This paper presents a description of the repair of timber structures using a prosthesis scarf
joint designed for the replacement of damaged parts of beams. This new scarf joint makes use
of the strutting effect of inclined contact faces where the forces are transmitted through
wooden coupling elements - wooden dowels or keys. The scarf can be modified in four
variants according to the relevant stress and is suitable for historically valuable timber
structures. It meets both functional and aesthetic requirements. The designer - structural
engineer will learn in the methods the load bearing capacity or stiffness of the beam with the
designed joint, its recommended dimensions and detailed geometry. The contractor will
appreciate the description of the execution and maintenance of the joint.
