To optimize the structure of these warehouses and reduce the amount of on-site wet work, this study proposed a new prefabricated SRC (steel-reinforced concrete) beam-column-slab joint connection for MGWs. Three new SRC spatial joint specimens were designed and tested under cyclic loading to investigate their performance under different grain storage conditions. The results showed that the hysteresis curves of the specimens were similar across all conditions, with failure modes primarily characterized by plastic hinge formation at the beam ends. As the grain storage amount increased, significant strain accumulation occurred in the reinforcement and steel sections at both the joint and beam ends, leading to evidently earlier yielding. A finite element model of the specimens was established using Abaqus for parametric analysis, which showed that grain load significantly affected the bolt tension force. Additionally, based on multiple SRC beam-column joint seismic performance test datasets and the mechanical properties of SRC structures, a Park-Ang modified damage model for SRC beam-column joints was proposed. The reliability of the newly introduced combination coefficient was validated, demonstrating that the proposed damage model could effectively predict joint damage.
