertical tension and compression supports 2 through the bottom connecting beam 5.
[0049] To further optimize the above technical solution, the lower foundation structure 3 includes a pile cap 31 connected to multiple vertical tension and compression supports 2. The pile caps 31 are connected by pile cap connecting beams 32, and piles 33 are fixed at the bottom of the pile caps 31.
[0050] To further optimize the above technical solution, the vertical tension / compression support 2 includes, but is not limited to, spring supports, rubber supports, and hydraulic supports.
[0051] To further optimize the above technical solution, the vertical tension / compression support 2 achieves vertical limiting function through a limit block, limit pin, or limit sensor.
[0052] To further optimize the above technical solution, an elastic buffer layer is also included inside the vertical tension / compression support 2. When the vertical deformation of the support approaches the limit, the elastic buffer layer can absorb some energy, further reducing the vertical deformation of the support.
[0053] To further optimize the above technical solutions, the superstructure 1 includes, but is not limited to, frame structures, frame-shear wall structures, and silo structures, with a regular and symmetrical shape. The design of the superstructure 1 should ensure that it can effectively distribute and transfer loads under seismic loading.
[0054] In this embodiment, the upper structure 1 consists of an upper structure cylindrical wall 11, an upper structure column 12, and an upper structure beam 13. The upper structure cylindrical 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 cylindrical wall 11 and the upper structure column 12.
[0055] In other implementations, to adjust the seismic response of the structure, prevent excessive deformation under stress, or reduce stress concentration in the middle section, Figure 2 A vertical tension / compression support 2 can also be installed at position K5 in the structure. The stiffness of the central support K5 differs from that of the surrounding supports K1, K2, K3, and K4. The stiffness of K5 is usually greater, depending on the design requirements. The central support is located in the center of the structure and bears different distributions of vertical loads, horizontal loads, or seismic loads.
[0056] This embodiment features a regular and symmetrical structural shape, with the vertical tension and compression stiffness of the vertical tension and compression supports 2 arranged symmetrically around the bottom of the structure, and the vertical tension and compression supports have a vertical limiting function. It is suitable for various types of regular building structures. These features 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 and symmetrical shape design and symmetrically arranged vertical tension-compression supports enable the structure to generate a more uniform stress distribution and deformation mode under seismic loading, avoiding stress concentration and uneven deformation, thereby significantly improving the seismic performance of the structure. The uniform stiffness distribution of the vertical tension-compression supports allows the structure to withstand vertical loads more stably during earthquakes, greatly improving the overall seismic resistance.
[0059] 2. The vertical restraint function of the vertical tension-compression supports effectively limits the vertical deformation of the structure under seismic loading, preventing excessive vertical displacement and enhancing structural stability. Even under strong seismic loading, the structure can maintain a certain degree of stability, avoiding serious damage such as collapse due to excessive vertical deformation.
[0060] 3. Not only is it suitable for common frame structures, but it can also be widely applied to various types of regular-shaped building structures or special structures such as frame-shear wall structures and silo structures. By adopting the technical solution of this utility model in different types of structures, the seismic resistance requirements of different building structures can be met, demonstrating its wide applicability and practicality.
[0061] 4. The design takes into account the operability of construction. The arrangement and limiting function of the vertical tension and compression supports are achieved 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 resilience of buildings are significantly improved, reducing losses caused by earthquake disasters. This is particularly important for high-rise and special buildings, enhancing overall building safety and ensuring the safety of life and property, thus having significant social implications.
[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, ensuring that the building can maintain sufficient stability and safety when encountering vibrations, and minimizing the damage caused by earthquakes.
