Effect of Reinforcement Spacing on the Behaviour of Out-Of-Plane Concrete Block Masonry Walls
Bibliographic record
Abstract
Stack pattern concrete masonry walls are commonly viewed as woefully insufficient load bearing walls compared to those constructed in running bond. For this reason, in Canada stack pattern construction is not permitted for load bearing walls. This research experiment was carried out to directly compare stack pattern construction to running bond and determine the differences in effective compression zone width. The experiments consisted of six partially grouted wall specimens, three of which were constructed in running bond and the other three in stack pattern. Three different rebar sizes and spacings were used to create equal effective reinforcement area with variable spacing. The walls were loaded axially and out-of-plane via four-point bending. There were 24 prisms tested along with these walls to determine the compressive resistance of the partially grouted walls. The test results found the stack pattern walls to be much more effective than they are commonly believed to be.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
