“…Aira et al [13] experimentally analyze the structural behavior of halved and tenoned scarf joint subjected to tensile stresses in order to describe the different failure modes. In Perria et al [14] results of an experimental campaign and an analytical model for the behavior of the halved under-squinted scarf joint are presented. Different aspects that influence the behavior of the connection subjected to pure compression, pure bending and combined compression and bending are analyzed.…”

Repairing stop-splayed scarf-joints in beams or truss-rods is a frequent occurrence in restoring ancient timber structures. Reinforcement of carpentry joints by means of metallic elements as well as unconventional materials is extensively investigated in literature, while timber pegs in timber to timber connections are studied referring mainly to new timber structures. In the present paper, authors' previous research analysing the mechanical behaviour of stopsplayed scarf joints reinforced with timber pegs has been carried on, focusing on the evaluation of ductility which can be achieved by reinforcement with timber pegs. Moreover, the role of slenderness, the rate between jointed timber thickness and peg diameter is analysed. An experimental program has been carried out testing in axial tension two samples of fir scarf joints with an ash key: one sample constituted of two simple scarf joints, and one constituted of three scarf joints reinforced with two ash pegs of 20 mm of diameter. Comparing experimental results has allowed to better understand the role played by timber pegs in reinforcement and to evaluate the influence of reinforcement on ductility of reinforced scarf joints behaviour. Experimental results have also been compared with those obtained in a previous experimental study where an analogous experimental program has been made on smaller scarf joints reinforced with two ash pegs of 8 mm of diameter. So, the role played by slenderness has been focused. The evaluation of the attained results, even if not exhaustive for a reliable theoretical formulation of timber peg behaviour in reinforcing stop-splayed joints, has allowed the identification of some interesting features, that is stiffness and reinforcement due to timber pegs.

This paper is a general description of the state-of-the-art on the European and colonial building techniques found in wooden buildings that currently exist. The description of the use and diffusion of the wooden structures is made by a brief explanation of the relative structural systems, as well as the peculiarities of the elements that compose it, its operating principles, the points of weakness and the joints used. Thus, the English and German techniques of structural timber frameworks are described in detail. On the other hand, other structural techniques and their evolution are presented through a review of works and documents that describe them accurately.
