Development of Tentative Specification for High-Strength Steel Reinforcing Bar

Development of Tentative Specification for High-Strength Steel Reinforcing Bar

The CPF is presently sponsoring Project ATC-115: Development of a Roadmap on Use of High-Strength Reinforcement in Reinforced Concrete Design, which is being carried out by the Applied Technology Council (ATC). At the same time, the Concrete Reinforcing Steel Institute (CRSI) has formed a task group that is seeking to establish a possible new manufacturing specification for high-strength reinforcement with improved ductility. These two efforts are only loosely coordinated, with a CRSI staff member appointed to the Project Review Panel of the ATC-115 project.

CPF would like to strengthen the interaction between the ATC-115 project, the CRSI task group efforts, and relevant research projects being funded by CPF. To that end, CPF is asking WJE to provide professional structural engineering research services to develop tentative requirements for tensile properties of a high-strength, ductile reinforcing bar, and to facilitate coordination among the various involved entities, such as ATC, CRSI, and the CPF-funded researchers. The development effort is to include participation in selected web conferences and in-person meetings related to the ATC-115 project, the CRSI task group efforts, and the CPF-funded research.
