Behaviour and Design of I-Shaped Aluminium Sections
Bibliographic record
Abstract
Aluminium alloys exhibit a non-linear stress–strain material response with significant strain-hardening effects. Whereas the latter shall be considered in the design of aluminium elements, they are largely ignored in most design codes, such as Eurocode 9 and the Canadian Standards. Preliminary studies on typical aluminium I-shapes indeed indicated that as much as 40% extra resistance could be reached through more accurate and appropriate design recommendations. Accordingly, an original design approach based on the Overall Interaction Concept (O.I.C.) is developed to better account for the actual behaviour of aluminium structural shapes. In this respect, non-linear finite element models are developed within ABAQUS and further validated against experimental data. Subsequently, comprehensive parametric studies are performed to collect numerical reference results, and comparisons are performed with resistance predictions from well-known design standards. The performance of the newly developed O.I.C.-based design approach is shown to significantly improve accuracy, safety, consistency, and reliability levels.

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.
