Two-way Spanning CLT-Concrete-Composite-Slabs

Timber-concrete-composite, cross-laminated timber, two-way spanning slab, shear connection, notch, fullythreaded screw, plate load-bearing behaviour, force-fitting element joint.The applicability of the TCC-construction methodfor two-way spanning systems was demonstrated.Solutions for the arrangement of shear connectors andCLT-layers within the slab were found. The influencesof torsion on the plate load-bearing behaviour wasdetermined. With glued-in reinforcement bars,a connection was developed, which meets therequirements of stiffness and practical buildability. Acomparison with one-way spanning TCC-slabs showsdistinct material reduction potentials.The next step is to develop a calculation model fortwo-way spanning CLT-concrete-composites that canbe applied with established instruments in practice.
