In order to reveal the regulation law of cross-sectional configuration on the seismic performance of 3D printed concrete walls, and to make up for the shortcomings of existing research that mainly focuses on monotonic loading and rare analysis of seismic differences under reciprocating loads, this study adopts a concrete damage plasticity model and a cohesive interface model to design three typical cross-sectional walls: hollow, inclined rib, and vertical rib. Two axial compression ratios of 0.1 and 0.2 are set, and displacement controlled reciprocating loading is used to compare and analyze the displacement ductility, stiffness degradation, energy dissipation capacity, skeleton curve, and failure mode of the wall. The experimental results show that under the same axial compression ratio, the ductility of ribbed walls is significantly better than that of hollow walls. When the axial compression ratio is 0.1, the ductility coefficients of vertical and inclined ribbed walls are increased by 19% and 11% respectively compared to hollow walls; When the axial compression ratio increases from 0.1 to 0.2, the ductility coefficient of the three types of walls decreases by 5% to 10%, the stiffness degradation rate slows down, the energy dissipation capacity improves, and the ultimate bearing capacity increases but the ultimate displacement decreases; The degree of damage decreases from high to low as follows: hollow wall>inclined rib wall>vertical rib wall. Research has shown that vertical rib sections have both printability and excellent seismic performance, and changes in axial compression ratio do not alter their impact on ductility.
