The damage visualization supporting type metal shear damper comprises a connecting plate and an energy consumption plate, wherein the connecting plate and the energy consumption plate are made of metal, holes are formed in the surface of the energy consumption plate, and the connecting plate is connected with the energy consumption plate in the mode of the scheme I or the scheme II. The metal material can be selected from common steel, the outer surface of the damper is coated with a fireproof material, and the melting point of the metal material such as the steel is more than 1500 ℃, so that the metal material has good fireproof performance.
Example one
The connection mode is a first scheme, referring to fig. 1-6, the connection plate includes end plates 11 and reinforcing plates 31, the end plates 11 are two and are parallel to each other and transversely disposed, the energy dissipation plate is two square shear plates 21 and is parallel to each other and longitudinally disposed between the two end plates 11, two end faces of the square shear plates 21 are respectively connected and fixed with opposite surfaces of the two end plates 11, and the square shear plates 21 and the end plates 11 form a cubic structure. A reinforcing plate 31 is provided at the center of the adjacent square shear plates 21 for increasing the joining strength of the square shear plates 21. No holes are formed in the middle slender portion of the square shear plate 21, where the reinforcing plate 31 is fixed.
Because the rigidity of the end plate 11 is high, and the surface of the square shear plate 21 is provided with holes, the square shear plate is easy to generate shearing plastic deformation when being pulled or pressed, energy is dissipated, and the aim of shock absorption is fulfilled. The end plate 11 and the reinforcing plate 31 are used for connecting the plurality of mutually parallel square shear plates 21, so that the plurality of square shear plates 21 can be sheared and deformed simultaneously, and the end plate 11 and the reinforcing plate 31 cannot yield under the action of an earthquake and are always in an elastic state. The square shear plate 21 is firstly subjected to shear deformation in an elastic stage in the early earthquake stage, energy is not consumed at the moment, the square shear plate 21 is continuously subjected to compression deformation and enters plastic deformation, and the plastic deformation consumes energy, so that the energy input into a main body structure by the earthquake is consumed, and the damage of the main body structure caused by the earthquake is reduced. The plastic shear deformation drives the end plate 11 and the reinforcing plate 31 to displace, and the relative displacement of the end plate 11 and the reinforcing plate 31 is the shear deformation value of the square shear plate 21.
Because the middle slender part of the square shear plate 21 is not provided with a hole and does not participate in shearing deformation, under the action of seismic force, the slender part of the section can generate deformation outside the plane where the square shear plate 21 is located, and the deformation mode is as follows: the square shear plate 21 bulges outwards when being pressed, the square shear plate 21 is concave when being pulled, the shear deformation history information of the damper can be obtained by observing the deformation of the long and thin part outside the plane, whether the damping device needs to be maintained or replaced after an earthquake is judged, the damage after the earthquake can be directly observed, and the damage visualization is achieved.
The number of the square shear plates 21 can be a plurality of square shear plates, and the number of the square shear plates can be flexibly set according to the magnitude of the load force so as to meet the actual requirement of the load force. Relevant experiments prove that when the four square shear plates 21 are adopted, the bearing capacity and the energy consumption capacity of the damper are ideal. The metal shear damper has the advantages of small volume, small occupied space and convenience in installation and maintenance. The square shear plate 21 can be vertically placed or horizontally placed, and the volume of the whole metal damper is unchanged. The end plate 11 is a rectangular steel plate, an i-steel or a square steel pipe, and the end plate 11 may take different forms according to the number and arrangement of the square shear plates 21. The end plate 11, square shear plate 21 and reinforcement plate 31 may be made of steel or other high performance metal material with the designation Q235, Q345 or Q390.
As shown in fig. 3-6, the shape of the opening of the square shear plate 21 may be one of a long strip, an oval, a diamond, or a rectangle with rounded corners, or a combination thereof. The initial rigidity of the square shear plate 21 can be changed by changing the form and the number of the openings, so that the bearing capacity and the energy consumption capacity of the square shear plate 21 are changed, and the actual energy consumption requirement is further met. The metal shear damper can be suitable for shock absorption and shock absorption under various conditions, has a simple structure, is convenient to use, overcomes various defects caused by lead shear dampers and dampers with complex structures in the prior art, and reduces damage to a main body structure caused by earthquakes.

The I-shaped shear plates 22 are fixed at two ends of the I-shaped long straight plate 12, the web plate of the energy dissipation plate 22 is vertically intersected with and fixedly connected with two ends of the web plate of the connecting plate 12, and the web plate of the I-shaped shear plate 22 is provided with a hole. Since the i-shaped long straight plate 12 has a long length, the metal shear damper of the present embodiment is suitable for frame support.
The web of the i-shaped shear plate 22 is apertured to form a shear deformation zone under load. When an earthquake occurs, the load caused by the earthquake is input into the main body structure and is transmitted to the metal shear damper of the second embodiment, and the pressure is transmitted to the I-shaped long straight plate 12 through the I-shaped shear plate 22 and then transmitted to the I-shaped shear plate 22 at the other end through the I-shaped long straight plate 12. Through stress analysis, two shearing areas close to the shearing plate are formed among the shearing plate, the long straight plate and the shearing plate, and the web of the I-shaped shearing plate 22 is subjected to shearing force to generate shearing deformation. Firstly, the shear deformation is in the elastic stage, and energy is not consumed at the moment; the I-shaped shear plate 22 continues to be pressed and deformed to enter a plastic stage, and at the moment, the plastic deformation consumes energy, so that the energy input into the main structure of the earthquake is consumed, and the effect of shock absorption is achieved.
The length of the I-shaped long straight plate 12 can be changed according to the size of the frame structure, so that the frame structure can adapt to frame structures with different sizes, and the adjustment is flexible and convenient, and the application range is wide. The required bearing capacity of the supporting metal shear damper is different due to different loads of the frame structure. In this scheme, when the bearing capacity that needs the difference, can realize through the length that changes I shape shear plate 22, the length of I shape shear plate 22 is big more, and the distance in shear zone is also big more, and corresponding bearing capacity can grow, and ultimate power consumption ability also can increase thereupon. In addition, as in the first embodiment, the form and number of the openings in the web of the i-shaped shear plate 22 may be changed to adjust the initial stiffness of the shear plate, and generally, the smaller the number and size of the openings, the stronger the initial stiffness of the shear plate and the larger the bearing capacity, and otherwise, both the initial stiffness and the bearing capacity are decreased.

In the embodiment, the eight square shear plates 21 participate in the shear deformation, so that the initial rigidity is high, the energy consumption capability is high, the axial deformation is less, and the shear deformation is suitable for the condition with higher bearing capacity requirement. Since the cross-shaped long straight plate 13 is long in length, the metal shear damper of the present embodiment is suitable for frame support.
