A Timber-Concrete Composite Slab System for Use in Tall Buildings

The increasing demand for fire resistance and sound insulation in multi-storey buildings has made composite slabs of board stacks (side by side timber members) and concrete a desirable structural system. While it has been implemented in several cases, the floor plan is restricted because the anisotropy of timber requires continuous support of the board stacks. Steel slim-floor profiles can be integrated into the timber–concrete composite slab, acting as a continuous support. In comparison to usual reinforced concrete slabs, the reduced dead load allows larger spans with the same thickness, which requires fewer columns and extends the range of the application for the structural system.
