Abstract

3D-printed concrete is revolutionizing the construction industry through its mold-free manufacturing and high design flexibility. However, its performance variability-caused by factors like manufacturing processes, material properties, and environmental conditions-often leads to structural weaknesses, anisotropic behavior, and unconventional failure modes. While existing research employs discrete medium simulations, quantifying the impact of multi-source variability on structural reliability remains a critical challenge. To address this, this study establishes an analytical framework of "multi-source etiology-reliability impact," aiming to uncover underlying mechanisms. The findings will provide theoretical foundations for developing probabilistic design and code systems for 3D-printed concrete structures.

Keywords: 3D Printed Concrete; Multi-source Genesis; Discreteness; Reliability.
