Behaviour of flexural plastic hinges under high seismic shear with consideration of concrete strength
Bibliographic record
Abstract
A successful seismic design for a reinforced concrete element is one that can postpone the shear failure until the required ductility and deformation capacity are obtained. After flexural yielding, shear deformations are the main causes for strength and stiffness degradation. An experimental program was carried out to explore the shear behaviour of flexural plastic hinges of elements constructed with different concrete strengths (30–175 MPa) tested under load reversals. The specimen represented a beam–column assembly and was designed to have the inelastic deformation at the beam end only. The research investigated the effect of shear deformations on the hysteretic behaviour and stiffness deterioration, cyclic shear demands, shear resisting mechanisms, and the effect of concrete strength on the hinge shear strength. It was found that the effect of concrete strength on beam shear strength under cyclic loading differs from that under unidirectional loading.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
