Abstract
A model is presented that can predict the load-deformation response of reinforced concrete subjected to reverse-cyclic (seismic) shear. Average strains due to crack displacements are separated from concrete strains according to simple assumptions resulting in a rational model that can account for the two sets of cracks that are open when applied shear reverses direction. Closing cracks are assumed to close as a function of the compression stress applied normal to cracks, while opening cracks open as necessary to maintain compatibility of concrete and reinforcement strains. With the separation of strains due to crack displacements, simple material stress-strain relationships for concrete and reinforcement are sufficient to capture the complexities of reverse-cyclic response. The model accurately predicts underlying mechanisms such as accumulation of plastic strain in reinforcement, which defines the degree of pinching in the hysteretic response of reinforced concrete subjected to reverse-cyclic shear. Concrete shear failures are captured by a limit on ultimate shear strain that depends on the shear strain at first yielding of reinforcement and the ratio of shear stress to concrete strength.

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 it
