Abstract

fetched live from OpenAlex

Aging reinforced concrete structures have been not only subjected to in-service loading but also exposed to an aggressive environment which will cause corrosion of reinforcing steels embedded in concrete. An approach that is akin to the nested reliability method is proposed for the time-dependent reliability analysis of bridge girders under corrosion attack. The approach can be used to investigate directly the effects of the uncertainty in surface chloride concentration and critical chloride concentration for corrosion initiation, and the possible nonlinear corrosion growth on the reliability. The consideration of the nonlinear corrosion growth is due to the fact that the corrosion current density may not be a constant. Analyses of the reliability of bridge girders to the parameters governing the corrosion are performed using the proposed approach and typical statistics of load effects and material strength parameters. Results suggest that consideration of the nonlinear corrosion growth is very important in determining the remaining service life of existing concrete structures, and that the uncertainty in the variables controlling the corrosion initiation has only small effect on the estimated time-dependent reliability.

Teacher imitation

Not 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.
