[0040] In the embodiment, the upper flange plate 1 and the lower flange plate 2 can be selected from high-quality steel plate, which is arranged in parallel to form the main bearing surface of the energy dissipation beam. The web plate 3 is located between the upper flange plate 1 and the lower flange plate 2, and the length of the web plate 3 matches the upper flange plate 1 and the lower flange plate 2. The two sides of the web plate 3 are respectively provided with a plurality of corresponding transverse rib plates 4, and the upper and lower ends of the transverse rib plates 4 are respectively and firmly connected with the upper flange plate 1 and the lower flange plate 2, and the connection mode is preferably angle welding. The arrangement of the transverse rib plate 4 not only enhances the shear capacity of the energy dissipation beam, but also effectively prevents the instability of the web plate 3 under stress, thereby improving the overall rigidity and stability of the energy dissipation beam.

[0041] At the two side ends of the web plate 3, the upper flange plate 1 and the lower flange plate 2, connecting assemblies 5 are respectively arranged. The connecting assemblies 5 are made of high-strength bolts or other reliable detachable connection modes, and are used for connecting with the external frame beam 6. The detachable connection design enables the energy dissipation beam to be quickly and simply replaced when damaged after the earthquake, without the need for complex operations such as on-site welding, thereby greatly improving the construction efficiency and maintainability.

[0042] In the embodiment, the connecting assembly 5 comprises end plates 51 fixedly connected to both side ends of the web plate 3, the upper flange plate 1 and the lower flange plate 2. The end plates 51 are uniformly provided with a plurality of connecting holes, and the connecting holes are detachably connected to the frame beam 6 through fasteners 53.

[0043] Specifically, the end plate 51 can be a metal plate fixedly connected to both side ends of the web plate 3, the upper flange plate 1 and the lower flange plate 2 of the energy dissipation beam. It plays a bridge role in connecting the energy dissipation beam and the frame beam 6, and ensures the stable connection between the two. A plurality of connecting holes are uniformly arranged on the end plate 51. Correspondingly, the side end of the frame beam 6 is also provided with a mounting plate corresponding to the end plate 51, and the mounting plate is provided with corresponding mounting holes corresponding to the connecting holes of the end plate 51, and is fixedly connected to the end plate 51 through fasteners 53 such as high-strength bolts.

[0044] Further, as a preferred embodiment of the present scheme but not limited, a diagonal corrugated plate 7 for energy dissipation and seismic resistance is arranged between any two of the transverse rib plates 4.

[0045] In the embodiment, the diagonal corrugated plate 7 is arranged between any two of the transverse rib plates 4 by angle welding, and the specific position is preferably coincided with the diagonal of the rectangular face formed between the two transverse rib plates 4. The material and form of the diagonal corrugated plate 7 are preferably selected from corrugated steel plates with trapezoidal corrugations, and the corrugation shape can also be selected from triangular corrugations, rectangular corrugations, sinusoidal corrugations, etc. The arrangement of the diagonal corrugated plate 7 not only increases the overall stiffness of the energy dissipation beam, but more importantly, under the action of dynamic load such as earthquake, the deformation of the corrugation can absorb and dissipate a large amount of energy, thereby improving the seismic performance of the structure.

[0046] Further, as a preferred embodiment of the present scheme but not limited, the diagonal corrugated plates 7 on both sides of the midspan of the web plate 3 are symmetrically arranged.

[0047] In the embodiment, the energy dissipation beam is divided into left and right parts with the midspan of the web plate 3 as the boundary. The diagonal corrugated plates 7 on both sides of the midspan line are symmetrically arranged, that is, the number, shape, inclination angle and other parameters of the corrugated plates on both sides are consistent. Such symmetrical layout helps to achieve force balance of the structure, reduces additional stress caused by asymmetric arrangement, and thus improves the overall stability and durability of the structure.

[0048] Further, as a preferred embodiment of the present application but not limited, the distance between any two adjacent transverse rib plates 4 is equal, and the distance between the first and last transverse rib plates 4 to the edges of the web plate 3 is 150 mm, so as to facilitate the installation of the connecting assembly 5. The equal-distance transverse rib plate 4 layout helps to achieve uniform distribution of internal stress of the energy dissipation beam, reduce stress concentration phenomenon, and improve the overall stability and durability of the structure. By setting the distance between the first and last transverse rib plates 4 to the edges of the web plate 3 to be 150 mm, sufficient space is provided for the installation of the connecting assembly 5, thereby ensuring the stability and reliability of the connection.

[0049] Further, as a preferred embodiment of the present application but not limited, the web plate 3, the upper flange plate 1 and the lower flange plate 2 are in the form of an I-beam.

[0050] In the present embodiment, the web plate 3 is vertically arranged between the upper flange plate 1 and the lower flange plate 2, and the three are formed into an integral whole by angle welding. This structure is similar to an I-beam, so that the energy dissipation beam can fully utilize the shear strength of the web plate and the bending strength of the flange plate when bearing vertical load, thereby improving the overall load-bearing capacity.

