[0026] The following refers to Figures 1-10The multiple energy dissipation structure 10 according to the embodiment of the present application is described, which comprises a column 100, a main beam 200, a node plate 300, a hydraulic mechanism 400, and a buckling-restrained energy dissipation brace 500.

[0027] Specifically, the column 100 can be configured as a steel column with a cross-sectional shape of H type, a rectangular shape, or a groove type, or a lattice column composed of multiple section steels, and the embodiment of the present application does not make specific limitation thereon. The column 100 can be made of a metal material, such as steel, which is a typical metal material and has high strength, good plasticity, and toughness, so as to significantly improve the load-bearing performance of the multiple energy dissipation structure 10.

[0028] The column 100 can provide support for the multiple energy dissipation structure 10, so as to increase the overall rigidity and strength of the multiple energy dissipation structure 10 and ensure the stability of the multiple energy dissipation structure 10. When the building bears a large earthquake, the column 100 can transmit the earthquake energy to the ground, so as to ensure the safety of the building. The uniformly distributed columns 100 can evenly distribute the earthquake energy according to the rigidity, so as to avoid excessive local stress and damage to the multiple energy dissipation structure 10.

[0029] The number of columns 100 can be multiple, and the user can select different numbers of columns 100 according to different buildings. The spacing between the columns 100 can be calculated and determined according to the earthquake energy, earthquake intensity, seismic grade, building layers, building plane, and facade related information of the building, and the user can adjust the different axial distances between the columns 100 according to different buildings.

[0030] Further, the cross-sectional shape of the main beam 200 can be configured as H type, a rectangular shape, or a groove type, and can also be configured as other irregular cross-sectional shapes, and the embodiment of the present application does not make specific limitation thereon. The user can select the main beam 200 with different cross-sectional shapes according to the earthquake energy, span, material, and functional requirements of the multiple energy dissipation structure 10. The opposite ends of the main beam 200 can be fixedly connected with the columns 100 by welding or bolt connection, so as to facilitate the columns 100 to provide support for the main beam 200. The number of main beams 200 can be determined according to the axial distance of the columns 100, and the user can select different numbers of main beams 200 according to different buildings.

[0031] The main beam 200 can transmit seismic energy with the column 100, so as to ensure the stiffness distribution and transmission of the seismic energy, and further ensure the safety of the multiple energy dissipation structure 10.

[0032] Specifically, the node plate 300 can be configured as an irregular plate structure with a 45-degree chamfer at the top two ends, or other irregular plate structures, which are not limited in the embodiments of the present application, and the user can adjust the shape of the node plate 300 according to different application scenarios. The node plate 300 can be fixedly connected with the opposite two ends of the main beam 200 by welding or threaded connection, and then fixedly connected with the column 100 by welding or threaded connection. In this way, the opposite two ends of the main beam 200 can be fixedly connected with the column 100 through the node plate 300. Under the action of the earthquake, the node plate 300 can improve the anti-deformation capacity of the connection point of the main beam 200 and the column 100, so as to ensure the safety of the multiple energy dissipation structure 10.

[0033] The number of node plates 300 can be multiple. The node plate 300 can be hinged with the buckling-restrained energy dissipation brace 500 in the following embodiments through the connection of the pin shaft. During the installation of the pin shaft, the surface of the pin shaft should be kept clean to ensure that the surface of the pin shaft is free of impurities and rust, so that the pin shaft can be smoothly installed. The surface of the pin shaft can also be smeared with lubricating oil, so as to reduce the friction between the pin shaft and the mounting hole (not shown in the figure), and further prolong the service life of the pin shaft. An elastic check ring anti-disengagement device (not shown in the figure) can also be installed between the pin shaft and the mounting hole, so as to greatly improve the stability between the node plate 300 and the buckling-restrained energy dissipation brace 500, and further greatly improve the safety of the multiple energy dissipation structure 10.

