Abstract: A joint system widely used in the construction of timber structures is based on the use of dowels, which transmit efforts between the timber elements. In these connections, it is attempted to reduce the diameter of the dowel, because large diameters increase the possibility of brittle fracture. In the present work, based on the approach of the European Yield Model that provides the load capacity of the joint, the stress distribution is analyzed in detail and a model is proposed. This model takes into account the slip of the joint and the propagation of the yield areas near the contact surfaces between dowel and timber, as the load increases. An iterative method that links load and slip equations is developed. It also provides information to improve the joint design, especially taking into account its stiffness behaviour. The results obtained from this analytical model have been compared with those from empirical tests of different samples, showing a good agreement.
