Abstract

fetched live from OpenAlex

<p>Structural Insulated Panels (SIPs) can significantly reduce emissions produced by our homes and commercial buildings by reducing the amount of energy used for heating and cooling. A SIP is composed of expanded polystyrene insulation (EPS) board laminated between two oriented-strand boards (OSB). SIPs are used all over the world because of their superior strength and quality build. The objective of this thesis it to evaluate the effectiveness of the foam core in providing composite action in SIPs under axial and bending loads to meet both the strength and serviceability requirements. This thesis presents the experimental program and the results of 32 full-size panels tested to-collapse at the Structures Laboratory of Ryerson University. The data generated from this extensive experimental program can easily be used to determine the load carrying capacity of the SIP walls when subjected to axial compressive loading or combined axial compressive loading and bending moment. </p>

Full frame distilled prediction

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.