[0034] One side of the node plate 300 hinged with the buckling-restrained energy dissipation brace 500 can be fixedly connected with the column 100 through spot welding, and one end of the node plate 300 can be in abutment with the main beam 200. It should be noted that the contact surface angle of the node plate 300 in abutment with the bottom of the main beam 200 can adopt a 45-degree chamfer. In this way, the hydraulic rod 430 in the following embodiments can slide without obstacles.

[0035] Stiffening ribs 310 can be arranged around the node plate 300 hinged with the buckling-restrained energy dissipation brace 500. The shape of the stiffening rib 310 can be configured as a one-letter steel plate. The stiffening rib 310 can be installed around the node plate 300 through welding, so as to improve the local stability of the node plate 300 and avoid instability damage of the node plate 300 due to excessive local stress. The stiffening rib 310 can also enhance the stiffness of the node plate 300 and simultaneously prolong the service life of the node plate 300, and further prolong the working life of the multiple energy dissipation structure 10.

[0036] The hydraulic mechanism 400 can be arranged below the main beam 200 along the height direction of the multiple energy dissipation structure 10 and maintain a certain distance from the main beam 200. This arrangement can prevent the hydraulic mechanism 400 from colliding with the main beam 200 during operation, resulting in damage to the hydraulic mechanism 400 and the main beam 200. The height direction of the multiple energy dissipation structure 10 is Figure 4 The opposite ends of the hydraulic mechanism 400 can be fixedly connected to the columns 100. With this arrangement, when the building is stationary or subjected to relatively small seismic energy, the multiple energy dissipation structure 10 can maintain the static stability of the building through the cooperation of the hydraulic mechanism 400, the columns 100, and the main beams 200. When the building is subjected to relatively large seismic energy, the hydraulic mechanism 400 can dissipate most of the kinetic energy transferred between the columns 100 and the main beams 200 through its operation, thereby ensuring the safety of the building.

[0037] One end of the buckling-resistance brace 500 can be fixedly connected to the gusset plate 300 via welding, bolting, or other connection methods, while the other end of the buckling-resistance brace 500 can be hinged to the diagonal gusset plate 300 via a pin (not shown). With this arrangement, the buckling-resistance brace 500, together with the columns 100 and main beams 200, can form a frame-centered support structure, thereby improving the overall stability and lateral stiffness of the multiple energy dissipation structure 10. The other end of the buckling-resistance brace 500 can also be connected to the hydraulic mechanism 400 via the gusset plate 300. This facilitates the buckling-resistance brace 500 driving the hydraulic mechanism 400 via the gusset plate 300. Seismic energy can be absorbed through the translation of the buckling-resistance brace 500 and the action of the hydraulic mechanism 400, thereby ensuring the stability of the multiple energy dissipation structure 10.

[0038] Buckling-resistance braces 500 can be installed along the height of the multiple energy dissipation structure 10, at locations where relative displacement between layers at the bottom of the multiple energy dissipation structure 10 is significant. This allows the buckling-resistance braces 500 to offset horizontal seismic effects on key parts of the multiple energy dissipation structure 10, thereby ensuring the safety of the multiple energy dissipation structure 10 and simultaneously reducing the manufacturing cost of the multiple energy dissipation structure 10. Buckling-resistance braces 500 can be constructed of metal, such as low-yield Q235 steel, and flexible materials, significantly improving the ductility of the multiple energy dissipation structure 10 while simultaneously reducing the manufacturing cost of the multiple energy dissipation structure 10.

[0039] Please continue to see Figure 1 As shown, when the building is stationary or subjected to relatively small seismic energy, the buckling-resistance energy dissipation support 500 can provide stable support for the multiple energy dissipation structure 10 to ensure the normal function of the multiple energy dissipation structure 10. At this time, the multiple energy dissipation structure 10 can be a frame-center support structure system.

