Analytical modeling of bond stress at steel-concrete interface due to corrosion
Bibliographic record
Abstract
An analytical model that describes the deterioration of bond strength, due to corrosion of steel reinforcement, at the steel-concrete interface in a reinforced concrete is developed. Concrete is assumed as a thick-walled cylinder subjected to internal pressure exerted from the growth of corrosion products on the concrete at the steel-concrete interface. The concrete in the inner cylinder is considered as an anisotropic material with stiffness degradation factor as an exponential function, while at the outer cylinder, the concrete is treated as an isotropic material. A frictional model is used to combine the action of confining pressure resulted from radial pressure produced by principal bar ribs on surrounding concrete, and corrosion pressure resulted from the expansion of corrosion products. The results of the proposed model are validated with experimental results by several researchers and a good agreement was noted; this shows that the derived analytical model was able to satisfactory [sic] predict the reduction of bond strength between steel and concrete.

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.
