Abstract
The design of a rectangular hollow-section K-connection in which the branches are welded toe-to-toe to the chord is not permitted at present in design guides and codes. To illustrate the feasibility of such connections, two full-scale cold-formed welded rectangular hollow-section K-connection laboratory tests, including one control specimen and one zero-gap specimen, are presented. A new chord face shear analytical model based on a yield-line mechanism is proposed for such connections, and its validity was evaluated against the experiments. Nonlinear finite-element connection models were built and validated against the laboratory tests, and a numerical parametric study was performed on similar connections with a broader range of parameters. From the results of the finite-element study, an empirical connection strength model was also generated by regression curve-fitting. Based on the experimental and numerical data, the proposed chord face shear analytical model is recommended for design of rectangular hollow-section zero-gap K-connections. The gap size can also be increased up to the summation of the two branch thicknesses.

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
