Cross-Laminated Timber Concrete Composite Systems for Long-Span Floors
Publication: Structures Congress 2022
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.
