Welded Deformed Wire Reinforcement Development Length and Lap Splice Per ACI 318-19
Date: September 2021
Welded deformed wire reinforcement (WDWR) is comprised of an orthogonal arrangement of machine-welded deformed wires, with wire sizes between D4.0 and D31.0. The wires themselves have surface deformations along their entire circumferential length. These wire deformations conform to the geometrical requirements established by ASTM A1064 and are capable of developing bond through bearing and friction between deformed wire surface and surrounding hardened concrete.
