Abstract
Abstract A review of seismic design solutions for connections is presented in this paper, with particular focus on methods that are already “pre‐approved” or “acceptable to code” for use by engineers in steel‐framed structures using hollow sections. This review is intended to illustrate the limited options currently available to structural engineers. The survey mainly covers European and North American design solutions, but the latter are also heavily influenced by Japanese practice. The scope includes both braced frame connections (utilizing hollow sections for the bracing members at least) and unbraced frame connections (utilizing hollow section columns), the latter including both rigid and semi‐rigid beam‐to‐hollow section column connections. Dissipative and non‐dissipative connection types are considered where appropriate. Emphasis is placed on connection configurations and concepts rather than detailed design information, but references to other sources are given for further details. Areas in which there is a paucity of established design guidance are noted, and the review concludes with recommendations for further research and development regarding specific types of connections to hollow sections subjected to seismic loading.

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
