EXPERIMENTAL STUDY OF GROUTED DOWEL CONNECTIONS UNDER MONOTONIC LOAD
Bibliographic record
Abstract
The increased use of precast shear walls in multi-story buildings in Canada necessitates an immediate comprehension of their behavior and the development of design guidelines to ensure their adequacy. To achieve this, a thorough understanding of the connections' response is essential, as their design significantly impacts the overall response of the wall. This paper introduces a study to investigate the response of the grouted dowel connection, a horizontal connection, under monotonic and cyclic load. The initial tests in this study under monotonic loads, outlined in this paper, revealed that the monolithic section of the wall exhibited 3.8 times greater elongation capacity compared to the grouted dowel jointed connection. Additionally, with the jointed grouted dowel connection, deformations were notably concentrated at the grouted joint. The experimental results from this study are crucial for model development for localized response and will be incorporated into models for diverse building types, facilitating the evaluation of system-level ductility in precast shear wall structures using grouted dowel connections.

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.
