Description

Technical Field

[0001] This utility model relates to the technical field of earthquake-resistant structural systems, and more specifically to an integral rocking self-resetting frame-support structure. Background Technology

[0002] With the rapid urbanization in China, the height and complexity of buildings are constantly increasing. In earthquake-prone areas, buildings must not only withstand daily static loads but also possess excellent seismic resistance to cope with potential extreme natural disasters. Therefore, the seismic performance and stability of structures have become increasingly important. While traditional frame structures can meet the load-bearing requirements to a certain extent, they often exhibit significant deformation under extreme loads, potentially leading to structural damage and collapse. Therefore, improving the seismic resistance of building structures has become a crucial issue that urgently needs to be addressed in the field of engineering technology.

[0003] In recent years, self-resetting structure technology has gradually attracted attention. In previous designs, frame structures typically used rigid connections to fix the superstructure to the foundation. While this design performs well under static loads, it is prone to bending, shearing, and flexural-shear deformation under dynamic loads such as earthquakes, leading to permanent deformation and structural damage. Self-resetting structures, through their own design, can quickly return to their original state after earthquakes or other loads, thus avoiding the permanent deformation that occurs in traditional structures after an earthquake. This technology not only improves the durability of the structure but also reduces maintenance and reinforcement costs.

[0004] However, existing self-resetting frame structures still have some shortcomings, such as limited self-resetting ability, construction complexity, and high requirements for material properties.

[0005] Therefore, developing a structure that can improve its overall seismic performance and self-resetting ability while ensuring structural safety has important practical significance and application value. Utility Model Content

[0006] In view of this, the present invention provides an integral swing self-resetting frame-support structure, which aims to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An integral rocking self-resetting frame-support structure includes:

[0009] Foundation cap;

[0010] The frame has its bottom ends of the frame columns in the middle connected to the top surface of the foundation platform via rotating hinge supports, and the bottom ends of the frame columns on both sides connected to the top surface of the foundation platform via vertical tension and compression supports. When the frame rotates around the rotating hinge supports, the vertical tension and compression supports provide an elastic force in the vertical direction.

[0011] Through the above technical solution, this utility model provides an integral swaying self-resetting frame-support structure. Compared with the prior art, it effectively absorbs and disperses seismic energy through the overall swaying of the frame, the deformation and rotation of the bottom vertical tension and compression supports and hinged supports, thereby reducing the impact of vibration on the structure. This structure has strong stability and a strong self-resetting ability, avoiding the permanent deformation that may occur in traditional frame structures after an earthquake, reducing maintenance and reinforcement costs, and protecting structural safety.

[0012] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the top surface of the frame is also fixed with a horizontal limiting device for the support. The number of the horizontal limiting devices for the support is the same as the number of the vertical tension and compression supports, and they are located one-to-one on the outside of the vertical tension and compression supports. The horizontal limiting devices for the support restrict the horizontal displacement of the vertical tension and compression supports.

[0013] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the horizontal limiting device of the support is a rectangular cylinder arranged around the vertical tension and compression support.

[0014] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the bottom surface of the foundation platform is fixed with foundation piles, which are used to be buried below the ground surface.

[0015] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the frame is composed of frame beams, frame columns and supports; the frame beams are arranged in a grid pattern, and the frame columns are connected to the intersections of the frame beams.

[0016] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the support is a diagonal brace, which is fixed on the diagonal of the grid space formed by the frame beam and the frame column.

[0017] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the vertical tension-compression support is in a compressed state.

[0018] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, a tension-compression energy dissipation damper is also provided at the connection of the vertical tension-compression support.

[0019] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the bottom surface of the frame is divided into a middle area and an outer area located on both sides of the middle area. The bottom end of the frame column in the middle area is connected to the rotating hinge support, and the bottom end of the frame column in the outer area is connected to the vertical tension and compression support.

[0020] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the aspect ratio and stiffness ratio of the frame are adapted to the rocking reset deformation requirements of the frame.

