Abstract

fetched live from OpenAlex

In light wood frame buildings, diaphragm flexibility influences the load distribution between shear walls under lateral load induced by earthquake or wind action, which is important for structural design.A multiple spring model with the ability to represent the load-transferring behaviour of this complex lateral load resisting system of light wood frame buildings was developed.The developed model was validated with results from the more sophisticated model, spring deep-beam model.The lateral load distribution between shear walls with various stiffness ratios of diaphragm to shear wall was also investigated.Based on preliminary findings from this study, contrary to common belief, the forces transferred by a semi-rigid diaphragm to the supporting shear walls, may be higher than those predicted by flexible and rigid diaphragm assumptions.

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.