[0051] Further, as a preferred embodiment of the present application but not limited, the width of the upper flange plate 1 and the lower flange plate 2 respectively corresponds to the beam width of the frame beam 6; the distance between the upper end surface of the upper flange plate 1 and the lower end surface of the lower flange plate 2, i.e. the height of the energy dissipation beam, corresponds to the beam height of the frame beam 6.

[0052] By ensuring that the width of the flange plate corresponds to the beam width of the frame beam and the height of the energy dissipation beam corresponds to the beam height of the frame beam, the present embodiment significantly improves the stability of the connection between the energy dissipation beam and the frame beam. This stable connection helps to ensure that the eccentrically braced structure can maintain overall stability when bearing load, reducing additional stress caused by loose connection.

[0053] Embodiment 2:

[0054] Please refer to Figures 6-7 , the present embodiment provides a replaceable eccentrically braced energy dissipation beam, which differs from embodiment 1 in that the specific component members and arrangement form of the connecting assembly 5 are different. In the present embodiment, the connecting assembly 5 includes a first upper connecting plate 54 arranged at the upper end surface of the upper flange plate 1 and the frame beam 6, and a first lower connecting plate 55 arranged at the lower end surface of the lower flange plate 2 and the frame beam 6. The first upper connecting plate 54 and the first lower connecting plate 55 are respectively provided with fasteners 53 for fixing the upper flange plate 1 and the lower flange plate 2 to the upper and lower ends of the frame beam 6.

[0055] Specifically, by arranging the first upper connecting plate 54 and the first lower connecting plate 55 at the contact surfaces of the upper flange plate 1 and the lower flange plate 2 and the frame beam 6 respectively and fixing by the fasteners 53, the connection stability between the energy dissipation beam and the frame beam 6 is enhanced, and the overall seismic performance of the structure is improved.

[0056] Further, as a preferred embodiment of the present scheme but not limited, the upper flange plate 1 is provided with a second upper connecting plate 56 at the lower end surface of the joint with the frame beam 6, which forms clamping fixation with the first upper connecting plate 54 and the fastener 53; and the lower flange plate 2 is provided with a second lower connecting plate 57 at the upper end surface of the joint with the frame beam 6, which forms clamping fixation with the first lower connecting plate 55 and the fastener 53.

[0057] In the present embodiment, the second upper connecting plate 56 and the second lower connecting plate 57 are respectively provided with bolt mounting holes corresponding to the first upper connecting plate 54 and the first lower connecting plate 55. By increasing the second upper connecting plate 56 and the second lower connecting plate 57, the first upper connecting plate 54, the first lower connecting plate 55 and the fastener 53 form a clamping fixation structure together, which further enhances the connection stability between the energy dissipation beam and the frame beam and improves the overall seismic performance of the structure. In addition, under the action of extreme loads such as earthquakes, this clamping fixation structure can effectively disperse and resist external forces, reduce stress concentration at the connection between the energy dissipation beam and the frame beam, and thus prolong the service life of the structure.

[0058] Unlike the present embodiment, the connecting assembly 5 in embodiment 1 is directly connected to the end of the frame beam in a detachable manner by the end plate 51 provided with connecting holes. Except for the specific components and connection form of the connecting assembly 5, other specific structures of the present embodiment, such as the arrangement of the inclined corrugated plate 7, are the same as those of embodiment 1, and thus have corresponding beneficial effects, which will not be described here.

[0059] Working principle of the utility model:

[0060] The utility model provides a replaceable eccentrically braced energy dissipation beam, and the energy dissipation beam is composed of an upper flange plate, a lower flange plate and a web plate, forming an I-shaped structure, which can make full use of the shear strength of the web plate and the bending strength of the flange plate when the energy dissipation beam bears vertical load, and improve the overall bearing capacity.

[0061] A plurality of corresponding transverse rib plates are arranged on both sides of the web plate, which not only enhances the shear capacity of the energy dissipation beam, but also effectively prevents the instability of the web plate under stress, thereby improving the overall stiffness and stability of the energy dissipation beam.

[0062] The two side ends of the energy dissipation beam are provided with a connecting assembly for detachable connection with an external frame beam.

[0063] The connecting assembly can adopt various forms, such as the clamping and fixing structure composed of the first upper connecting plate, the first lower connecting plate, the second upper connecting plate, the second lower connecting plate, etc.

[0064] The oblique corrugated plate arranged in the energy dissipation beam is a key energy dissipation element. Under the action of dynamic load such as earthquake, the deformation of the corrugated plate can absorb and dissipate a large amount of energy, thereby improving the seismic performance of the structure.

[0065] In addition, the symmetrical arrangement of the oblique corrugated plate helps to achieve force balance of the structure, reduce additional stress caused by asymmetric arrangement, and improve the overall stability and durability of the structure.

[0066] In summary, the replaceable eccentrically braced energy dissipation beam proposed by the present application improves the seismic performance of the structure through its unique structural design and detachable connection method, while ensuring that it can be quickly replaced when necessary to restore or maintain the function of the eccentrically braced structure.