[0040] Please continue to see Figure 2 and Figure 3 As shown in FIG. 13, when the building is subjected to a large earthquake, the hydraulic mechanism 400 can realize the dynamic conversion of the multiple energy dissipation structure 10 by action, and the multiple energy dissipation structure 10 can be converted from the frame-central bracing structure before the earthquake to the frame-bottom eccentric bracing structure after the earthquake.

Through the conversion of the structural system and the circulation of the hydraulic oil in the hydraulic mechanism 400, the multiple energy dissipation structure 10 can realize the first energy dissipation under strong earthquake; the girder 200 of the frame-bottom eccentric bracing structure after the earthquake increases the energy dissipation beam segment 210 in the following embodiment, and through the structural deformation of the energy dissipation beam segment 210 and the setting of the first limiter 440, the second limiter 450 and the third limiter 460 in the following embodiment, the multiple energy dissipation structure 10 can realize the second energy dissipation under strong earthquake; by setting the buckling-restrained energy dissipation support 500, the lateral stiffness of the multiple energy dissipation structure 10 can be increased and the ductility of the multiple energy dissipation structure 10 can be improved, and at the same time, the buckling-restrained energy dissipation support 500 can fully play the hysteretic energy dissipation capacity of steel due to the characteristic that it will not buckle when being pressed. The stretching and deformation of flexible materials can realize the third energy dissipation of the multiple energy dissipation structure 10 under strong earthquake. Through the three energy dissipations of the multiple energy dissipation structure 10 under strong earthquake, most of the seismic action can be transmitted to the internal energy of the building to convert into mechanical energy to do work, and through the dissipation of energy, the stability and safety of the building under strong earthquake can be ensured.

[0046] It should be noted that the guide rail 600 and the main beam 200 should be installed with a certain spacing, which can ensure that the hydraulic mechanism 400 has a certain space for movement, thereby avoiding damage to the multiple energy dissipation structure 10 caused by the action of the hydraulic mechanism 400.

[0047] Please continue to see Figure 5 , Figure 8 and Figure 9 ​As shown, according to still another embodiment of the present application, the hydraulic mechanism 400 comprises: a hydraulic cylinder 410, which is fixedly connected with the guide rail 600; a piston 420, which is movably sleeved in the interior of the hydraulic cylinder 410, and which divides the interior of the hydraulic cylinder 410 into a first chamber 411 and a second chamber 412, and which is filled with hydraulic oil in the first chamber 411 and the second chamber 412 respectively; and a hydraulic rod 430, a fixed end 431 of which is fixedly connected with the node plate 300, a movable end 432 of which sequentially penetrates through opposite ends of the hydraulic cylinder 410 and the piston 420, and which is fixedly connected with the piston 420, so that the node plate 300 drives the piston 420 to move in the hydraulic cylinder 410 through the hydraulic rod 430.

[0048] Specifically, the hydraulic cylinder 410 can be fixedly connected with the guide rail 600 through bolt connection or welding, so as to ensure that the hydraulic cylinder 410 will not relatively displace during operation, thereby ensuring the safety of the multiple energy dissipation structure 10. During installation of the hydraulic cylinder 410, the central axis of the hydraulic cylinder 410 should be parallel to the extension direction of the guide rail 600, for example, a level tool can be used for measurement and adjustment, so as to ensure that the hydraulic rod 430 in the following embodiments can smoothly and unobstructedly stretch and retract, thereby avoiding collision with other parts during stretching and retracting of the hydraulic rod 430 and causing damage.

[0049] Further, the piston 420 can be configured as an irregular shape with a hollow interior and a plurality of uniform through holes (not shown in the figure), and the cross-sectional shape of the piston 420 should be consistent with the cross-sectional shape of the interior of the hydraulic cylinder 410, so that the piston 420 can be closely sleeved in the interior of the hydraulic cylinder 410. The piston 420 can divide the interior of the hydraulic cylinder 410 into the first chamber 411 and the second chamber 412, and the first chamber 411 and the second chamber 412 are both closed environments, and the first chamber 411 and the second chamber 412 can be filled with hydraulic oil respectively.

