Low grade pine subject to loading exhibits a poor predictability when used in structural applications. Australia produces a large amount of low grade timber yearly which is sold at a loss due to its unreliable performance characteristics. This dissertation investigates the structural performance of slab units manufactured from low grade timber when used to form a floor slab.
Physical testing and finite element analysis modelling have been used to determine the limitations of low grade timber floor slabs. This study involved determining which of the strength and serviceability criteria governs design, along with an investigation into the performance of bugle head batten screws used to connect low grade slab units to form a floor slab. The findings of these investigations are summarised into a chart for the deflection based design of low grade timber floor slabs, and graphs describing connection performance based on various loading situations.Investigations have concluded that utilising low grade timber in floor units increases the reliability of the product considerably. Connections can also be made that have sufficient strength to resist any forces applied between slab units
