In order to study the performance of the anchor-connected shear wall under different lap parameters, ABAQUS was used to establish its analysis model. The C3D8R unit and T3D2 unit were used to model the concrete and steel bars respectively, and the steel bars were embedded into the concrete by embedding. Through the finite element analysis calculation and comparison with the test results, the applicability of the numerical analysis model is verified. On this basis, the structural skeleton under low-cycle repeated load tests is studied by changing the parameters of the connecting steel bar diameter, anchor length, and other parameters. Changes in curves, stiffness degradation curves, and energy dissipation capabilities.
