“The aim of the TimBoost project is to develop fully validated software to design connections with glued-in rods (GIR) in timber structures."
The design rules used in this software will be based on theoretical, experimental and numerical research, as well as an extensive literature study. Using the software, the resistance of a GIR connection can be determined for the different possible failure modes. It will be easy to quickly check how the connection resistance is modified by changing the connection geometry, member properties, rod geometry and arrangement, as well as the adhesive properties.

Glued-in rods (GIR) joints provide many advantages in timber joints, including lower weight, greater strength and stiffness, improved aesthetics and good fire resistance. Despite providing practical solutions for both new and for strengthening existing timber structures, GIR joints are not used as much as they should in practice because of lack of standards, adequate information on the design and quality control of installation methods.
