Abstract
A reliability-based evaluation of the CSSBI 12M provisions for composite steel deck in the construction stage is presented. Deck reliability was analyzed for strength and deflection limit states with first-order reliability method for a large number of slab configurations typically used in North America. The results demonstrate that reliability indices for about 31% of all considered cases do not meet the CSA S136 requirements. Modifications of the CSSBI 12M construction loads are presented. The revised construction loads result in reductions of maximum unshored construction spans by 3% on aver- age (with a maximum reduction of 7%) and better deck reliability, which meets the CSA S136 requirements and is more uniform across the typical design parameters when compared to the current design provisions.

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 it
