“…The structural model dealing with the load bearing capacity and the numerical model specifying the stiffness were verified using the experimental results [51], [52] and, subsequently, the models were applied to create diagrams of load bearing capacity, or to derive formulas for deflection (stiffness). The method itself does not introduce any design safety; it shows the results corresponding to the end of the linear area of the joint behaviour in the experiments and models.…”

ii This method is intended for the administrators of historical buildings, designers and workers, and organizations performing repairs of timber members and structures of historical buildings in order to ensure high quality of the preparation and execution of works for the preservation, long-term sustainability, high reliability, and safety of wooden structures. Opponents AbstractThis 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.

“…It was shown that a higher number of dowels affected the beam stiffness more than the ultimate load. FEM and the boundary element method (BEM) are the most popular numerical methods in the research of wooden joints, they are illustrated in reviews of numerical models of joints ranging between the years 1990 to 2015 [13][14][15]. In terms of dowel joints, there are many FE techniques implemented in software that an analyst can currently use, within which there are four basic model categories -solid bolt, coupled bolt, spider bolt and no-bolt [16][17][18].…”

“…There is decidedly less research under way on flexural joints. Moreover, all researchers who have undertaken research on flexural joints (in the Czech Republic [38][39][40][41][42][43][44][45][46][47][48][49][50], United Kingdom [51] or Germany [16,17]) underscore the fact that research is still needed to enable an adequate Fig. 2 a Sketches presenting splice and scarf joints in wooden beams by Leonardo da Vinci [18], b sketches by Leon Battista Alberti [19], c drawing of a stop-splayed scarf joint with dimensions taken from an existing structure based on [11], d model of a composite beam from the fourteenth century palace in Verona [15] description of the static behaviour of joints and to propose the most beneficial repair or strengthening methods for these joints.…”

This paper summarises the current state of knowledge related to scarf and splice carpentry joints in flexural elements, also providing some examples of tensile joints. Descriptions and characteristics of these types of joints found in historical buildings are presented. In addition, issues related to forming carpentry joints in historic and heritage structures are discussed. Next, analyses and studies of flexural elements as well as selected examples of tensile joints described in the literature are presented. It is worth noting that authors of vast majority of the publications cited draw attention to the need for further research in this area. They acknowledge that existing descriptions are incomplete and insufficient for bringing about precise understanding and correct description of the static behaviour of these joints. Knowledge about designing and assessing static behaviour of existing carpentry joints is an important issue and is necessary to properly design and strengthen existing joints in historical timber structures.
