[0053] The connection device of the utility model has the characteristics of clear force transmission mode, high reliability, easy transportation, easy control of construction quality, and node appearance that does not affect the beauty of the building. It can be widely used in beam-column connections of various steel structure systems.

[0054] All components of the utility model can be mass-produced in factories and transported to construction sites for installation and overlap, which can greatly reduce the workload of on-site welding, save a lot of human resources, increase construction efficiency, and save construction period; the assembled beam-column node of the utility model has good force-bearing performance. When the components are subjected to force, plastic hinges can be formed on the H-shaped steel beams. The flange plates and the bolts thereon bear part of the force from the nodes to reduce the bearing pressure of the bolts between the square tube columns and the outer sleeves, which can effectively improve the deformation capacity and bearing capacity of the nodes. At the same time, a low-yield point arc-shaped steel plate is provided, which can first enter yield and continuously consume energy when an earthquake occurs, so that the earthquake damage is concentrated on the arc-shaped steel plate, thereby protecting the entire device and enhancing the seismic resistance of the nodes.

[0055] It should be noted that setting low yield point curved steel plates is an effective seismic design strategy, especially in earthquake-prone areas. This design can significantly improve the seismic performance of building structures. The following is a detailed explanation of this design method:

[0056] Characteristics of low yield point materials: Low yield point materials have low yield strength and good ductility, which means that when subjected to external forces, they can begin to undergo plastic deformation under small stresses and absorb and dissipate a large amount of energy in the process. This characteristic enables low yield point steel plates to enter the yield state first during an earthquake, thereby effectively reducing the stress on the main structure.

[0057] Energy dissipation mechanism under earthquake action: When an earthquake occurs, due to the low yield strength of the low yield point curved steel plate, it will first enter the plastic deformation stage and absorb and dissipate the earthquake energy through plastic deformation. In this way, the damage caused by the earthquake is mainly concentrated on the curved steel plate, thus protecting the main structure from serious damage.

[0058] Strengthening the seismic performance of the nodes: By setting low-yield arc-shaped steel plates, the seismic performance of the nodes has been significantly strengthened. In an earthquake, the steel plates can absorb a large amount of energy, reduce the stress concentration at the nodes, and thus reduce the risk of node damage.

[0059] Comprehensive benefits: This design method not only improves the seismic performance of the structure, but also helps reduce the cost of repairs after an earthquake. Since the damage is mainly concentrated on the curved steel plate, it is relatively easy to replace or repair the steel plate without causing much impact on the overall structure.

[0060] In conclusion, setting low yield point curved steel plates is an effective seismic design strategy, which protects the entire device from serious damage by utilizing the properties of materials to absorb and dissipate seismic energy. This design method has broad application prospects in the field of earthquake engineering.
