Abstract

Low grade timber 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 paper investigates the structural performance of small slab units manufactured from low grade timber when used to form a floor slab. Physical testing and finite element mod-eling have been used to determine the limitations of low grade timber floor slabs. The experimental work re-vealed that the behaviour of individual low grade timber members subjected to loading are highly unpredict-able due to the presence of excessive defects within the timber. It is concluded that utilizing low grade timber in small slab units in laminated form increases the reliability of the product considerably.
