Abstract

3D printed concrete technology is developing rapidly but faces challenges in large-scale applications because the seismic performance of these structures is unclear. This study investigated the seismic performance of 3D printed reinforced concrete wall (3DPRCW) under quasistatic cyclic loading and developed a finite element model based on the parameters of interfacial pore defects to conduct parametric analyses. The results showed that interlayer interfaces significantly affected crack initiation and propagation, resulting in X-shaped through-cracks and shear compression failure. The ultimate load-bearing capacity of the rectangular cross-section was 17.8 % higher than that of the corrugated cross-section. The load-bearing capacity of the 3DPRCW was linearly positively correlated with the axial compression ratio in the range of 0.1–0.3, whereas increasing the core column’s concrete strength had no significant effect. The failure mechanism was analyzed based on interfacial pore defects. These findings provide critical insights into seismic design methodologies for 3DPRCW structures.