[0050] Under strong earthquakes, the hydraulic mechanism 400 starts to act, at this time, the hydraulic oil can flow from the first chamber 411 to the second chamber 412 or from the second chamber 412 to the first chamber 411 through the uniform through holes on the piston 420, thereby effectively converting part of the kinetic energy generated by vibration of the multiple energy dissipation structure 10 into heat energy, thereby reducing the vibration energy of the earthquake action transmitted to the building body.

[0051] Further, the fixed end 431 of the hydraulic rod 430 can be fixedly installed with the sliding piece 610 on one side through welding, and the sliding piece 610 can be slidably connected with the guide rail 600 through sleeving. In this way, the hydraulic rod 430 can slide in the extension direction of the guide rail 600, effectively improving the working efficiency of the hydraulic mechanism 400.

[0052] Specifically, the fixed end 431 of the hydraulic rod 430 can be fixedly connected with the stiffening rib 310 of the node plate 300 through welding. In this way, the node plate 300 can be moved by the hydraulic rod 430 when the hydraulic rod 430 moves. The node plate 300 and the buckling-restrained energy-dissipation brace 500 are connected through a pin shaft. In this way, when the multiple energy-dissipation structure 10 vibrates, the hydraulic rod 430 can drive the buckling-restrained energy-dissipation brace 500 to translate within a certain range, thereby dissipating energy and weakening most of the energy brought by vibration, and further ensuring the stability of the building.

[0053] The movable end 432 of the hydraulic rod 430 can be provided in a boss structure. The movable end 432 of the hydraulic rod 430 can penetrate the opposite ends of the hydraulic cylinder 410 and the piston 420 inside the hydraulic cylinder 410 through sleeving connection. In this way, the hydraulic rod 430 can reciprocate relative to the hydraulic cylinder 410. The hydraulic rod 430 can be fixedly connected with the piston 420 through coaxial sleeving connection, and the fixed end 431 of the hydraulic rod 430 is fixedly connected with the stiffening rib 310 of the node plate 300. In this way, when the hydraulic rod 430 and the node plate 300 translate together, the node plate 300 can drive the piston 420 to translate in the same direction inside the hydraulic cylinder 410 through the hydraulic rod 430, so as to change the volumes of the first chamber 411 and the second chamber 412 inside the hydraulic cylinder 410. When the hydraulic rod 430 translates inside the hydraulic cylinder 410, the flow of hydraulic oil between the first chamber 411 and the second chamber 412 is compressed, so that the hydraulic oil can effectively absorb most of the energy generated by the building due to the earthquake, thereby ensuring the stability of the building.

[0054] During the installation of the hydraulic rod 430, a layer of appropriate special lubricant is evenly applied to the surface of the hydraulic rod 430, which can reduce the friction and wear of the hydraulic rod 430 when moving inside the hydraulic cylinder 410, and also helps to improve the sealing performance of the hydraulic cylinder 410. During the installation of the hydraulic rod 430 and the hydraulic cylinder 410, the axis of the hydraulic rod 430 should coincide with the axis of the hydraulic cylinder 410, so as to avoid damage to the hydraulic mechanism 400 or bending of the hydraulic rod 430 due to the inclination or collision of the hydraulic rod 430, thereby ensuring the safety and structural stability of the hydraulic mechanism 400.

[0055] Please continue to see Figure 5 , Figure 8 andFigure 9 As shown, according to another embodiment of the present invention, the hydraulic mechanism 400 further includes: a first limiter 440, the first limiter 440 is connected to the guide rail 600, and the first limiter 440 is spaced apart on the side of the hydraulic cylinder 410 away from the node plate 300, and the first limiter 440 is used to connect with the movable end 432 of the hydraulic rod 430 to limit the initial position of the hydraulic rod 430.

