Abstract

fetched live from OpenAlex

ACI 318-05 considers that unbalanced moment, Mu , transferred between column and slab is resisted in part (γνMu) by shear and the remaining part, [(1−γν)Mu] by flexure. The code specifies the fraction γν and permits, in Section 13.5.3.3, that the fraction can be decreased when two requirements for the shearing force, Vu , and for the flexural reinforcement ratio, ρflex , are satisfied. Nonlinear finite-element analyses for interior, edge, and corner connections are employed to calculate the value of γν at all load stages up to failure, indicating that the γν reduction as permitted by 13.5.3.3 is not justified. This statement is supported by experimental interaction graph.

Full frame distilled prediction

Teacher imitation

Not 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.
