Abstract
Abstract Novel bamboo I-beams fabricated from bamboo oriented strand boards as structural members were investigated. Bending tests were performed to determine the stiffness and strength properties of bamboo I-beams. The results showed that the stiffness and strength properties exceeded the requirements of APA EWS Performance-Rated I-joist in PRI-400-2012. Increasing section depth had obvious effect on the ultimate load capacity, stiffness and failure mode of bamboo I-beams. Moreover, the bending properties of bamboo I-beams were also affected by flange materials, joint type in web, and reinforcement of flange finger joints. The strain measurements indicated that the plane assumption could be applied to the bamboo I-beams. Based on the stiffness calculation formula of I-beams recommended in Canadian standard and the moment capacity calculation formula corresponding to each failure mode of I-beams, the calculated stiffness and ultimate load capacity of specimens were relatively close to the experimental results.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
