Cross-Laminated Timber Concrete Composite Systems for Long-Span Floors
Bibliographic record
Abstract
Experimental investigations on full-scale (9.6 m) and half-scale (4.8 m) cross-laminated timber (CLT)-concrete-composite (TCC) slab bands are presented. The out-of-plane shear and ultimate flexural capacities of these TCC floors utilizing several types of shear connectors were determined. The TCC system was comprised of a 245 mm thick, 7-ply CLT with 150 mm concrete topping joined with shear connectors. The efficiency of three types of shear connectors: self-tapping screws, steel kerf plates, and proprietary glued-in Holz-Beton-Verbund (HBV) connectors was evaluated. Six series of floor systems, one control series of raw CLT floors (without concrete topping) and five TCC series, were tested for a total of 6-half scale control slabs, 18-half scale, and 6-full scale TCC slabs were tested under four-point bending. The results from this research were utilized to make project-specific design decisions for “The Arbour,” a 10-storey mass timber building for George Brown College, located in Toronto, Canada.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
