Structural Commentaries (User's Guide: NBC 2015: Part 4 of Division B)
Bibliographic record
Abstract
The Commentaries presented herein serve to provide designers with detailed design information that will assist them in the application of Part 4 of Division B of the National Building Code of Canada (NBC) 2015. They contain background information and suggested approaches to certain design issues; their provisions are not mandatory requirements of the NBC. The information set forth in these Commentaries does not cover all conditions and types of structures that occur in practice. For unusual types of structures, specialized information, such as theoretical studies, model tests or wind tunnel experiments, may be required to provide adequate design values. It should also be noted that new information can become available at any time. As such, designers are encouraged to obtain the latest and most appropriate design information available.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
