Starting from the research of fabricated concrete frame structure system, the bolt-end plate connection applied in the steel structure and the combined structure is extended into the reinforced concrete structure to form a frame structure with a high-strength bolt-end plate connection. The quasi-static test was carried out. The test results show that the nodes exhibit good ductility and energy dissipation. In order to further explore the seismic performance of this type of structure, according to the experimental fitting method and the “fixed point pointing” law, on the basis of the skeleton curve’ s dimensionless treatment, the resilience model of this kind of nodes is established, and compared with the experimental results, the two agree well, which can be provides a certain reference for elasto-plastic seismic response analysis of this type of structure.
