[0002] Modular construction stands out for its advantages, including fast construction, minimal environmental impact, low cost, and large-scale production. As a new building structure system, modular construction uses prefabricated units, with each module manufactured in a factory. With its low-carbon, environmentally friendly, energy-efficient, cost-effective, and recyclable advantages, modular construction is becoming a new trend in the construction industry and is gaining widespread adoption worldwide. Each modular unit is connected through its nodes, forming the entire modular structure. Therefore, the connection nodes are crucial.
[0003] At present, domestic and foreign scholars mainly focus on the seismic performance of the connection nodes of modular structures, and have done less research on the vertical collapse performance of the nodes. If there are no reliable connection nodes, the structure is likely to collapse when it is hit by a disaster. Therefore, the research on connection nodes needs to be further deepened. The current modular connection nodes also have many shortcomings, such as: (1) the node design is complex and the number of components is large and cumbersome; (2) the strength between modular connection nodes is insufficient; (3) modular nodes cannot be disassembled and recycled.
