Performance of High-Strength Steel Reinforcement in Shear Friction Applications

The objective of this research is to evaluate and define the performance of A706 Grade 80, American Society for Testing and Materials (ASTM) A615 Grade 100, and ASTM A1035 (120 ksi) reinforcing steel performance in shear friction applications. Understanding the performance is crucial for evaluating and assessing the applicability of the current design equations for reinforced concrete (RC) structures using high strength steel (HSS) reinforcement. If successful, the research will provide necessary data for supporting a recent working agenda item (WAI) presented to the American Association of State Highway and Transportation Officials-T10 (AASHTO)-T10 committee by Oregon Department of Transportation (ODOT).
