Abstract
<p>The paper presents the results of an experimental and analytical research program aimed at developing an innovative seismic strengthening technique using Ultra‐high Performance Fibre Reinforced Concrete (UHPFRC) cover applied to existing bridge piers with deficient reinforcement detailing. Experimental results on full‐scale rectangular bridge pier specimens with cross‐sectional aspect ratios of 4:1 and 2:1 subjected to weak or strong axis bending showed that the exceptional mechanical properties of UHPFRC allow eliminating concrete failure modes such as splitting cracks, spalling and crushing, thereby allowing transferring lapped bar forces through the surrounding UHPFRC, as well as failure modes associated with inadequate reinforcement detailing. Refined 3D nonlinear finite element models were developed to provide a numerical tool for evaluating the performance the strengthening technique.</p>

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
