ABSTRACT
The description of a structure through a static model is of importance in a scientific field, for many applications in the structural analysis. The analysis of structures shall be carried out using static models which consider to an acceptable level of accuracy the behaviour of the structure and of the supports. The description of carpentry connections through a static model is of importance in a scientific field for the knowledge of the mechanical behaviour of old constructional systems and many applications in the structural analysis with the aim of reinforce and restoration of old timber structures. To properly understand the behaviour of old timber frames, the understanding of the influence of the connections is of importance. The halved undersquinted scarf is a peculiar carpentry connection used in timber frame structures and roofs. Halved refers to the cut of the horizontal surface, that is in correspondence of the half of the timber cross section.