[0056] Specifically, the first stoppers 440 can be configured as rectangular stopper plates. There can be two pairs of first stoppers 440, which can be installed at intervals on the upper and lower inner sides of the guide rail 600 via welding, riveting, or bolting, in a symmetrical layout. The spacing between the first stoppers 440 can be adjusted to suit different hydraulic rods 430. This arrangement effectively improves the practicality of the hydraulic mechanism 400. The first stoppers 440 can be spaced apart on the side of the hydraulic cylinder 410 away from the gusset plate 300, thereby effectively defining the initial position of the hydraulic mechanism 400. The first stoppers 440 can be fixedly connected to the movable end 432 of the hydraulic rod 430 via a threaded connection, thereby limiting the forward movement of the hydraulic rod 430. Alternatively, the first stoppers 440 can be installed at intervals on the steps of the movable end 432 of the hydraulic rod 430 via a bolted connection, thereby limiting the movement of the hydraulic rod 430.

[0057] By providing two pairs of first stoppers 440, during normal building use or during minor earthquakes, the first stoppers 440 can restrict the initial position of the hydraulic rods 430, thereby ensuring the static stability of the entire multi-energy dissipation structure 10. It should be noted that the spacing between the first stoppers 440 can be adjusted based on the thickness of the boss at the movable end 432 of the hydraulic rod 430, thereby enhancing the flexibility of the hydraulic mechanism 400.

[0058] The initial position of the hydraulic mechanism 400 is the initial fixed position of the hydraulic rod 430 when the multiple energy dissipation structure 10 is installed.

[0059] Please continue to see Figure 5 、 Figure 6 、 Figures 8-10 As shown, according to an optional embodiment of the present invention, the hydraulic mechanism 400 also includes: a second limiter 450, the second limiter 450 is connected to the guide rail 600, and the second limiter 450 is spaced apart on the side of the first limiter 440 away from the hydraulic cylinder 410, and the second limiter 450 is used to abut against the movable end 432 of the hydraulic rod 430 to limit the hydraulic rod 430 from retreating.

[0060] Specifically, the second limiter 450 can include a first spring 451 and a limiting block 452, which can be configured as a triangular structure or a trapezoidal structure. One end of the first spring 451 can be fixedly connected to a right-angle surface of the limiting block 452 by welding. The second limiter 450 can also be arranged at a side of the first limiter 440 away from the hydraulic cylinder 410, and the limiting block 452 can be used to abut against the movable end 432 of the hydraulic rod 430, so as to limit the retraction of the hydraulic rod 430.

[0061] The second limiter 450 further includes a connecting block 453, one end of which can be fixedly connected to the first spring 451 by welding, and the other end of which can be fixedly installed with a second spring 454 by welding, and the other end of the second spring 454 can be fixedly installed with the guide rail 600 by welding, so as to facilitate the guide rail 600 to provide support for the second limiter 450. The connecting block 453 is provided with a first support 455 and a second support 456 at two sides thereof, and a bracket 457 is arranged at a central position of the connecting block 453, one end of the bracket 457 is fixedly connected to the first support 455, and the other end of the bracket 457 can abut against the second support 456 to limit the retracted position of the second limiter 450. When the initial position of the hydraulic mechanism 400 needs to be reset at the end of an earthquake, the user can manually press down the bracket 457, so that the bracket 457 abuts against the second support 456, at this time, under the compression of the second spring 454, the bracket 457 can drive the connecting block 453 to make the first spring 451 and the limiting block 452 reach the retracted position, at this time, the movable end 432 of the hydraulic rod 430 can smoothly pass through the second limiter 450; when the hydraulic mechanism 400 returns to the initial position, the user can manually unlock the abutment of the bracket 457 and the second support 456, at this time, the first spring 451 and the limiting block 452 can return to the initial limiting position.

[0062] The installation position of the second limiter 450 can be determined according to the travel range of the hydraulic cylinder 410 and the travel range of the buckling-restrained energy-dissipation support 500, and the user can select a suitable installation position of the second limiter 450 according to different application scenarios.

