Abstract
This work examines the major parameters that influence the shear strength of reinforced concrete ( RC ) beams without web reinforcement . These include the shear span / depth ( a / d ) ratio ( between 2.0 and 7.1 ) , concrete compressive strength f . ( between 20.0 MPa and 101.9 MPa ) , the longitudinal steel ratio ( p ) ( between 0.00251 and 0.06620 ) , and beam size ( bnd ) . 271 RC beams failing in shear available in the literature are used to study the effect of the indicated major parameters on the strength of Normal Strength Concrete ( NSC ) and High Strength Concrete ( HSC ) . Proposed design equations are compared with the existing shear design relationships of the ACI Code 318M - 02 , BS 8110 , Canadian Code , New Zealand Code and Zsutty equation to predict the shear capacity of RC beams . For all methods considered , the ratio of shear strength of beams VTTEST to the design shear resistance VrDES is calculated . The proposed design equations lead to safe design with a low coefficient of variation ( COV ) . This COV is only 18.6 percent which is significantly less than values obtained for other methods ( ranging between 28.5 to 43.3 percent ) .

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
