Vibration Testing of Scaled Cable-Stayed Bridges
Bibliographic record
Abstract
<p>In this article, the development of a 1/75 dynamic small-scale model of the Hawkshaw Bridge and its modal identification are presented. The results are also compared with the vibration tests performed on the prototype structure. The Hawkshaw Bridge is a cable-stayed bridge in New Brunswick. The scaled model is 4.4 metres long compared to the actual length of 332 metres. The scale model was designed to stay within the elastic limits under the performed tests. Similitude laws were strictly followed to develop a structural model that complies with the dynamic similitude requirements. Random vibration sources were introduced to the scaled structure to simulate operational dynamic loads that the prototype structure experience. The response of the model was recorded using five tri- axial accelerometers. Using operational modal analysis, modal properties of the scaled model are estimated. The results were used to correlate the field vibration test data to the laboratory experiments.</p>

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.
