EXPERIMENTAL INVESTIGATION OF AN INNOVATIVE BEAM-TO-COLUMN CONNECTION UNDER CYCLIC LOADING
Bibliographic record
Abstract
The mechanical behaviour of steel is crucial in hybrid steel-timber systems, especially in areas prone to seismic activity.This paper presents a study of a novel semi-rigid connection that employs U-shaped steel plates as seismic fuses in a beam-to-column connection.The connection aims to introduce self-centring steel braced frames as lateral systems, combined with mass timber structures as a gravity load-resisting system, to enhance their structural performance against earthquakes.The fuses are designed to yield in axial compression or tension, with a bending combination that enables the connection to produce yielding at a specific moment level.The study focuses on the results obtained from cyclic fuse testing, connection testing, and comparing the connections to existing solutions to demonstrate their potential as a reliable and resilient option for mass timber buildings in seismic areas.The findings indicate that the developed connections provide reliable ductile behaviour, and timber elements can be protected from damage through the capacity protection provided by the fuses and their yielding mechanism.

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.
