Title: Strength and Ductility of Mechanically Spliced Bars
Appears on pages(s):
Abstract:Mechanical couplers are used in Australia to splice together hot-rolled, Class N reinforcing bars. As a general principle, couplers must have sufficient strength to enable the spliced bars to elongate sufficiently while approaching ultimate load. If a splice forms a weak, rigid link, with its failure load significantly less than that of either of the attached bars, then it can be deduced that the overall response of the spliced bars will be brittle. It follows that the spliced bars would then not satisfy the minimum ductility requirements for reinforcing bars specified in the new joint Australian/New Zealand Standard AS/NZS 4671, "Steel Reinforcing Materials".
