Description

Technical Field

[0001] The utility model relates to an adaptive energy dissipation damper supporting component, which can be used for a supporting component in an assembled frame and can also be used in a corresponding reinforcement field. Background Art

[0002] The traditional seismic design method is mainly based on "hard resistance" as the main approach, by increasing the cross-sectional size of the structure (beams and columns) and increasing the reinforcement to resist earthquakes. As a result, the larger the cross-sectional size, the greater the overall stiffness, the greater the earthquake effect, and the larger the required cross-sectional size and reinforcement. In this vicious cycle, not only the safety of the structure cannot be guaranteed, but it is also very uneconomical. In some specific parts of the building structure, after the installation of energy-absorbing components, the dynamic response of the structure under the action of the earthquake is effectively controlled. At this time, the structure becomes an energy dissipation and shock-absorbing structure. Compared with general building structures, after the installation of energy-absorbing components, it is equivalent to providing the lateral stiffness of the structure and adding an anti-seismic line of defense. When the structure is subjected to an earthquake, the energy-absorbing damper component first yields to dissipate energy, reducing the seismic energy suffered by the main structure to achieve the effect of protecting the main structure. Conventional buckling brace components are first-order energy-absorbing components. After buckling, the stiffness of the support decreases, resulting in increased lateral deformation of the structure despite energy consumption under a large earthquake, causing excessive deformation damage to non-structural components or structural components, which is not conducive to post-earthquake repair.

[0018] The present invention is described in detail below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, an adaptive energy dissipation damper support member comprises an external steel frame 5, four parallel arranged double X-shaped steel plates 1-4 of the same shape fixedly connected to the external steel frame 5, a middle steel plate 6 and a connecting end plate 7 with ear holes; the external steel frame 5 is a plate-shaped rectangular or square frame structure, and four double X-shaped steel plates 1-4 of the same shape are fixed inside two opposite frames, the upper and lower parts of the double X-shaped steel plates 1-4 are X-shaped steel plates of the same shape, and the two X-shaped steel plates are symmetrical about the central axis of the external steel frame 5;

[0020] The arrangement order of the double X-shaped steel plates 1 to 4 inside the external steel frame 5 from left to right is double X-shaped steel plate 4, double X-shaped steel plate 2, double X-shaped steel plate 3, and double X-shaped steel plate 1;

[0021] The ratio of the end width value to the middle width value of the double X-shaped steel plate 1 is 3 to 3.75;

[0022] The four X-shaped steel plates 1-4 and the external steel frame 5 can be formed by cutting and hollowing out a whole steel plate;

[0023] On the middle steel plate 6, holes for accommodating the X-shaped steel plate 2-4 are arranged according to the position of the X-shaped steel plate 2-4, and a certain free gap is reserved between each hole and the X-shaped steel plate 2-4;

[0024] The middle steel plate 6 is welded to the X-shaped steel plate 1. The transverse free gap between the middle steel plate 6 and the X-shaped steel plate 2 is 2-4 mm, the transverse free gap between the middle steel plate 6 and the X-shaped steel plates 3 and 4 is 4-6 mm, and the longitudinal free gap between the middle steel plate 6 and the X-shaped steel plates 2, 3, and 4 is 5 mm.

[0025] The end of the middle steel plate 6 is welded to the right connecting end plate 7 with ear holes; the outer steel frame 5 is welded to the left connecting end plate 7 with ear holes.

[0026] When the structure is subjected to a small horizontal wind load or a small earthquake, the middle steel plate 6 undergoes a small displacement along the plate transverse direction, which in turn drives the X-shaped steel plate 1 to undergo elastic deformation to dissipate energy, while the other X-shaped steel plates do not deform and are not activated; when the structure is subjected to a moderately strong wind or a moderate earthquake, the displacement of the middle steel plate 6 increases, and due to the limitation of the hole position on the middle steel plate, it drives the X-shaped steel plate 2 to undergo elastic deformation, and at the same time, the X-shaped steel plate 1 undergoes elastic-plastic deformation to dissipate energy together, increasing the stiffness of the energy dissipation damper support component and generating a two-order energy dissipation capacity; when the structure is subjected to a strong wind or a large earthquake, the displacement of the middle steel plate 6 continues to increase, and due to the further limitation of the hole position of the steel plate, the X-shaped steel plates 3 and 4 are driven to undergo elastic deformation and participate in energy dissipation, and at the same time, the stiffness of the energy dissipation damper support component is further increased, generating an adaptive energy dissipation capacity. At this time, all four X-shaped energy dissipation steel plates are activated and participate in energy dissipation, effectively reducing the damage to the structural components.
