Abstract

fetched live from OpenAlex

High-fidelity modelling used to predict the dynamic behaviour in terms of displacement-time history and failure mechanism of heavy timber elements are presented and validated.A material predictive model was implemented in ABAQUS through a dynamic user subroutine using continuum damage mechanics.Full-scale experimental test results were analysed and used to validate the modelling predictions.Compared with the experimental test results, the finite element models simulated the displacement-time histories and overall failure behaviour reasonably well.The accurate prediction of failure modes and overall responses of timber elements, including those with complex properties such as cross-laminated timber, is important to ensure safer designs, and lead to a better overall understanding of the material behaviour when subjected to very short duration loading.

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.

Not 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.
