An Investigation into the Flexural Behaviour of GFRP Reinforced Concrete Beams
Bibliographic record
Abstract
Non-corroding materials, such as Fibre-Reinforced Polymer (FRP) bars, are now being used as reinforcement for reinforced concrete structures in order to extend their lifetime and minimize maintenance costs. Because of the softer and brittle behaviour of GFRP bars, behaviour of structural members reinforced with this material is different than that of steel-reinforced members. In this study, 16 GFRP reinforced beams were constructed and tested under flexure and shear loads to failure. Effects of different variables, such as amount of longitudinal and lateral reinforcements, type of bars and concrete strength, were investigated for their effects. The flexural provisions of design codes, namely CSA S806-12, CSA S6-06, and report ACI 440.1R-06, were evaluated against the test data. The main provisions investigated are failure modes, ultimate strength, moment-curvature response, deflection, crack widths, and deformability.

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.
