Development of non-metallic timber connections for contemporary applications

Non-metallic timber connections have the advantage of improved fire safety and corrosion resistance over mechanically fastened metallic connections. Currently mainstream, contemporary non-metallic connections are typically constrained to the form of glued connections. However, glued connections require strict quality control, which adds expense and requires off site prefabrication. This has restricted the exploitation of the benefits of non-metallic connections. This paper presents findings from a programme of research investigating the structural performance and analysis of non-metallic dowel and plate materials to provide mechanically fastened connections for contemporary timber structures. Particular focus is given to the use of glass fibre reinforced plastic (GFRP) dowels and densified veneer wood (DVW) plates.
