Abstract
Structural behaviour of reinforced beam-column frames made with Self-Consolidating Concrete (SCC), Engineered Cementitious Composite (ECC), and Ultra-High-Performance Concrete (UHPC) without shear reinforcements under lateral cyclic loading is compared based on experimental hysteretic load-displacement/rotation response, concrete/steel strain development, failure modes, crack development, energy dissipation, stiffness degradation, ductility, and viscous damping characteristics. Fiber-reinforced ECC/UHPC highly improved the seismic characteristics of shear-critical frames by exhibiting higher ductility with lower stiffness, better damping with high energy absorbing capacity and ductile joint flexural rather than brittle column shear failure. Code equations should be modified to predict improved shear resistance of ECC/UHPC shear critical frames.

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
