Collapse Behavior of Platform-Type CLT Construction Using Shake-Table Experimental Tests
Bibliographic record
Abstract
Cross-laminated timber (CLT) walls generally have higher rigidity and seismic resistance capacity, and it was predicted that the CLT building height restrictions could be relaxed in regions with higher seismic hazards. The collapse of CLT buildings is not well understood because research that investigates the limit state performance is scant. In this paper, incremental shake-table tests were conducted on two full-scale 2-story platform-type narrow-panel CLT buildings, W1 and W2, to investigate the collapse limit state. W1 featured two 1 m wide CLT shear walls per story, whereas W2 had a single 2 m wide CLT shear wall per story. The response of W1 was governed by rocking walls, whereas W2 was dominated by sliding at higher seismic intensities. Neither W1 nor W2 collapsed at the seismic excitation of JMA Kobe NS 140%, at which the maximum interstory drift ratios of 8.8% and 5.9% were achieved. The system has sufficient energy dissipation mechanisms, but the need for an overall system-level design that considers innovative connections is apparent.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
