“…A característica da curva de cada corpo de prova do grupo Encaixe C30 mostra que a falência da ligação por encaixe ocorre com a flexão do pino. Após a primeira ruptura, salientada com seta em vermelho na Figura 6, o comportamento da madeira é seguido pela compressão perpendicular às fibras, caracterizado pelo aumento de resistência e aumento considerável da deformação, este comportamento é esperado para encaixes do tipo retangular [26]. Em seguida, a ligação é acompanhada de múltiplas fraturas, sendo considerado como falência da ligação o momento da primeira ruptura, conforme indicado pela seta em vermelho.…”

RESUMO Em estruturas de wood frame, as ligações entre montantes e banzos tem como finalidade garantir a rigidez e o contraventamento necessários para essas construções, que são naturalmente flexíveis, quando submetidas aos esforços horizontais tais como vento e sismos. Este trabalho teve como objetivo avaliar a resistência ao cisalhamento de ligações de madeira para produção de painel de wood frame produzidos com madeira de eucalipto jovem (menos que 15 anos de idade), tendo em vista que o plantio de espécies desse gênero é mais abundante no país. Os tipos de ligações escolhidas para este estudo foram do tipo chapa de dente estampado, parafuso autoatarraxante e encaixe de madeira. Para cumprir esse objetivo, foram utilizados corpos de prova de madeira de Eucalyptus pellita com idade variando entre 7 e 10 anos (classe C20). Foram utilizados os procedimentos experimentais previstos no projeto de revisão de norma da ABNT PN 02:126.10-001-4 (ABNT, 2017). Os resultados indicaram que a ligação do tipo encaixe é a mais apropriada para a ligação entre banzos e montantes de painéis de wood frame produzidos com madeira de eucalipto jovem, por ter melhor resistência e maior rigidez ao cisalhamento quando comparada com as ligações com parafuso autoatarraxante à 90° e chapa de dente estampado.

“…Mortise-and-tenon jointing, a time-honored construction technique, has been widely used to produce complex wooden architectures from simple building blocks (Figure a). The use of mortise-and-tenon joints as nodes between the individual construction units allows the preparation of elaborate frameworks that are not only able to bear large loads but also tolerate a degree of deformation . On the molecular level, we speculated that the use of mortise-and-tenon jointing might give rise to stable 3D crystalline organic frameworks with good mechanical and porosity features.…”

Three-dimensional (3D) crystalline organic frameworks with complex topologies, high surface area, and low densities afford a variety of application prospects. However, the design and construction of these frameworks have been largely limited to systems containing polyhedron-shaped building blocks or those relying on component interpenetration. Here, we report the synthesis of a 3D crystalline organic framework based on molecular mortise-and-tenon jointing. This new material takes advantage of tetra(4-pyridylphenyl)ethylene and chlorinated bis(benzodioxaborole)benzene as building blocks and is driven by dative B−N bonds. A single-crystal X-ray diffraction analysis of the framework reveals the presence of twodimensional (2D) layers with helical channels that are formed presumably during the boron−nitrogen coordination process. The protrusion of dichlorobenzene units from the upper and lower surfaces of the 2D layers facilitates the key mortise-and-tenon connections. These connections enable the interlocking of adjacent layers and the stabilization of an overall 3D framework. The resulting framework is endowed with high porosity and attractive mechanical properties, rendering it potentially suitable for the removal of impurities from acetylene.

“…Throughout the years, the compilation of research for mortise and tenon was evolved accordingly; such as the study of design considerations for mortise and tenon connections [3]- [4]; experimental performance of mortise and tenon connections in green Oak [5]- [6]; shear and bending of mortise and tenon performance for Kempas [7]- [9] and mechanical performance of mortise and tenon joints pre-reinforced with slot-in bamboo scrimber plates [10].…”

Kapur (Dryobalanops spp.) is one of the Malaysian common species used for structural construction material. It is capable of serving as a beam and column. This study focused on the experimental mortise and tenon connection fastened with wood; glass fibre reinforced polymer (GFRP), and steel dowel. The finite element method (FEM) was used to model the behaviour of mortise and tenon joint for wood dowel subjected to pull-out loads using ABAQUS software. The experimental results were used to validate a three dimensional finite element model of mortise and tenon joint. The full structural scale ofmortise and tenon was fastened with a 21 mm diameter dowel. The investigation was carried out by applying tensile loads to the top of the tenon. This study adopted a linear elastic orthotropic material to represent the Kapur wood behaviour using the FEM. In this study, the results reveal the load carrying capacity of the mortise and tenon in a sequence of highest to the lowest is when the joint dowelled with GFRP, steel and wood. The stiffness value obtained from the FEM for wood dowel is found higher than the experimental value. Thus, the findings from finite element method (FEM) and the experimental results both had slightly dissimilar load–displacement curve shape. However, this study contributes to a better knowledge of mortise and tenon performance when secured with a wood dowel.
