Abstract
<p>The ACI 318 Building Code provides flexural EI stiffness values for elastic analysis of steel reinforced concrete buildings, with a moment of inertia &#119868;&#119868; equal to 0.7&#119868;&#119868;&#119892;&#119892; for columns, 0.35&#119868;&#119868;&#119892;&#119892; for beams, and 0.25&#119868;&#119868;&#119892;&#119892; for flat slabs at factored loads (1.0&#119868;&#119868;&#119892;&#119892; for columns, 0.5&#119868;&#119868;&#119892;&#119892; for beams, and 0. 35&#119868;&#119868;&#119892;&#119892; for flat slabs at service loads). This paper recommends design values of the moment of inertia for analysis of glass fibre reinforced polymer (GFRP) reinforced concrete members based on current ACI 440 design requirements. Results at the factored load level suggest using a value of &#119868;&#119868; equal to 0.4&#119868;&#119868;&#119892;&#119892; for columns and 0.15&#119868;&#119868;&#119892;&#119892; for beams and slabs. At the service load level, recommended values are increased by 50 percent to give 0. 6&#119868;&#119868;&#119892;&#119892; for columns and 0.225&#119868;&#119868;&#119892;&#119892; for beams and slabs.</p>

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
