Glued-in rods are to be considered a main research field within timber engineering. While there are still many open questions, significant progress has been achieved with regard to steel bars embedded in softwoods. This paper ambition is extending the knowledge about glued-in rods towards hardwood and hardwood laminated veneer lumber, respectively, towards the use of G-FRP bars therein. For that purpose, an extensive experimental campaign was documented, starting from the extensive characterization of the timber, adhesive, small scale specimens to identify suitable adhesive, and concluded by full-scale specimen tests. The study will allow, by providing a coherent set of material parameters, for hardwood, a much better comparison of existing joint capacity methods of previously developed for softwood.
