TRB’s National Cooperative Highway Research Program (NCHRP) Report 603: Transfer, Development, and Splice Length for Strand/Reinforcement in High-Strength Concrete explores recommended revisions to the American Association of State Highway and Transportation Officials Load and Resistance Factor Design (LRFD) Bridge Design Specifications, which are designed to extend the applicability of the transfer, development, and splice length provisions for prestressed and non-prestressed concrete members to concrete strengths greater than 10 ksi.
