Title: Behavior of Straight and T-Headed ASTM A1035/A1035M Bar Splices in Flexural Members
Author(s): Sergio F. Breña, Jeffrey Messier, and Sean W. Peterfreund
Publication: Structural Journal

Keywords: high-strength reinforcement; lap splices; T-headed reinforcement
Abstract:Interest has increased in recent years in the use of high-strength reinforcement in structural concrete members. This paper discusses the behavior of flexural elements that contain coupled or lapped high-strength reinforcement conforming to ASTM A1035/A1035M. Behavior of elements containing couplers or spliced straight and T-headed bars are included, adding to the number of test results available for broadening the application of high-strength reinforcement in structural concrete. In addition to general observations on the behavior of specimens tested in this experimental program, information on measured strain distributions along the splices are provided from which key force-transfer mechanisms between bars are identified. The benefits of having transverse reinforcement within the splice of T-headed are highlighted.
