Abstract
Severe cracking was observed on the flexural tension face of a reinforced concrete hammerhead bridge pier cap. Determining the cause and severity of the damage was complicated by the geometry of the piers, which influenced the strut-and-tie mechanism. A tapered end cap raised questions about the development of the tension reinforcement in the chord, while a hexagonal pier column meant that the effective area of the compressive strut was uncertain. Depending on the assumptions made, widely different estimates of the ultimate capacity were reached by traditional calculation methods. Therefore, to accurately assess the safety of the bridge piers, a series of analyses were performed using VecTor2 – a nonlinear finite element analysis program (NLFEA) developed at the University of Toronto. A parametric study was conducted by varying the effective width of the piers and the amount of reinforcement engaged, and the factored strength of the pier was obtained using a novel procedure. This paper concludes that using 2-D NLFEA in a discerning manner allows engineers to understand complex 3-D situations.

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
