In this paper, when the core tube structure of the fabricated frame core tube is thin and the horizontal anchorage length of the longitudinal reinforcement on the upper part of the beam is insufficient, when the beam-wall is connected by a sleeve, the seismic performance test of the nodes with different mechanical anchoring measures is carried out. The seismic performance of the anchored reinforced fabricated beam-wall out-of-plane connection node is studied by considering factors such as wall top axial compression, constraints, etc., under the same reinforcement ratio, one cast-in-place specimen and two are prefabricated with different anchoring measures. The effects of different anchoring measures on the energy dissipation capacity, stiffness, ductility and ultimate flexural capacity of the fabricated beam-wall joint under the condition of low-cycle reciprocating load applied to the beam end are studied. The research results show that the anchoring performance of the fabricated specimens with anchor plate measures for anchoring reinforcement has been greatly improved. When the bearing capacity meets the requirements, the stiffness and ductility are also significantly improved compared with other specimens. When the load is controlled, the plastic hinge is formed at the joint of the beam end, and the anti-side movement ability is obviously better than the 90° hook anchoring method. It fully shows that when the horizontal anchoring length is insufficient, the anchoring strengthening measures can improve the force performance of the nodes and avoid the occurrence of pull-off failure.
