Longitudinal Forces on Transmission Towers due to Non-Symmetric Downburst Ground Wire Loads
Bibliographic record
Abstract
Downburst thunderstorms are localized high-intensity wind events that are formed by an intensive downdraft of cold air that impinges on the ground causing high radial wind speeds. Spatial localization of downbursts causes unique oblique load cases on long-span structures such as transmission lines that do not occur during synoptic winds. This loading scenario causes an unsymmetrical wind loading along the spans of the cables, resulting in an unbalanced longitudinal force acting on the transmission tower of interest. This longitudinal force is highly nonlinear; it depends on the material and geometrical properties of the cables. Therefore, a nonlinear analysis should be conducted considering the various possibilities of downburst-cable configurations and the cable material and geometrical properties. This paper focuses on developing a simplified and manual approach to estimate this damaging longitudinal force, which develops in ground wires of transmission lines.

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.
