Abstract

fetched live from OpenAlex

The behaviour of steel beam-to-column connections under thermal loading is understudied. When exposed to a fire, the members within steel structures expand during heating and contract during cooling, inducing potentially large connection forces. Within Canadian design, there exists flexibility for designers to consider more advanced computational practices that can optimize the fire protection design and allow for safer and more resilient design. A series of fire tests were undertaken, with three different methanol pool fire durations, to understand the deformation behaviour of steel beam-to-column connections when a localized thermal exposure is applied to the centre span of the beam. It provides a preliminary understanding of how the forces and heat are dissipated into the connections. Preliminary recommendations for the development of the relevant Canadian design code, Annex K within CSA S16-19, have been outlined.

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.

Teacher imitation

Not 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.
