[Abstract]: This research paper will investigate the viability of using Low/Utility grade timber to construct timber beams, plate members and solid wall structures via a Cross-lamination process known as CLT. More specifically it will aim to uncover an optimum set to material specifications and dimensions for an engineered panel design.

Due the many faults and defects in the utility grade timber it is often left to be used in wood chipping and wooden pallet manufacture, still this leaves a significant amount of product in storage, costing Hyne money. As well as producing a new structurally competitive product for Hyne Timber Australia, developing a method to structurally stabilise utility grade timber will drastically reduce wastage in the wood industry as well as provide an alternative to conventional brick and mortar building.

The modelling procedure will be undertaken in the finite element modelling software package Strand 7. These models are built upon the current known data for the mechanical properties of Slash Pine. Utilising the known modulus of elasticity and the orientation of grain direction, a finite analysis can be performed, calculating stress and moment distributions and deflections under applied loading.

The data gathered from these models will then be used to draw comparisons from standard slab performance tests and the expected usage of CLT panels to help assess with further research whether the development of CLT panels from timber of sub-par quality is viable.
