GFRP-steel hybrid reinforced concrete bridge deck slabs in Quebec, Canada
Bibliographic record
Abstract
In GFRP-Steel hybrid reinforced concrete (RC) bridge deck slabs, the non-corrodible glass fiber-reinforced polymer (GFRP) bars are used in the top reinforcement mat and the steel bars are used in the bottom reinforcement mat. This technique is being used by the Ministry of Transportation of Quebec (MTQ) in collaboration with the University of Sherbrooke (UdeS) as it is expected to yield cost-effective and durable concrete bridge decks. This paper highlights the recent hybrid-reinforced bridge deck applications on the extension of Hwy 410 in Sherbrooke (Quebec, Canada). So far, the project included four hybrid bridges where three of them were single-span simply supported bridges (P-15501, P-15502N, and P-15502S) and the fourth one was three-span continuously supported bridge (P-15604). In addition, this paper presents and discusses the typical results of the live load field tests conducted on the P-15502S bridge using three calibrated trucks.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
