Abstract
This research focuses on developing and measuring the mechanical behavior of ultrahigh-performance fiber-reinforced concrete (UHPFRC), transverse, field-cast connections between precast bridge deck elements. The connections had a closed shape, exposed aggregates, and lap splice length of 10 bar diameters (db). Three slab designs were considered: high-performance concrete (HPC), high- performance fiber-reinforced concrete (HPFRC), and hybrid HPFRC and UHPFRC. The first set of specimens was subjected to quasi-static loads up to failure, while the second set was subjected to cyclic fatigue loads prior to quasi-static loading to failure. Experimental results showed that all precast bridge decks with UHPFRC connections presented the same stiffness and ultimate strength as equivalent cast-in-place (CIP) slabs. Finite-elements models reproduced experimental results accurately and were used for predicting the mechanical behavior of continuous bridge slabs. Parametric studies demonstrated that, under various loading conditions, transverse UHPFRC field-cast connections do not modify the stiffness, ultimate strength, and failure mode of a slab differently than the equivalent CIP systems.

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
