Title: Lapped Splices in Reinforced Concrete Slabs–Experimental Review of Current & Proposed Code Revisions
Appears on pages(s):
Abstract:The proposed amendments outlined in DR 05252 for the calculation of lapped splice
lengths for reinforcing bars in slabs have generated debate in the design community. In this paper, the results of an initial investigation into the adequacy of lapped splice lengths are reported. The specimens were tested in direct tension and lap lengths conforming to the current AS3600-2001 (CIA
handbook interpretation), AS3600-2001 (Gilbert interpretation), and DR 05252 were investigated. These initial test results confirm that the current provisions in AS3600-2001, as commonly interpreted, may lead to non-ductile failure of lapped splices. Adoption of the proposed changes outlined in DR05252 led to ductile failure of the lapped splices in the test specimens.
