Seismic Behavior of High Strength Reinforcing Steel at Low Temperatures

This research is to study the impact of low temperatures on the seismic behavior of columns reinforced with A706 Grade 80 and 100 steel. This will be accomplished through the use of the Buckled Bar Tension test and large scale column tests, both conducted at low temperatures at the NC State Constructed Facilities Laboratory, as well as computational modelling of columns (and bridge systems) using stress-strain models and section hysteretic behavior observed during the conduct of the experiments. This project includes lab testing, a literature review, cost optimization, data analysis, performance analysis, recommendations for DOT, and a final report.
