Cross‐sectional capacity and flexural buckling resistance under fire conditions
Bibliographic record
Abstract
Abstract This paper presents an experimental study on the cross‐sectional capacity and flexural buckling resistance under fire conditions. Steady state stub and slender column tests were carried out at ambient and elevated temperatures on square and rectangular hollow sections as well as H‐sections. In addition, transient state slender column tests were performed on H‐section test specimens. The compressive load was applied centrically or eccentrically to the test specimens. The paper presents the testing programme, the geometry of the test specimens including initial geometrical imperfection measurements, elevated temperature material properties, test setup, the execution and the results of the stub and slender column tests. Querschnitts‐ und Knickwiderstand im Brandfall – Experimentelle Untersuchungen. Der Beitrag analysiert mit Hilfe experimenteller Methoden den Querschnitts‐ und Knickwiderstand im Brandfall. Die stationären Versuche zum Widerstand gedrungener und schlanker Stützen unter Druck‐ sowie kombinierter Druck‐ und Biegebeanspruchung bei Normaltemperatur und erhöhten Temperaturen wurden an Hohlprofilen sowie H‐Querschnitten durchgeführt. Zusätzlich wurden schlanke Stützen unter transienten Versuchsbedingungen analysiert. Der Beitrag stellt das Versuchsprogramm, die Geometrie der Versuchskörper einschließlich geometrischer Imperfektionen, die Materialeigenschaften bei erhöhten Temperaturen, die Versuchseinrichtung sowie ‐durchführung und die Ergebnisse der Versuche zum Querschnitts‐ und Knickwiderstand dar.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
