Defining Structurally Acceptable Properties of High-Strength Steel Bars through Material and Column Testing

Research purpose

The proposed study will explore critical material and structural behaviors at the boundaries of high-strength steel properties that can currently be achieved. Key steel properties that will be explored are: 1) the tensile-to-yield strength ratio (T/Y ratio), 2) the ultimate or uniform elongation, and 3) the low-cycle fatigue performance. Material and structural tests on concrete columns will be conducted to compare behaviors at the high and low ends of the steel properties in production. Such tests will provide much needed experimental evidence to define structurally acceptable properties for steel mills to target in production and the research community to use in structural testing.
