Abstract
This work is one of the four companion papers associated with the Canada/US (CANUS) collaborative project: Harmonization of Canadian and American Masonry Structures Design Standards. This particular paper specifically delves into a comparison of the design and detailing provisions for masonry beams in the U.S. and Canada. The scope of the investigation covers the similarities and divergences between the two design standards (CSA S304-14 and TMS 402-16), through first a comparative discussion of the provisions followed by parametric studies that illustrate the differences quantitatively. Several areas of further investigation are identified as a result of this work, which if addressed, may improve and harmonize the two standards and practices. For instance, the 𝜒 factor utilized in C SA S 304-14 amplifies the divergence such that most masonry beam designs that have been safely constructed in the U.S. are not possible in Canada. In contrast, TMS 402-16 does not have clear guidance on deflection limits or intermediate reinforcement for regular beams; and a reconsideration for modulus of rupture values may be warranted, as the code-provided values are based on historic wallette tests instead of beams.

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
