Abstract
The paper concerns the formulation and analysis of an adhesive joint model, aimed at reinforcing or reconstructing weakened wooden elements. The joint is modeled as a plane stress problem of the theory of elasticity. It is assumed that wood is an orthotropic material. The reinforcement of an element is achieved by means of attaching a covering plate, while reconstruction is carried out by introducting an insert into the weakened (deteriorated) zone of an element. The influence of varying thickness of plates and inserts on the stress states in the adherends and adhesive is analyzed. The analyses are related to axially loaded elements.
