Abstract

fetched live from OpenAlex

The lateral performance of structurally nonsymmetric diagonal-braced wood shear walls used in post-and-beam timber buildings was investigated with laboratory testing and computer modeling. Monotonic and reversed cyclic tests were performed to study the capacities of a total of eight full-scale shear walls, with and without gypsum wallboard sheathing. Significant increases of strength, stiffness, and energy dissipation were observed in the shear walls with the additional gypsum wallboard sheathing. An efficient mechanics-based wood shear wall model was then introduced to represent the hysteretic load–drift behavior of these diagonal-braced walls. The predicted seismic response of the model agreed very well with the shake table test results of a simple one-story post-and-beam structure, making it possible to develop, in future research, structural models for more-complicated post-and-beam buildings with good computational efficiency and accuracy.

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.
