Abstract
Due to failures of interconnected equipment in recent earthquakes, it is suspected that the seismic interaction of the flexible conductors with the equipment during a strong ground motion could cause additional unpredicted forces, resulting in damage or collapse of the equipment they interconnect. This paper presents the results of an investigation into the dynamic behavior of flexible conductors by performing several shake table tests on a class of flexible conductors and the relevant 500-kV interconnected equipment used in substations throughout the province of British Columbia in Canada. The test specimen consisted of large scale models of the equipment items and the actual size flexible conductors. The shake table input records were synthetic earthquakes generated to fit an IEEE prescribed response spectrum. This investigation showed that the dynamic effect of flexible conductors must be considered when evaluating the seismic capacity of interconnected equipment.

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
