The subject of this paper is a formulation and discussion about an adhesive joint model in cases of reinforcement or reconstruction of weakened cross-sections of wooden elements. The problem is modeled within the linear theory of elasticity as a plane stress case. It is assumed that wood is an orthotropic material. Reinforcement is achieved by attaching a covering plate, and reconstruction by introduction of an insert at a weakened (deteriorated) zone of the element. Analysis of the influence of covering plates and insert thickness on the stress state in adhesive and in adherends is carried out. Elements subjected to bending moments or bending moments with shear forces are considered.
