Experimental investigation of ribbing pattern effect on the bonding qualities of water jet cut steel reinforcement

Abstract With the rise of interest in digital fabrication reinforced concrete structures, a great number structural designs that depart from standard prismatic shapes are being suggested. This has prompted an exploration steel reinforcement strategies alternative to classical deformed or “ribbed” rebars. One such is cut internal plates using waterjet cutting machine. Advantages automated include high precision and accuracy, minimal expense for increasing complexity (2D) layouts. However, it not known how application ribbing patterns along edge reinforcing bars affects steel–concrete bond. work conducts experimental pullout tests waterjet-cut plate with three different compares bond strength equivalent classic Two tested geometries averaged within 90–91% pull-out force conventional rebar, demonstrating viability this method.
