Abstract
This paper describes a dynamic analysis of a floating bridge across Lake Okanagan at Kelowna, British Columbia, Canada. The structure is a replacement for an existing floating bridge that was opened to traffic in 1958. The floating section of the proposed new bridge consists of continuous concrete pontoons with a total length of 697 m. Due to the exposure of the bridge to wind generated waves and the large horizontal dimensions of the structure, a short-crested wave field was used to model the correlation of wave forces along the structure length. Numerical wave hindcasting was conducted to determine the design wave conditions, including the effects of directional spreading. A two-dimensional wave diffraction numerical model was used to calculate the frequency dependent hydrodynamic coefficients (added masses, damping and exciting forces) used in the dynamic analysis. The response of the bridge to wind and wave loads was evaluated in the frequency domain using a commercial finite element structural model. The response parameters of interest included the motions of the bridge, the anchor cable tensions and the six sectional forces in the pontoons (two bending moments, torque, two shears and an axial load).

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
