AB  - Prefabricated buildings have developed rapidly due to their advantages in energy efficiency, environmental protection, and high construction efficiency, which have greatly promoted the advancements of connection technology and the mechanical properties of prefabricated hollow panels. This study proposes a new optimization scheme for prefabricated wall structures using transversely arranged prefabricated hollow plates and develops a new joint connection. First, the constitutive relations are experimentally validated to establish an accurate finite element analysis model; Then the equal-size specimens are compared with the control specimens without node connections; Finally, the effects of axial compression ratio, aspect ratio, and channel steel plate thickness on the seismic performance of the wall are discussed. The experimental results demonstrate that this joint connection can significantly enhance the mechanical performance of walls. The influence of the axial compression ratio and the aspect ratio on the seismic performance of walls is significant, necessitating strict compliance with code specifications. Excessive thickness of the steel plate may negatively impact the structural bearing capacity, providing a technical reference for further investigation.