[0063] When the building bears a large amount of seismic energy, the hydraulic rod 430 breaks through the first limiter 440 and moves to the second limiter 450 by setting the second limiter 450, when the movable end 432 of the hydraulic rod 430 reaches the installation position of the second limiter 450, the hydraulic rod 430 can abut against the limiting block 452, with the movement of the movable end 432 of the hydraulic rod 430, the limiting block 452 will drive the first spring 451 to extrude and shrink, when the movable end 432 of the hydraulic cylinder 410 passes through the second limiter 450, the first spring 451 can drive the limiting block 452 to restore to the original state, at this time, the limiting block 452 can limit the retreat of the movable end 432 of the hydraulic rod 430. The second limiter 450 can convert part of the kinetic energy generated by the building in a strong earthquake into elastic potential energy, so as to ensure the stability of the building.

[0064] Please continue to see Figure 5 、 Figures 8-10 As shown in FIGS. 4 and 5, according to further embodiments of the present application, the hydraulic mechanism 400 further comprises: a third limiter 460, the third limiter 460 is connected with the guide rail 600, and the third limiter 460 is arranged at a side away from the first limiter 440 of the second limiter 450, the third limiter 460 is used for abutting against the movable end 432 of the hydraulic rod 430 to limit the termination position of the hydraulic rod 430.

[0065] Specifically, the third limiter 460 can be configured as a rectangular limiting block poured by concrete, the third limiter 460 can be fixedly connected with the guide rail 600 by means of bolt connection, and the third limiter 460 can be arranged at a side away from the first limiter 440 of the second limiter 450. In this way, the termination position of the hydraulic rod 430 can be determined. The other end of the third limiter 460 can be used for abutting against the movable end 432 of the hydraulic rod 430, when the hydraulic rod 430 passes through the second limiter 450 to reach the third limiter 460 in a strong earthquake, at this time, the movable end 432 of the hydraulic rod 430 can abut against the third limiter 460, so as to limit the termination position of the hydraulic rod 430.

[0066] The thickness of the third limiter 460 can be calculated and determined according to the movement distance of the hydraulic rod 430, and the third limiter 460 can be arranged at the stroke end of the hydraulic rod 430, so as to prevent the excessive displacement of the hydraulic rod 430 from causing damage to the multiple energy dissipation structure 10.

[0067] The termination position of the hydraulic rod 430 can be the stroke end position of the hydraulic rod 430.

[0068] Please continue to see Figure 2 and Figure 8As shown, in one embodiment of the present application, when the building is under the left shock of the strong earthquake, the movable end 432 of the hydraulic rod 430 can break through the first limiter 440 and move left through the second limiter 450 to reach the third limiter 460 and abut against the third limiter 460; at this time, the fixed end 431 of the hydraulic rod 430 can drive the node plate 300 to move left together, and the buckling-restrained energy-dissipation support 500 is hinged to the node plate 300, which can rotate counterclockwise and move left together with the node plate 300 under the strong earthquake until the hydraulic rod 430 abuts against the third limiter 460.

[0069] Please continue to see Figure 3 and Figure 9 As shown, in another embodiment of the present application, when the building is under the right shock of the strong earthquake, the movable end 432 of the hydraulic rod 430 can break through the first limiter 440 and move right through the second limiter 450 to reach the third limiter 460 and abut against the third limiter 460; at this time, the fixed end 431 of the hydraulic rod 430 can drive the node plate 300 to move right together, and the buckling-restrained energy-dissipation support 500 is hinged to the node plate 300, which can rotate clockwise and move right together with the node plate 300 under the earthquake energy until the hydraulic rod 430 abuts against the third limiter 460.

