One of the problems with the construction of wooden structures is making an effective joint. Currently, most of the joints used are mechanical. There are three basic drawbacks to these types of joints: low load capacity, reduced stiffness promoting joint displacement, increasing structural deformity and vulnerability in the event of a fire. So, the use of adhesives to make joints is one of the most interesting fields for future development. Generally, in the field of adhesive joints, joints made with glued-in rods are a solution of great interest and possibilities. Joints made with glued-in rods provide clear advantages summarized as: high load capacity; stiff joints without displacement under load conditions; hidden joints, thus, the actual timber protects the structure from fires. Furthermore, hidden joints confer joints of aesthetic simplicity unifying the different elements of the structure.
