Joints are essential parts of timber structures providing force transfer between structural timber part and providing ductility in case of extreme actions. Joining of timber members is typically realised by means of steel fasteners, such as nails, screws bolts and dowels. By arranging the fasteners perpendicular to the transferred load, shear connections are formed. In this type of connections, the fasteners are supported and fixed by the wood material, ideally allowing for the formation of ductile yield mechanisms in the steel fasteners. This video shows a tensile testing of a double shear timber-to-timber joint with single sided toothed-plate connectors. At the beginning, the set-up of the experiment is shown. Parallel to the test progress the corresponding load-deformation curve of the joint is drawn. In a joint with a single-sided toothed plate, the load is passed by embedment stresses from the member into the teeth of the connector. Then the load is passed directly to the bolt and also by bearing of the member in the bolt due to embedment slip at the connector teeth. The ultimate limit state of the connection is governed by a combination of the plastic deformation of the timber and yielding of the bolt forming plastic hinges. After the test the observed local deformations inside of the specimen are shown. Clearly visible are the plastic hinges of the bol and the local plastic deformations in the supporting wood material."
