DUCTILITY OF REINFORCED CONCRETE MASONRY SHEAR WALLS UNDER SEISMIC LOADING
Bibliographic record
Abstract
The possibility of achieving a high level of ductility by flexural yielding in fully grouted reinforced concrete masonry shear walls is evaluated. Six full-scale walls were tested to failure under reversed cyclic lateral loading to investigate the effects of the amount and the distribution of vertical reinforcement and the level of axial compressive stress on the inelastic behavior and ductility of reinforced masonry shear walls. The test results indicated that the top wall displacement at the onset of yielding of the vertical reinforcement was highly dependent on the amount of reinforcement and minimally affected by the level of axial compressive load. However, at maximum lateral loads, the wall displacements were less sensitive to the amount of vertical reinforcement and to the level of axial compression. Correspondingly, the displacement ductility was found to be very sensitive to the amount of vertical reinforcement compared to the level of axial compression. In general, high levels of ductility accompanied by relatively small strength degradation were observed for the test specimens.

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.
