Structural Performance of Shear Deficient Beams with High Performance Reinforced Concrete Jacket
Bibliographic record
Abstract
This research investigates the performance of shear deficient concrete beams strengthened with reinforced jackets made of three different high performance concretes (HPCs) namely engineered cementitious composite (ECC), ultrahigh performance concrete (UHPC) and normal self-consolidating concrete (SCC) subjected to static monotonic and fatigue loading[.] The influence of HPC jackets is described based on strength, stiffness, energy absorbing capacity, steel/concrete strain developments and failure modes. Shear deficient beams with UHPC jacket showed highest strength, energy absorption capacity and ductility followed by those with ECC and SCC jackets. Shear deficient beams with UHPC jacket exhibited flexural failure. ECC jacketed beams subjected to fatigue loading exhibited lower stiffness, energy absorption capacity and strength degradation compared to their UHPC counterparts. This research confirms the viability of using ECC and UHPC as repair materials for the structural components.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
