“…More recently, Milch et al (2017) validated some empirical expressions to predict the load-carrying capacity of singleshear dowel-type joints, per shear plane, loaded laterally to their axis as proposed by Fukuyama et al (2008) based on EYM. It can be noted that Eurocode 5 underestimates the resistance of the connections in all cases.…”

“…Moreover, they proposed an investigation of which factors influence the connections' behaviour the most. Milch et al (2017) presented theoretical and experimental approaches to determine the load-carrying capacity for bending and shear deformation of wooden dowels according to design, as proposed by Fukuyama et al (2008). The design method is based on the European yield model (EYM) and aims to predict the load-carrying capacity of single shear dowel-type joints, per shear plane, loaded laterally to its axis.…”

Dowel-type timber joints made of wood are of particular interest for interventions on built heritage because such heritage buildings often involve timber structures. Wooden dowels offer a lower cost when compared with other connectors and conform to the tendency for using wood-based solutions to retrofit timber structures. However, there is a significant lack of information regarding the modelling of these wooden connectors’ responses, in terms of analytical expressions as numerical models. Therefore, this paper presents the results of an extensive experimental campaign of timber-to-timber joints using wooden dowels. Two wood species were considered: chestnut as a hardwood and spruce as a softwood. The wooden dowels were always made of massaranduba, a Brazilian hardwood. The aim of the experimental campaign was to obtain and analyse the response of this type of connection, and then to compare it with the load-carrying capacity accessed through the available analytical expressions to verify its accuracy. The test results highlighted the advantages of using wooden dowels in timber joints. Moreover, it became clear that further analysis and research studies are needed to suggest new expressions that are in accordance with the behaviour of the connection.

“…Instead of the Bernoulli-Euler Beam, the Timoshenko Beam 28 which considers the shear deformation on the Winkler Model, is effective in the cases where the shear deformation of the beam is not negligible in a rather thick beam. Fukuyama et al 46 analyzed the beam on the Winkler Model considering the shear deformation and also friction effects for the wooden dowels in shear joints. This means that they used the Timoshenko Beam on the Winkler Model.…”

This paper reviews recent developments of the mechanical models and formulations for the embedment of traditional timber joints in Japan. In recent decades in Japan, seismic performance evaluation methods of traditional timber buildings have been actively researched, and useful findings have been obtained to evaluate the seismic performances of traditional timber buildings such as temples, shrines, and dwelling houses. The major seismic resisting elements of traditional timber buildings in Japan are restoring forces of thick column rocking, rotational resistances of column‐beam joints, and shear resistances of mud/wood walls. Among them, the restoring force of rotational resistances of column‐beam joints due to embedment plays an important role. Such restoring force characteristics depend primarily on the partial compression on continua. However, the partial compression on continua is difficult to analyze owing to the continua. In relation to the partial compression on continua, research results of beams on elastic foundations are reviewed. Subsequently, the recent developments of mechanical models and formulations of the traditional timber joints in Japan are reviewed and problems related to formulations are discussed, and the authors' comments are given.

“…In historical timber structures, traditional carpentry joints were used, while wooden dowels fixed the mutual position of the elements. Dowels are often used as primary connectors in furniture frames constructed of both solid wood and wood-based composites (Fukuyama et al 2007). However, because wood is hygroscopic, it is common to see the wood dowel become unfastened in the furniture joint.…”

Joints are used to join furniture parts, and they represent a critical part of the structure of furniture. The quality of joints is greatly affected by the accuracy of their execution. When designing furniture, it is important to carefully consider the type of joint used so that it can hold all the joined elements together. Under loading of the joined structures, internal forces develop, which can lead to failure of the joints. This study investigated the elastic stiffness of spruce (Picea abies L.) dowel joints. The effects of selected factors such as the type of loading (compressive versus tensile), the size of the dowels (one-half versus one-third of the thickness of the joined elements), the type of adhesive used (polyvinyl acetate versus polyurethane), and annual ring deflection were examined. Spruce dowel joints exhibited the highest elastic stiffness values with a higher-diameter dowel glued with PUR adhesives and subjected to compressive loading. The impact of annual rings was not a significant factor. Finally, the reference type joints were compared with other commonly used types, such as three types of mortise and tenon joints (simple, haunched, and dovetail).