[0070] By setting the hydraulic mechanism 400, a multiple energy dissipation system can be formed, which can play its respective role under different earthquake energy. Under normal / small earthquake, the multiple energy dissipation structure 10 can rely on the lateral stiffness provided by the buckling-restrained energy-dissipation support 500 and the hydraulic mechanism 400 to jointly bear the force to maintain the stability of the building; as the earthquake energy level further increases, the multiple energy dissipation structure 10 can consume most of the earthquake energy through the flow of hydraulic oil inside the hydraulic cylinder 410 and the conversion of the structural system to realize the first energy dissipation of the multiple energy dissipation structure 10, and then through the setting of the first limiter 440, the second limiter 450 and the third limiter 460 and the deformation of the energy dissipation beam segment 210 to realize the second energy dissipation of the multiple energy dissipation structure 10, and finally through the flexibility of the material of the buckling-restrained energy-dissipation support 500 to realize the third energy dissipation of the multiple energy dissipation structure 10, so as to form a multiple energy dissipation system, which can effectively protect the safety of the building under strong earthquake.

[0071] Please continue to see Figure 5 , Figures 8-10 As shown, in one optional way of the present application, the hydraulic mechanism 400 further comprises an oil delivery assembly 470, which is in communication with the first chamber 411 and the second chamber 412 respectively, and is used for delivering the hydraulic oil from the first chamber 411 to the second chamber 412 or from the second chamber 412 to the first chamber 411.

[0072] Specifically, the oil delivery assembly 470 can be connected and communicated with the first chamber 411 and the second chamber 412 of the hydraulic cylinder 410, so as to facilitate the transmission of the hydraulic oil in the hydraulic mechanism 400. In an embodiment of the present application, the oil delivery assembly 470 can deliver the hydraulic oil in the hydraulic cylinder 410 from the first chamber 411 to the second chamber 412; in another embodiment of the present application, the oil delivery assembly 470 can deliver the hydraulic oil in the hydraulic cylinder 410 from the second chamber 412 to the first chamber 411.

[0073] Please continue to see Figure 10 As shown in the drawings, in some examples of the present application, the oil delivery assembly 470 includes: an oil pump 471; an oil pipe 472, the oil pipe 472 being communicated with the inlet and outlet of the oil pump 471; a valve 473, the oil pipe 472 being communicated with the first chamber 411 and the second chamber 412 through the valve 473.

[0074] Specifically, the oil pump 471 can be fixedly installed in the oil delivery circuit by means of bolt connection, and during the installation process, attention should be paid to the levelness and perpendicularity of the oil pump 471 to avoid vibration and noise of the oil pump 471 due to improper installation.

[0075] The number of the oil pipe 472 can be multiple, and the oil pipe 472 can connect the oil pump 471 and the first chamber 411 and the second chamber 412 of the hydraulic cylinder 410, so as to form a closed loop oil circuit for the first chamber 411 and the second chamber 412. During the installation process, the two ends of the oil pipe 472 can be respectively installed with pipe joints (not shown in the drawings), and the oil pipe 472 with the installed pipe joints can be connected to the oil outlet of the oil pump 471 at one end and to the oil inlet of the hydraulic cylinder 410 at the other end. In this way, the sealing performance of the oil circuit can be effectively improved, thereby improving the reliability of the oil delivery assembly 470.

[0076] The valve 473 can be configured as a hydraulic valve 473, and the valve 473 can be installed at the two ends of the oil pipe 472. In this way, the hydraulic valve 473 can accurately control the flow, pressure and direction of the hydraulic mechanism 400, thereby improving the safety and reliability of the oil circuit and reducing the maintenance cost and failure rate of the oil delivery assembly 470.

[0077] In a normal state, the valve 473 is in a closed state, and the hydraulic oil in the first chamber 411 and the second chamber 412 cannot be transmitted to each other through the oil path; when the strong earthquake ends, the user can open the valve 473, at which time the oil pump 471 starts to work. In an embodiment of the present application, the oil pump 471 can deliver the hydraulic oil in the first chamber 411 to the second chamber 412 through the oil pipe 472, the hydraulic rod 430 is reset, and the valve 473 is closed; in another embodiment of the present application, the oil pump 471 can deliver the hydraulic oil in the second chamber 412 to the first chamber 411 through the oil pipe 472, the hydraulic rod 430 is reset, and the valve 473 is closed. By arranging the oil delivery assembly 470, the hydraulic rod 430 can be quickly restored to the pre-earthquake state, so that the maintenance time and cost of the multiple energy dissipation structure 10 after the strong earthquake can be greatly reduced.

