Abstract
This paper presents an experimental and analytical study on slender concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars. The experimental program included ten concrete columns with rectangular cross-section (203×305 mm) where nine of them were reinforced with #6 GFRP bars and one of them was reinforced with steel rebars. Three different reinforcement ratios of 4.70, 2.82, and 2.04 as well as four slenderness ratios of 17, 22, 40, and 60 were considered under two load eccentricities of 0.1 and 0.25 of width of the cross-section. The analytical model considered the material nonlinearity as well as the geometric nonlinearity. The model was verified against an independent experimental program. The model showed that as the load eccentricity and slenderness ratio increase, the load capacity decreases and as the reinforcement ratios increases, the load capacity slightly increases which shows effectiveness of GFRP bars in compression.

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
