Abstract: As an important support for the transformation of building industrialization, 3D printed concrete masonry (3DPCM) has insufficient research on the shear performance of structures and lacks structural design theory, which restricts the large-scale application of 3D printed concrete technology. To investigate the shear performance and influencing factors of 3DPCM, two types of 3DPCM with inclined ribbed cavity configurations were designed, and their failure modes and shear strength under shear load were analyzed. A proportional finite element model incorporating Cohesive elements was established to systematically explore the effects of key parameters, including material strength, cavity configurations, and interlayer bond strength on shear performance of 3DPCM. The results demonstrate that the 3DPCM of the two cavity configurations primarily exhibit double-shear failure, and an increase in the number of inclined ribs significantly enhances shear strength.Numerical simulation analysis shows that the interlayer bond strength has a significant impact on the shear performance and shows a positive correlation. The more evenly the inclined ribs are distributed in the cavity configurations and the larger the shear cross-section area is, the higher the shear strength will be. These research results can provide theoretical basis for the design of 3D printed concrete structures.
