Orthotropic plate analysis model for estimating live load moment and deflections in reinforced concrete bridge deck slabs between longitudinal girders
Bibliographic record
Abstract
The equation for calculating the applied transverse moment in reinforced concrete deck slab in slab-on-girder bridges under truck loading in the Canadian Highway Bridge Design Code is dated back to 1930.It does not include the effect of the transverse-tolongitudinal flexural stiffness and the torsional stiffness.In addition, the code does not provide equations for the longitudinal moment and deflection.This paper presents the application of the orthotropic plate theory to determine the applied transverse and longitudinal moment and deflection under different truck loading conditions.The key parameters considered in this study included the slab span ranging from 1 m to 4 m, single-or two-lane loaded with Canadian trucks, different truck axles, and transverse-to-flexural stiffness ratios ranging from 1 to 4. The data generated from this study was used to develop empirical equations for the transverse and longitudinal moments for ultimate and fatigue limit state design and deflection for serviceability limit state design.

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.
