Abstract
A calculation procedure is described for estimating crack shear stresses and crack slip displacements from average strain measurements made on reinforced concrete panels. Several series of panels, previously tested, are examined and crack shear-slip data are extracted. These data are compared against the predictions of previously developed crack slip models, as well as against an alternative constitutive model proposed herein. Reasonable correlation is found between experimental and calculated values, particularly at near-ultimate load conditions. It is then shown that including crack shear slip behaviour in a computational model results in improved accuracy in terms of predicted load-deformation response and ultimate load capacity for reinforced concrete elements such as panels, beams and shear walls. Further, it is shown that rigorously accounting for crack slip displacements results in a better representation of various subtle aspects of behaviour, such as the failure mode and the capacity of elements to deform and redistribute load.

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 it
