Background The assembled steel structure house has the advantages of high construction speed, controllable component quality, environment friendliness and the like, and is an important direction of building industrialization development. In an assembled steel structure, the performance of a beam column connection node is directly related to the bearing capacity, rigidity and shock resistance of the whole structure. Traditional beam column connected nodes mainly adopt welding or high strength bolt connection mode. The traditional assembled steel structure beam column connection mainly adopts rigid connection modes such as welding or high-strength bolt connection and the like. These methods, while capable of providing adequate stiffness and strength, suffer from the following significant drawbacks: The seismic performance is insufficient, namely stress concentration is easy to generate in the rigid connection under the seismic action, so that brittle failure occurs in the node area, the energy consumption capability is limited, and the seismic energy is difficult to effectively dissipate. The damage after earthquake is irreversible, namely once the node is plastically deformed or destroyed in the earthquake, the integral structure is often caused to generate unrecoverable residual deformation, the repair is difficult and the cost is high, and even the integral replacement is needed. The construction is complex, the fault tolerance is poor, the field welding quality is greatly influenced by the environment and the technical level of workers, the high-strength bolt connection has extremely high requirements on the component processing and hole position centering precision, and the field installation is extremely difficult due to the deformation in the long-distance transportation and hoisting process. The traditional node design focuses on bearing and force transmission, lacks a targeted energy consumption mechanism and an automatic reset function after earthquake, and is difficult to meet the requirements of the modern building on earthquake resistance toughness and quick recovery and use functions. The high-strength bolt connection is convenient to install, but has limited energy consumption capability, and brittle failure is easy to occur under the action of an earthquake. Some node designs with energy consumption devices in recent years are often complex in structure, high in installation accuracy requirement, unfavorable for rapid construction and difficult in post-earthquake repair. Therefore, development of an assembled steel structure connecting node and a construction method which can ensure connection reliability and earthquake resistance, realize quick installation and facilitate post-earthquake repair is needed.
