Abstract

fetched live from OpenAlex

Examination of the critical observed temperature profiles will lead to the following conclusions: 1 Thick bottom slabs in deep sections (Sections 1 and 2) lead to lower than predicted temperatures and significant tensile stresses in these slabs. 2 The difference in temperature between the two webs of box girders are the source of a horizontal thermal gradient in deep box girder sections (Sections 1 and 2). For shallower section (Section 3), this was not observed. 3 The effect of horizontal temperature gradient cannot be ignored for deep sections when calculating continuity stresses. For shallow section this can be ignored. 4 The maximum seasonal displacement the bridge experienced during the 3-year period was found to be 226 mm. The Canadian standard CSA-S6-00 gives a good estimate for maximum temperature but seriously underestimates minimum temperature and differential temperature, for deep sections. Also, the code lacks guidance regarding design values for horizontal differential temperature.

Full frame distilled prediction

Teacher imitation

Not 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.
