Abstract
<p>In the last years, extreme climate events as thunderstorm and downburst are becoming increasingly frequent and widespread. These phenomena could significantly impact on the dynamic response of super long-span bridges since they are typically characterized by a sudden variations of the mean wind speed combined with large vertical angles of attack. This contingency is considered an interesting opportunity for the IABSE Task group 3.1, involved for the last 5 years in the benchmark of the software for the computation of the bridge response to the turbulent wind, to extend the applicability of the consolidated numerical procedures to a case of study characterized by a non-synoptic wind. To reach this purpose, taking as a target the full-scale data measured on the Gjemnessund Bridge during two different incoming wind conditions, a comparison with numerical results is proposed. Specifically, the working group has defined two steps of increasing complexity. The first, given the same input data to the participants, consists of a preliminary numerical benchmark while, the second, concerns the comparison between the outcomes and the dynamic response of the real bridge. In this paper, the results of the wind tunnel tests, performed to measure all the aerodynamic coefficients required for numerically simulating the bridge response, are reported. Finally, the first step is presented and some preliminary outcomes are shown.</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
