Novel anchor-jointed precast shear wall: testing and validation
Bibliographic record
Abstract
Precast concrete shear walls are used to resist lateral loads in low- to medium-rise buildings. This paper introduces an innovated joining technique for these precast walls that will reduce the possibility of concrete damage and capital loss during earthquake events. The proposed technique consists of precast panels joined together and to the base using threaded steel anchor bolts, which in turn makes the construction process easier and faster. An experimental programme is conducted to validate this system and characterise its behaviour under lateral loads. Four reduced-scale wall specimens are tested under monotonic in-plane horizontal load. The lateral strength, ductility and possible modes of failure are used to evaluate the connection performance. The joined precast shear wall exhibits a high non-linear deformation without any signs of panel damage, which can be attributed to the gap opening and steel yielding at the connection plane. This indicates that the steel anchor bolts at the connection can be designed to act as structural ductile fuses.

How this classification was reachedexpand
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.
