Abstract
During its design life, a structure has to satisfy several performance requirements. It is now common to express all safety requirements, as well as some functionality requirements, in reliability based formats. Failure consequences (hence target reliabilities), structural behavior, capacity, loads and modeling uncertainties and thus the limit states themselves are different at these various performance levels, and the design must take these aspects into account. This paper develops optimal partial safety factors over a range of structural configurations for the design of partially prestressed sections in flexure corresponding to two performance levels — cracking and collapse — satisfying respective target reliabilities. Detailed numerical examples and derivations are presented. The role of relative failure consequences at the two performance levels in determining the governing limit state, the “balance point” where both limit states are active, and the possible implication on maintenance strategies, meas...

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
