Ultimate Strength of an SPS Bridge - The Shenley Bridge, Quebec, Canada
Bibliographic record
Abstract
The cross section of the Shenley Bridge suggests that it is simply a slab-on-girder bridge, even if the slab acts compositely with the three longitudinal girders. However the deck panels, with moderately sized but widely spaced edge stiffeners, span transversely between the girders and longitudinally the main girders act as deck stiffeners even though they are rather large and very widely spaced. Different proportions of deck thicknesses and stiffeners could give an orthotropic bridge approaching more usual proportions. The fundamental difference of the Shenley Bridge from the usual orthotropic bridge is that the deck plate is not a single steel plate stiffened with trough stiffeners but a steel Sandwich Plate System (SPS) that is stiff enough by itself, self stiffened if you will, to span many times the span of a single steel plate thus reducing the number of stiffeners markedly. A SPS unit consists of two steel faceplates bonded to an elastomer core. The design of the Shenley Bridge, erected in November 2003, to carry gravity loads, particularly as related to the SPS deck panels is discussed and the results of full scale static load tests are presented and analysed.

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.
