Embodiment 1

[0041] Without loss of generality, as Figure 1~2 As shown, the present invention provides a shear type staged yield metal damper, comprising: two steel flange plates 100 placed in parallel and a first rectangular rectangular plate fixed between the two steel flange plates The energy dissipation steel plate 200 and the second rectangular energy dissipation steel plate 300; the first rectangular energy dissipation steel plate 200 and the second rectangular energy dissipation steel plate 300 have different yield strengths; the two steel flange plates 100 are provided with The steel side panels 400 required by the first rectangular energy-dissipating steel plate 200 and the second rectangular energy-dissipating steel plate 300 are fixed.

[0042] Preferably, the present invention can realize the fast connection between the adjacent parts of the above-mentioned structure by welding.

[0043]The present invention adopts two rectangular energy-dissipating steel plates with differen...

Embodiment 2

[0050] Such as Image 6 As shown, in this embodiment, on the basis of embodiment 1, in order to achieve the technical effect of longitudinal segmental yielding, the first rectangular energy-dissipating steel plate and the second rectangular energy-dissipating steel plate are placed up and down. Further expand the application occasions of the above-mentioned shear type step-by-step yield metal damper.

[0051] Further, such as Figure 7 As shown, in order to strengthen the fastening connection between the first rectangular energy-dissipating steel plate and the second rectangular energy- The solid connection of the second rectangular energy-dissipating steel plate provides a more stable structural support.

Embodiment 3

[0053] Such as Figure 8 As shown, in order to meet the requirement of staged energy dissipation, when the steel flange plate 100 is placed horizontally, the first rectangular energy dissipation steel plate 200 and the second rectangular energy dissipation steel plate 300 are placed back and forth. The application field of the above-mentioned shear type stepwise yield metal damper is further broadened.

[0054] It should be noted that since the firmness of fixing the first rectangular energy-dissipating steel plate and the second rectangular energy-dissipating steel plate by adding stiffeners has been involved in the foregoing embodiments, the technical means are not the core invention points of this embodiment. Therefore, in this embodiment, its related structure will not be illustrated and described in detail.

Abstract

The invention provides a shearing type staged yield metal damper which solves the technical problems that an existing metal damper can not meet the requirements for wind vibration, small shock and large shock energy consumption at the same time, and is inconvenient to install and maintain. The metal damper structurally comprises two steel flange plates arranged in parallel, a first rectangular energy consumption steel plate and a second rectangular energy consumption steel plate, wherein the first rectangular energy consumption steel plate and the second rectangular energy consumption steel plate are fixedly arranged between the two steel flange plates. The first rectangular energy consumption steel plate and the second rectangular energy consumption steel plate have different kinds of yield strength. Steel side wing plates needed by the first rectangular energy consumption steel plate and the second rectangular energy consumption steel plate are arranged between the two steel flange plates. According to the metal damper, the two rectangular energy consumption steel plates with the different kinds of yield strength are adopted as the core energy consumption parts of the yield metal damper, under the conditions of wind vibration, small shock and the large shock, the corresponding energy consumption requirements can be met, the structure is simple and easy to realize, and the metal damper is more convenient to install compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of building energy dissipation and shock absorption, in particular to a shear-type staged yield metal damper in a structure passive shock absorption control system. Background technique [0002] In the existing technology, with the continuous emergence of a large number of complex high-rise and super high-rise building structures, new challenges have been brought to the seismic design—the building structure must not only meet the design requirements of bearing capacity, but also achieve the goal of performance-based design. In the structural layout form of the prior art, the design cross-sections of beams, columns and other components are all very large, which leads to an increase in the self-weight of the structure, that is, the seismic response; in addition, after the earthquake shock, even if the building with the traditional structure does not collapse, it will still collapse. It will bring higher repair...
