Simulating the Role of Axial Flow in Stay Cable Vibrations via a Perforated Wake Splitter Plate
Bibliographic record
Abstract
Cable-stayed bridges have become progressively popular since 1955, mainly because of their modest requirement on ground anchorage condition, efficient use of structural material, higher stiffness, and economy compared to suspension bridges. The inclined and/or yawed orientation of bridge stay cables results in the formation of secondary axial flow on the leeward side of cable surface, which is believed to be one of the contributing factors exciting some unique wind-induced cable vibration phenomena. To clarify the role of axial flow in triggering aerodynamic instability of stay cables, a numerical study has been conducted to indirectly examine the axial flow effect via a perforated splitter plate placed along the central line of a circular cylinder wake. Results show that the presence of a perforated wake splitter plate would play a similar role as the axial flow in affecting the strength of von Kármán vortex shedding. Reductions on the fluctuating amplitude of the instantaneous lift and drag, as well as the mean drag, are also observed, which would ultimately affect the aerodynamic response of the studied cylinder.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
