Abstract:

This project assessed the use of ASTM A706 Grade 80 reinforcing bars in reinforced concrete columns. ; Grade 80 is not currently allowed in reinforced concrete columns due to lack of information on the ; material characteristics and column performance. Six half-scale, circular columns were tested: three ; constructed with Grade 60 reinforcement and three constructed with Grade 80 reinforcement. Designs ; followed standard design methodologies used by State Highway Agencies (including AASHTO). ; Results indicate that columns constructed with Grade 80 reinforcement performed similar to columns ; constructed with conventional ASTM A706 Grade 60 reinforcement. Computational modeling was ; performed using OpenSees for all six columns. Results indicate that the columns constructed with ; Grade 80 reinforcement achieved similar resistance and displacement and curvature ductility values ; when compared with the reference columns constructed with Grade 60 reinforcement. The columns ; constructed with Grade 60 reinforcement showed larger hysteretic energy dissipation than the columns ; constructed with Grade 80 reinforcement.
