Validation and application of analytical design approach for multi-storey platform-type CLT shear walls
Bibliographic record
Abstract
Mass timber products in general and cross-laminated timber (CLT) in particular, have garnered significant attention in the construction industry due to their structural and environmental benefits. Extensive efforts have been undertaken to investigate the lateral behavior of CLT shear walls , involving experimental tests and analytical developments. However, experimental validation of analytical models for calculating the resistance and lateral deformation of multi-storey platform-type CLT shear walls are not available. To close this gap, two-storey shear wall models, developed using the calibrated properties from connection-level experimental tests, were validated with the results from two-storey CLT shear wall tests. Subsequently, analytical models for six-storey CLT shear walls were developed to investigate the behaviour of connections and their contributions to the lateral behaviour of mid-rise CLT shear wall systems. A capacity-based design procedure was successfully implemented, ensuring proper capacity distribution along the building height. The significant influences of aspect ratio and tension strap design on inter-storey drift and shear wall resistance was highlighted. Additionally, with proper design, rocking behavior dominated, and the bending deformations were limited to less than 30 %, meeting the current design requirements.

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.
