Abstract
This study investigates the structural performance of a newly proposed bolted connection for panelized modular structures, using high-strength bolts and extended plates, aimed at addressing Canada’s housing shortage, particularly in remote areas. A finite element model (FEM) was developed and validated against experimental data to evaluate the connection’s behaviour. A parametric study of 240 FEMs was conducted on unstiffened connections, examining the effects of extended plate thickness, bolt configuration, and bolt diameter. Results show these parameters significantly affect moment capacity, failure mode, and inelastic rotational behaviour. The bolt arrangement and quantity fostered a “strong column–weak beam” mechanism, enabling plastic hinging in the beam. Additionally, bolt diameter and plate thickness were found to govern ultimate rotation capacity and failure modes. To support practical application, design charts and a mathematical equation based on genetic regression were developed to predict ultimate capacity, thereby streamlining the design process and reducing trial iterations.

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 it
