Experimental characterization of the bond performance of a new type of glass fibre-reinforced polymer rebar for application in concrete structures
Bibliographic record
Abstract
This paper presents experimental results obtained from direct pull-out tests of commonly used and a new type of glass fibre-reinforced polymer (GFRP) rebar. The new GFRP rebar, developed by the authors, has a surface structure composed of milled glass fibres and epoxy resin, and its appearance resembles that of ordinary steel rebar. The effects of surface type and increased amounts of milled glass fibres in each rib on bonding with concrete were investigated to characterize the bond performance of the new type of GFRP rebar. The results indicated that the new type of GFRP rebar performed better with a higher bond strength to concrete compared with other tested types of GFRP rebar. Moreover, the rib bearing resistance and energy absorption appeared to increase with increased milled glass fibre in the ribs, which dominated the overall bond behaviour.

How this classification was reachedexpand
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.
