Abstract
Twelve high strength fibrous reinforced concrete deep beams ( HSFRCDB ) were tested under two point loading . All the beams were reinforced with main steel reinforcement ratio ( p ) of about 2.4 percent to avoid flexural failure . The shear span - to - depth ratio ( a / d ) of the beams was about 2 and the volume fraction of the steel fibre was 0.5 percent . The beams were tested for different vertical stirrup nominal strength ( pfy ) , ranging from 0.15 to 4.44MPa , horizontal stirrup nominal strength ( Pfy ) , ranging from 0.4 to 3.63MPa and vertical and horizontal ( combination ) stirrup nominal strength ( pfy ) , ranging from 2.57 to 8.07MPa in addition to one beam without stirrups . Test results indicate that horizontal stirrups has little influence on the magnitude of the failure load . The test results of this investigation as well as those available in the literature ( 244 high and normal strength concrete deep beams with stirrups ) were compared with predictions based on the ( ACI , BS , Canadian and New Zealand Codes ) and works of other investigators ( Zustty , Siao and Sarsam ) and a Proposed Equation . The ACI , BS and Saio Equations are simultaneously conservative with relatively low COV values . The Proposed Equation has the lowest standard deviation , COV and conservative predictions .

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