[0021] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an overall swaying self-resetting frame-support structure. For frame structures with long continuity, through a controllable overall swaying mechanism, self-resetting mechanism, and energy dissipation mechanism, the damage to the structure under strong earthquakes is reduced, ensuring reliable connection between the upper structures under the action of horizontal seismic forces, and performing swaying motion of the overall structure. Moreover, the residual deformation of the structure after the earthquake is small, and it can maintain an acceptable level of function. Attached Figure Description

[0030] 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.

[0031] See appendix Figure 1 To be continued Figure 4 This utility model discloses an integral rocking self-resetting frame-support structure, comprising:

[0032] Foundation cap 6;

[0033] The bottom ends of the frame columns 12 in the middle of the frame 1 are connected to the top surface of the foundation 6 through the rotating hinge support 3. The bottom ends of the frame columns 12 on both sides of the frame 1 are connected to the top surface of the foundation 6 through the vertical tension and compression supports 4. When the frame 1 rotates with the rotating hinge support 3 as the fulcrum, the vertical tension and compression supports 4 provide elastic force in the vertical direction.

[0034] In this embodiment, the rotating hinge support 3 only produces a rotation angle and does not cause horizontal or vertical displacement. When subjected to earthquake action, the rotating hinge support 3 provides tension to the rocking structure.

[0035] To further optimize the above technical solution, a horizontal limiting device 5 for the support is also fixed on the top surface of the frame 1. The number of horizontal limiting devices 5 is the same as the number of vertical tension and compression supports 4, and they are located one-to-one on the outside of the vertical tension and compression supports 4. The horizontal limiting device 5 restricts the horizontal displacement of the vertical tension and compression supports 4.

[0036] To further optimize the above technical solution, the horizontal limiting device 5 of the support is a rectangular cylinder arranged around the vertical tension and compression support 4.

[0037] To further optimize the above technical solution, foundation piles 7 are fixed to the bottom surface of the foundation cap 6. The foundation piles 7 are buried below the ground surface to fix the overall structure.

[0038] To further optimize the above technical solution, the frame 1 is composed of frame beams 11, frame columns 12 and supports 13; the frame beams 11 are arranged in a grid pattern, and the frame columns 12 are connected to the intersections of the frame beams 11.

[0039] In this embodiment, the superstructure is a frame-braced structure, which can be either a steel frame-braced structure or a concrete frame-braced structure. In this frame-braced structure, the bracing can be a standard brace, a buckling-restrained energy-dissipating brace, a self-resetting brace, or a braced damper.

[0040] In other embodiments, the support 13 is a diagonal brace, which is fixed on the diagonal of the grid space formed by the frame beam 11 and the frame column 12.

[0041] To further optimize the above technical solution, the vertical tension-compression support 4 is in a compressed state, and its stiffness design meets the requirements for bearing the vertical load of the superstructure.

[0042] To further optimize the above technical solution, a tension-compression energy dissipation damper is also provided at the connection of the vertical tension-compression support 4 to reduce the seismic response of the structure.

[0043] See appendix Figure 5 The bottom surface of frame 1 is divided into a middle section 81 and an outer section 82 located on both sides of the middle section 81. The bottom end of the frame column 12 in the middle section 81 is connected to the rotating hinge support 3, and the bottom end of the frame column in the outer section is connected to the vertical tension and compression support.

[0044] To further optimize the above technical solution, the height-to-width ratio and stiffness ratio of frame 1 are adapted to the swaying and resetting deformation requirements of frame 1. The height-to-width ratio is the ratio of the height to the width of the superstructure; the stiffness ratio is the ratio of the rotational stiffness of the superstructure to the rotational stiffness of the support; the stiffness of the superstructure is the force required to generate a unit displacement at the top; the greater the stiffness of the superstructure, the greater its ability to resist its own deformation.

[0045] Under the action of the rotating hinge support 3, the vertical tension and compression support 4, and the horizontal limiting device 5, the frame 1 will not slide in any direction in the plane relative to the foundation platform 6, which strictly constrains the horizontal displacement of the frame 1. Under the action of earthquake, the frame 1 will produce the overall swaying motion of the structure.

[0046] Under the action of horizontal seismic force, the vertical displacement allowed by the vertical tension-compression support 4 and the limit rotation angle provided by the rotating hinge support 3 provide constraints on the sway amplitude of the superstructure.

[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
