Abstract
The structural behavior of welded hollow structural sections (HSS) connections in which one member is laterally offset from the plane of a connection is investigated experimentally and compared with corresponding planar connections. Sixteen full-scale test connections, consisting of either T or N configurations fabricated from class C HSS, were tested at load levels comparable with those expected to occur in actual trusses. In all cases the mode of failure was by localized large deflections of the flange face and sidewalls of the compression chord. It was found that in the case of T connections, the reduction in capacity due to offsetting a member by as much as 17% of the width of the chord member from the central plane of the truss was marginal. N configurations, whose diagonal members were offset by 8% of the width of the chord member, showed a slight increase in ultimate strength. The design values obtained using both AISC LRFD and CIDECT specifications are compared with the test results where appropriate.

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 it
