Abstract
The expansion of highway systems increased the need to provide corrosion-free reinforced concrete components for highway bridges. An extensive research program to investigate the behaviour of two types of concrete bridge barriers, PL-2 and PL-3, reinforced with glass fiber reinforced polymer (FRP) bars has been going during the last four years at the Universite de Sherbrooke (Sherbrooke, Quebec) in collaboration with the Ministry of Transportation of Quebec (MTQ). A new corrosion-free connection between the barrier wall and the slab using GFRP bent bars was investigated. A total of 8 full-scale 10-m long barrier prototypes were constructed and tested in the field under impact load.. The tests included 4 PL-2 and 4 PL-3 prototypes. For each type of barriers, two prototypes were reinforced with GFRP sand-coated bars and the other two were reinforced with steel bars. Pendulum crash tests using a 3.0-ton pear-shaped iron ball were performed under the same conditions for each type of barriers. The behaviour of the barriers was evaluated in terms of cracking pattern, crack width, and strains in reinforcing bars.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
