Abstract

The structural behaviour of load-bearing 3D-printed concrete (3DPC) elements has gained increasing attention. However, the lack of established mechanical models and design bases for 3DPC elements, whose design is not covered by current standards, leads to the need for structural testing to evaluate their structural behaviour. This paper focuses on the results of a pilot testing campaign of five direct tensile tests on reinforced 3DPC ties, each incorporating a longitudinal reinforcing bar embedded in grout and enclosed by a 3DPC shell. The experimental results illustrate the tensile performance and highlight the potential of 3DPC as a structural material, with the aim of supporting the development of a reliable testing methodology and laying the ground for mechanically consistent models for the structural analysis and design of 3DPC elements in future research.