[0078] In addition, in the post-earthquake repair work, compared with the traditional energy dissipation mechanism, the multiple energy dissipation structure 10 is designed to dissipate energy three times, and the post-earthquake buckling energy dissipation support 500 is basically undamaged and can continue to be used, so that the repair cost of the multiple energy dissipation structure 10 can be greatly saved and the post-earthquake repair progress can be significantly shortened.

[0079] Please continue to refer to Figure 5 、 Figure 8 and Figure 9 , in some examples of the present application, the main beam 200 includes: energy dissipation beam segments 210 and non-energy dissipation beam segments 220 connected to each other, and the energy dissipation beam segment 210 has a plurality of transversely arranged stiffening ribs 230 for increasing the stiffness of the energy dissipation beam segment 210.

[0080] Specifically, when the hydraulic rod 430 abuts against the second limiter 450, the buckling energy dissipation support 500 rotates and translates a certain distance on the main beam 200, the main beam 200 segments within the translation range of the buckling energy dissipation support 500 are energy dissipation beam segments 210, and the main beam 200 segments outside the translation range of the buckling energy dissipation support 500 are non-energy dissipation beam segments 220. The energy dissipation beam segment 210 can absorb and dissipate the energy caused by the earthquake action of the building through its own deformation, so as to reduce the damage of the multiple energy dissipation structure 10 to ensure the safety of the building. The length of the energy dissipation beam segment 210 can be determined by calculation, and it should be noted that the energy dissipation beam segment 210 should not be greater than 1.6Mlp / Vl specified in the specification.

[0081] The transverse stiffening ribs 230 can be uniformly arranged in the length range of the energy dissipation beam segment 210, and the transverse stiffening ribs 230 can be configured as a one-letter steel plate. The transverse stiffening ribs 230 can be connected to the upper and lower flanges (not shown in the figure) and the web (not shown in the figure) of the main beam 200 by welding. In this way, the rigidity and local stability of the energy dissipation beam segment 210 can be ensured, so that the main beam 200 can effectively and continuously dissipate energy without instability. The spacing of the transverse stiffening ribs 230 can be determined according to calculation, and users can select different transverse stiffening rib 230 spacings according to different application scenarios.

[0082] Please continue to see Figures 1-4 As shown in some examples of the present application, the multiple energy dissipation structure 10 further comprises a one-letter center support 700, and the opposite ends of the one-letter center support 700 are fixedly connected to the node plates 300, respectively.

[0083] Specifically, one end of the one-letter center support 700 can be fixedly connected to the node plate 300 by welding, and the other end of the one-letter center support 700 can also be fixedly connected to the diagonally opposite node plate 300 by welding. In this way, the one-letter center support 700 can provide stable support for the column 100. It should be noted that the installation position of the one-letter center support 700 should be located at three or more layers at the bottom of the multiple energy dissipation structure 10. In this way, during a strong earthquake, the column 100, the main beam 200 and the buckling-restrained energy dissipation support 500 at the bottom two layers can be converted from a frame-center support structure to a frame-bottom eccentric support structure, while the column 100, the main beam 200 and the one-letter center support 700 at the upper part can remain as a frame-center support structure, so that the multiple energy dissipation structure 10 can achieve multiple energy dissipation and simultaneously reduce the manufacturing cost of the multiple energy dissipation structure 10.

[0084] Other configurations of the multiple energy dissipation structure 10 capable of achieving dynamic deformation under a strong earthquake according to the embodiments of the present application, such as welding, pipe joints, oil lines, etc., and operations are known to those skilled in the art, and will not be described in detail here.
