Description

Technical Field

[0001] The invention relates to the technical field of earthquake-resistant structural systems, and more particularly to an integral rocking self-resetting frame-support structure. Background Art

[0002] With the acceleration of urbanization in China, the height and complexity of buildings are increasing. In areas where earthquakes occur frequently, buildings must not only withstand daily static loads, but also have good earthquake resistance to cope with possible extreme natural disasters. Therefore, the earthquake resistance and stability of structures have become increasingly important. Although traditional frame structures can meet the structural bearing requirements to a certain extent, they often experience large deformations when facing extreme loads, and may even cause structural damage and collapse. Therefore, how to improve the earthquake resistance of building structures has become an important issue that needs to be urgently solved in the field of engineering technology.

[0003] In recent years, self-resetting structure technology has gradually attracted attention. In previous designs, frame structures usually use a rigid connection method to fix the upper structure to the foundation. Although this design performs well under static loads, it is easy to cause bending, shearing and bending-shear deformation of the structure under dynamic loads such as earthquakes, resulting in permanent deformation and structural damage. The self-resetting structure can quickly restore the structure to its original state through its own design after the action of loads such as earthquakes, thereby avoiding the permanent deformation of traditional structures after earthquakes. This technology not only improves the durability of the structure, but also reduces the cost of maintenance and reinforcement.

[0004] However, the existing self-righting frame structure still has some shortcomings, such as limited self-righting ability, construction complexity and high requirements on material properties.

[0005] Therefore, developing a structure that can improve its overall seismic resistance and self-reset ability while ensuring structural safety has important practical significance and application value. Summary of the invention

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

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

[0008] An integral swing self-resetting frame-support structure, comprising:

[0009] Foundation cap;

[0010] The frame, the bottom end of the frame column located in the middle of the frame is connected to the top surface of the foundation pedestal through a rotating hinge support, and the bottom ends of the frame columns located on both sides of the frame are connected to the top surface of the foundation pedestal through vertical tension and compression supports. When the frame rotates with the rotating hinge support as the fulcrum, the vertical tension and compression supports provide elastic force in the vertical direction.

[0011] Through the above technical solution, the present invention provides an integrally swaying self-resetting frame-support structure. Compared with the prior art, the overall swaying of the frame, the deformation and rotation of the bottom vertical tension and compression support and the hinge support effectively absorb and disperse the seismic energy, and reduce the impact of vibration on the structure. The structure has strong stability and strong self-resetting ability, avoiding the permanent deformation that may occur in traditional frame structures after an earthquake, reducing the cost of maintenance and reinforcement, and protecting the safety of the structure.

[0012] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, a support horizontal limiting device is also fixed to the top surface of the frame, the number of the support horizontal limiting devices 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, and the support horizontal limiting device limits the horizontal displacement of the vertical tension and compression supports.

[0013] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the support horizontal limiting device 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, foundation piles are fixed to the bottom surface of the foundation pedestal, and the foundation piles are used to be buried below the ground surface.

[0015] Preferably, in the above-mentioned integral rocking self-righting frame-support structure, the frame is composed of frame beams, frame columns and supports; the frame beams are arranged in layers in a grid form, 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, and the diagonal brace is fixed on the diagonal line of the grid space formed by the frame beams and the frame columns.

[0017] Preferably, in the above-mentioned integral rocking self-resetting frame-support structure, the vertical tension and 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 between the vertical tension-compression supports.

[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 outer areas located on both sides of the middle area, the bottom ends of the frame columns in the middle area are connected to the rotating hinge support, and the bottom ends of the frame columns in the outer areas are connected to the vertical tension and compression supports.

[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 and resetting deformation requirements of the frame.

[0021] It can be seen from the above technical solution that, compared with the prior art, the present invention discloses an overall swinging self-resetting frame-support structure. For a frame structure with a long continuity, the present invention reduces the damage of the structure under a strong earthquake through a controllable overall swinging mechanism, a self-resetting mechanism, and a device energy consumption mechanism, ensures reliable connection between the upper structures under the action of the horizontal force of the earthquake, and performs the swinging movement of the overall structure. The residual deformation of the structure after the earthquake is small and can maintain an acceptable functional level. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] 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.

[0031] See attached Figure 1 To Attachment Figure 4 The embodiment of the present invention discloses an integral rocking self-resetting frame-support structure, comprising:

[0032] Foundation cap 6;

[0033] Frame 1, the bottom end of the frame column 12 located in the middle of the frame 1 is connected to the top surface of the foundation pedestal 6 through a rotating hinge support 3, and the bottom ends of the frame columns 12 located on both sides of the frame 1 are connected to the top surface of the foundation pedestal 6 through a vertical tension and compression support 4. When the frame 1 rotates with the rotating hinge support 3 as the fulcrum, the vertical tension and compression support 4 provides an elastic force in the vertical direction.

[0034] In this embodiment, the rotating hinge support 3 only generates an angle of rotation without causing horizontal or vertical displacement. When subjected to an earthquake, the rotating hinge support 3 provides a pulling force for the rocking structure.

[0035] In order to further optimize the above technical solution, a support horizontal limit device 5 is also fixed to the top surface of the frame 1. The number of the support horizontal limit devices 5 is the same as the number of the 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 support horizontal limit devices 5 limit the horizontal displacement of the vertical tension and compression supports 4.

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

[0037] In order to further optimize the above technical solution, foundation piles 7 are fixed to the bottom surface of the foundation pedestal 6, and the foundation piles 7 are used to be buried below the ground surface to fix the overall structure.

[0038] In order 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 layers in a grid form, and the frame columns 12 are connected to the intersections of the frame beams 11.

[0039] In this embodiment, the upper structure is a frame-support structure, and the type of this structure is applicable to a steel frame-support structure or a concrete frame-support structure. In this frame-support structure, the support can be a common support, a buckling-resistance energy-dissipating support, a self-resetting support, or a support-type damper.

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

[0041] In order to further optimize the above technical solution, the vertical tension and compression support 4 is in a compressive state, and its stiffness design meets the requirement of bearing the vertical load of the superstructure.

[0042] In order 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 attached Figure 5 The bottom surface of the frame 1 is divided into a middle area 81 and outer areas 82 located on both sides of the middle area 81. The bottom ends of the frame columns 12 in the middle area 81 are connected to the rotating hinge support 3, and the bottom ends of the frame columns in the outer areas are connected to the vertical tension and compression supports.

[0044] In order to further optimize the above technical solution, the aspect ratio and stiffness ratio of frame 1 are adapted to the swing reset deformation requirements of frame 1, wherein the aspect 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 produce 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 support horizontal limit device 5, the frame 1 will not slide in any direction within the plane relative to the foundation pedestal 6, and the horizontal displacement of the frame 1 is strictly constrained. Under the action of an earthquake, the frame 1 produces a swaying movement of the entire structure.

[0046] Under the action of earthquake horizontal force, the vertical displacement allowed by the vertical tension and compression support 4 and the limit rotation angle that can be provided by the rotary hinge support 3 provide limiting conditions for the swing amplitude of the superstructure.

[0047] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0048] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one 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 will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
