Overview

Experimental campaign tests structural performance of a new reinforced 3DCP system, suggesting enhanced design guidelines.

Key Points

  • To analyze the structural behavior of a new reinforced 3D concrete printing technology and its effectiveness.
  • Conducted material characterization and pullout tests to assess bond-slip behavior between reinforcement and concrete.
  • Performed full-scale four-point bending tests on both traditional 3DCP and the newly reinforced R3DCP beams.
  • Developed a three-stage modeling approach incorporating discrete pin reinforcements for enhanced numerical analysis.
  • The experiments showed significant improvement in structural performance of R3DCP beams compared to traditional 3DCP beams.
  • Bond-slip tests revealed strong adhesion between pin reinforcements and printed material, indicating effective reinforcement.
  • Numerical simulations closely matched experimental data, confirming the proposed model's accuracy for future design applications.
