Experimental Investigation on Shear Capacity of Reinforced Concrete Precracked Push-off Specimens with Externally Bonded Bi-Directional Carbon Fibre Reinforced Polymer Fabrics
Bibliographic record
Abstract
This paper exemplifies the results of shear transfer capacity and modes of failure of the precracked Reinforced Concrete (RC) push-off specimens bonded externally with bi-directional Carbon Fibre Reinforced Polymer (CFRP) Fabrics. External strengthening with Fibre Reinforced Polymer (FRP) fabrics is an evergreen technique for improving the structural performance and life span of the existing reinforced concrete structures. An experimental investigation was conducted to study the effectiveness of CFRP as an external reinforcement. The bi-directional CFRP fabrics were applied using two-component epoxy. The push-off specimens were cast and reinforced by varying the amount of internal shear reinforcement across the shear plane. The tests were performed with pre-existing crack along the shear plane of the push-off specimens prior to the application of direct shear load. The shear stress enhancement of the strengthened push-off specimens varies in the range of 7% to 56% over the unstrengthened push-off specimens.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
