These specimens were extracted from two 60-year-old bridges in Abilene, Texas as part of an IAC project titled Structural Evaluation and Testing of Damaged RC Bent Caps.
The project aimed to:
- Assess existing shear distress in deteriorated reinforced concrete
- Explore retrofit strategies using fiber-reinforced polymer (FRP) and steel jackets
- Conduct full-scale testing at FSEL
The findings were used internally at TxDOT and likely shared at a fib (International Federation for Structural Concrete) symposium.
