Abstract
Abstract This paper presents a model method for predicting the immediate and time‐dependent strains and stresses in concrete structures with or without prestressing. The time‐dependent parameters that enter the analysis include creep and shrinkage of concrete and relaxation of the prestressing reinforcement. The method is based on analysis of strain distribution in individual sections by satisfying equilibrium and compatibility. The method presented is comprehensive; it applies to concrete structures reinforced with steel or fibre‐reinforced polymers, and to composite sections comprising concrete and structural steel parts. Calculation of the central deflection and end rotations of a straight member from curvature values at a number of equally spaced sections is illustrated. Available computer programs for use in the time‐dependent analysis are briefly described. The analysis steps are demonstrated by a flowchart and by numerical examples. The model analysis is verified by comparisons with published experimental results. Copyright © 2003 John Wiley & Sons, Ltd.

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
