Investigating the Seam Effect on Structural Failure of Additively Constructed Pipe Culverts
Description
Additive construction, specifically 3D Concrete Printing (3DCP), offers potential benefits for pipe culvert construction by reducing labor, material waste, and costs. However, concerns remain about the structural integrity of 3DCP pipes, particularly due to the seam effect stemming from layer-by-layer printing. This study tested six 3DCP pipes to assess how seam placement affects cracking patterns and load-bearing capacity. Pipes with seams aligned within 20 degrees of critical location failed at the seam while pipes situated further away failed at the typical region.
