Assessment of Flexure Failure Models Using Loads Measured on the Conical Piers of the Confederation Bridge During 1998–2008
Bibliographic record
Abstract
The Confederation Bridge spans across the Northumberland Strait in Eastern Canada connecting Prince Edward Island to mainland Canada through New Brunswick. Due to the presence of ice during each winter, the bridge piers are subjected to ice loads. A comprehensive permanent monitoring program has been implemented to observe and measure the ice–structure interaction events at two piers since the start of the bridge operations in 1998. This study uses the derived ice loads on one pier, and the associated event attributes for 100 selected events. Flexural failure models are used to determine theoretical loads of the selected interaction events. It is found that the weight of the total ice rubble pile and the physical and mechanical properties of the ice sheet are the dominant parameters affecting the ice load exerted on the conical structure. A semi-empirical correlation is developed to relate the ice load with those parameters for the Confederation Bridge.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
