Abstract
We introduce a compiled database of 100 full-scale steel beam-to-column connections that failed due to flange fracture. This database focuses on welded flange connections tested in the past 50 years, including tests with strong panel zones and box columns that have been excluded from previous collections. To extend the information from each experiment beyond the recorded response, this database is augmented with high-fidelity structural models carefully calibrated to the test data using a semi-automatic algorithm. Once calibrated, these models offer a versatile method to decompose the total displacement response of the connections in beam, panel zone, and column deformations and extract more detailed response quantities, such as the flange’s stress history. This augmented database enables a deeper understanding of the causes of flange fracture and an assessment of the common rotation limits in ASCE/SEI 41 employed for simulating fracture. Results show that these rotation limits have a considerably large error. Furthermore, these rotation limits are incapable of either identifying the flange that would fracture first or simulating the opening and closing behavior of a fractured flange. The flange’s stress histories extracted with the models is a more efficient demand parameter to characterize fracture behavior.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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
