Abstract
This paper evaluates the performance of moment-resisting bolted timber connections with self-tapping wood screws acting as perpendicular-to-grain reinforcement. Considering an unreinforced joist-to-column connection with slotted-in steel plates as baseline, an increase in capacity by a factor of 1·7 was observed when the connections were reinforced with self-tapping screws under reverse cyclic loading. This was further increased by 22·5% when the bolt diameter in the reinforced connection was increased from 19·0 to 25·4 mm. Reducing the edge distances of the bolts in the reinforced connection provided addition gain in capacity of 35·3% to a total capacity increase by a factor of 2·9 when compared to the unreinforced connections while maintaining very ductile behaviour. The results show that it is feasible to create ductile and high-capacity moment-resisting bolted timber connections with self-tapping wood screws as reinforcements.

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.
