Description

A controllable, swaying frame-shear wall structure Technical Field

[0001] This invention relates to the field of seismic resistance technology in civil engineering, and more specifically to an integrally swaying controllable frame-shear wall structure. Background Technology

[0002] Traditional earthquake-resistant structures primarily aim to control the strength and ductility of the structure. Bearing capacity is designed for minor earthquakes, while ductility and deformation are checked for major earthquakes to ensure the structure does not collapse. However, while traditional structures can withstand strong earthquakes through existing design codes, they suffer severe damage, making post-earthquake repair difficult or prohibitively expensive. For critical engineering structures, it is essential not only to effectively protect lives and property after a strong earthquake but also to quickly restore their normal functionality to avoid further indirect losses. The 2010 Christchurch earthquake in New Zealand demonstrated that the indirect and direct losses caused by strong earthquakes to building structures are on the same order of magnitude.

[0003] Self-resetting swaying structures are an effective structural form for mitigating seismic damage, but existing swaying structures have failed to achieve overall deformation control and lack seismic design methods. Therefore, developing resilient structures that can effectively reduce seismic losses and proposing seismic design methods are urgent problems to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides an integrally swaying controllable frame-shear wall structure, which aims to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] Preferably, in the above-mentioned integral rocking controllable frame-shear wall structure, a shear reinforcement mechanism is further provided between the outer bottom surface of the axial force transmission steel box and the top surface of the base plate.

[0014] Preferably, in the above-mentioned integral rocking controllable frame-shear wall structure, the rotating hinge support includes a base fixedly connected to the top surface of the foundation and a rotating platform fixedly connected to the bottom end of the shear wall, and a rotating hinge support tension-compression elastic element is connected between the base and the rotating platform.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Referring to Figure 1, an embodiment of the present invention discloses an integrally swaying controllable frame-shear wall structure, comprising:

[0032] Shear wall 3, the outer side of shear wall 3 is fixed to form a frame base by frame columns 1 and frame beams 2, and the bottom end of frame columns 1 on the outer side of the frame base is fixedly connected to pier support 4.

[0034] Rotate hinge support 6, the top of rotating hinge support 6 is connected to the bottom end of shear wall 3, and the bottom of rotating hinge support 6 is connected to the foundation.

[0035] Referring to Figure 5, the elastic support 5 for the frame column includes a base plate 58 connected to the foundation. A steel core column 51 is fixed to the top surface of the base plate 58. An axial force transmission steel box 53 is fitted on the outer side of the steel core column 51. The top of the steel core column 51 extends out of the axial force transmission steel box 53, and a core column protective shell 52 covering the top of the steel core column 51 is fixed to the top surface of the axial force transmission steel box 53. There is a gap between the inner top surface of the core column protective shell 52 and the top surface of the steel core column 51. A combined buffer layer 57 is provided between the outer bottom surface of the axial force transmission steel box 53 and the base plate 58. The top surface of the core column protective shell 52 is fixed to the bottom end of the pier support 4. A disc spring 56 is fitted on the steel core column 51, and a nut 54 is locked to the top of the steel core column 51. The nut 54 presses the disc spring 56 against the inner bottom surface of the axial force transmission steel box 53.

[0036] The gap between the inner top surface of the core column protective shell 52 and the top surface of the steel core column 51 allows the disc spring 56 to undergo vertical deformation.

[0037] To further optimize the above technical solution, in the above-mentioned overall sway controllable frame-shear wall structure, the combined buffer layer 57 includes stacked steel plates and a thick rubber layer.

[0038] To further optimize the above technical solution, in the above-mentioned overall swing controllable frame-shear wall structure, a spring upper pad 55 is sleeved on the steel core column 51, and the spring upper pad 55 is pressed against the top of the nut 54 and the disc spring 56.

[0039] To further optimize the above technical solution, in the aforementioned integral rocking controllable frame-shear wall structure, a shear reinforcement mechanism 59 is also provided between the outer bottom surface of the axial force transmission steel box 53 and the top surface of the base plate 58. In this embodiment, the shear reinforcement mechanism 59 is a damper.

[0040] Referring to Figures 2 to 4, the rotating hinge support 6 includes a base 63 fixedly connected to the top surface of the foundation and a rotating platform 61 fixedly connected to the bottom end of the shear wall 3. A rotating hinge support tension-compression elastic element 64 is connected between the base 63 and the rotating platform 61.

[0041] In this embodiment, the rotating hinge support tension-compression elastic element 64 can adopt the same structure as the frame column elastic support 5 provided in this embodiment.

[0043] To further optimize the above technical solution, a rubber pad layer is provided in the rotation limiting groove 631 of the above-mentioned integral swing controllable frame-shear wall structure.

[0044] To further optimize the above technical solution, in the above-mentioned overall swing controllable frame-shear wall structure, the bottom surface of the rotation limiting groove 631 has a spherical core 62 in the middle, and the bottom surface of the rotating platform 61 has a spherical reserved groove 611 that rotates and cooperates with the spherical core 62.

[0045] To further optimize the above technical solution, in the above-mentioned overall swing controllable frame-shear wall structure, the inner surface of the spherical reserved groove 611 is provided with a polytetrafluoroethylene plate.

[0046] Referring to Figures 3 and 4, a slot is provided on the upper end surface of the rotation limiting groove 631 for the protrusion to enter. The protrusion of the rotating table 61 can enter the rotation limiting groove 631 through the slot to realize the cooperation between the ball core 62 and the spherical reserved groove 611. Then, rotating the rotating table 61 to avoid the slot can prevent it from falling out.
