CFRP grid embedded in mortar for strengthening of shear-critical RC beams
Bibliographic record
Abstract
A carbon fibre-reinforced polymer (CFRP) grid embedded in mortar (CGM) is an innovative strengthening system that has similar benefits to fibre-reinforced polymer (FRP) strengthening systems for concrete structures, but overcomes such drawbacks as poor compatibility with concrete substrate and lack of vapour permeability. A study was conducted to investigate the effectiveness of the CGM composite system to strengthen shear-critical reinforced-concrete beams. The results show that a CFRP grid embedded in mortar is effective in enhancing the load-carrying capacity of shear-critical reinforced-concrete beams. However, the effectiveness of CGM strengthening reduces with the presence of stirrups. In addition, the CGM strengthening slightly reduces the shear strength contribution from internal stirrups. The experimental shear strength contributions were also compared with predicted values based on North American FRP design guidelines with some modifications.

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.
