Bending, vibration and long-term performance of timber-concrete-composites floors

There is much potential for engineered wood products (EWP) to be used beyond low-rise residential construction when incorporating the notion of hybrid systems like timber-concrete- composites (TCC). The research presented in this paper experimentally determined the bending, vibration and long-term performance for a range of TCC systems in several EWPs. Strength and stiffness properties were validated on small-scale shear tests. Subsequently, full-size floor panels were tested for elastic stiffness and dynamic properties under quasi-static loading. Furthermore, floor panels are subjected to serviceability loads since summer 2015 with the environmental conditions and the deflections being monitored. This research provides insight to engineers into safely designing TCC floor systems for bending, vibration and long-term performance.
