Abstract(s) :

(Anglais) Current standards mainly focus on modern dowel type joints and usually provide little guidance to designers regarding traditional joints. An effective timber repair needs a complex interdisciplinary work with careful investigation and execution. In the field of restoration of patrimonial buildings, engineers have to work with old structures made of badly preserved timber elements connected by particular connections known as “traditional connections”. The joints play a major role in the structural behaviour of the old timber frames. Further studies in the area are deemed necessary to establish a reliable design specification, the protocol of the repair procedure, and recommendations for the future rehabilitation or strengthening interventions. Patrimonial timber roofs are of considerable historic and aesthetic significance, and demand a thorough understanding of the principles and techniques involved to choose a suitable repair strategy. When restoring a beam with a prosthesis, a continuity joint between the prosthesis and the sound parts of the existing timber beams has to be designed. Those connections are most of the time made with glued-in rods. This paper presents a research carried out to develop a FE model which may predict the behaviour, e.g. the strength and the stiffness, of glued-in rods used for continuity joints.
