Influence of Web Geometry on Concrete Masonry Walls Subject to Out-of-Plane Loading
Bibliographic record
Abstract
An experimental program consisting of 27 partially grouted and reinforced walls was conducted to assess the impact of concrete masonry unit (CMU) web geometry on flexural response when subject to out-of-plane loading given changes to CMU geometry as adopted by ASTM C90 in 2011 that have yet to be vetted in Canada. All walls had the same overall geometry and were constructed with either regular stretcher units conforming to either CSA A165-14 or ASTM C90-23 or knock-out units conforming to ASTM C90-23. The configuration of the longitudinal reinforcement was also varied between wall series such one of that three reinforcing ratios resulted: 0.22, 0.44, or 0.66%. No notable differences in behavior resulted due to differences in the geometry of the concrete masonry units used in wall construction, though the grout columns as included in the reinforced cells appeared to mask the influence of web geometry.

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.
