Abstract
In places where deicing salts are used to keep roads free of ice, the bridge components most prone to corrosion are concrete deck slabs, which can be made corrosion-free by replacing the steel reinforcement by bars made of fibre reinforced polymer (FRP). Recent experimental investigation has shown that only the transverse bars at the bottom of the deck slab confine the slab for full arching action. The rest of the reinforcement in the two assemblies only controls the widths of environmental and fatigue-induced cracks. An experimental fatigue study on full-scale models of deck slabs showed that slabs with steel bars have the poorest fatigue resistance and slabs with glass fibre reinforced polymer (GFRP) bars the best. ISIS Canada conducted field studies in 2005 to show that the GFRP is not attacked by alkaline reaction in concrete. Because of this finding the Canadian Bridge Highway Bridge Design Code (CSA S06–06) permits GFRP as a primary reinforcement.

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
