In order to study the influence of the horizontal steel bar connection method on the seismic performance of the composite shear wall joints, this paper designed two types of composite joints, which were horizontal reinforcements with or without embedded column. Under cyclic loading, a total of four specimens of two types of joints were subjected to seismic tests. By studying the deformation, failure characteristics, hysteretic characteristics, ductility and energy dissipation capabilities of the composite shear wall node, the seismic performance of the composite shear wall connection node is analysed. Through comparative analysis of bearing and deformation, ductility, energy consumption and other indicators, it is obtained that the cracking, yielding and ultimate load of the joints of horizontal steel bars are increased by 2.42%, 10.84% and 9.25% respectively; the ductility coefficient is increased by 10.26%; the energy consumption coefficient has been increased by 8.70%. It can be seen that the overall seismic performance of the joint specimens can be effectively improved by reasonable reinforcement and connecting the shear wall nodes.
