Abstract:This paper presents novel full-scale timber multi-layered beams using welded-through wood dowels in place of metallic fasteners, connectors, and the traditional poly(vinyl acetate) (PVAc)-adhesives. Two meter timber four-layer beams are constructed in this fashion with variation of the number of dowels in each. Four-points bending tests were carried out to evaluate to mechanical performances of such beam systems. The practical difficulties encountered in constructing deeper multi-layer beams are discussed and possible solutions which have been employed for the purpose of this work and proved successful are presented.In order to investigate thoroughly the full potential of multi-layered beams with a very limited number of experimental studies, a 3D FE model has been presented, validated against experimental results and then used to study some influential parameters. The results showed that a reasonable bending stiffness of multi-layered beams is achievable with a good combination of material and geometric parameters.
