Abstract
A structural reliability analysis was performed on concrete masonry under concentric axial compression to examine the reliability levels for masonry buildings designed to the current Canadian masonry standard CSA S304.1-04 (2004). The first order second moment method was used to carry out the analysis. Prism compressive strength for hollow and grouted concrete masonry was used as the model. Over 300 specified masonry compressive strength values were computed using test results available from North American investigations, mostly Canadian. The material and geometry statistical data needed were obtained from several Canadian concrete masonry producers. Based on the findings of this investigation, it is recommended that unreinforced masonry be assigned a material resistance factor (φm) different from reinforced masonry. For masonry members under compression, it is proposed that the current φm be increased from 0.6 to 0.65 for reinforced masonry and decreased from 0.6 to 0.5 for unreinforced masonry. The proposed factors correspond to reliability indices of 3.5 and 3.8 for reinforced and unreinforced masonry, respectively.

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
