"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 not pre-drilled nails. 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. The ultimate limit state of the connection is governed by a combination of the plastic deformation of the timber and yielding of the nail forming plastic hinges. After the test the observed local deformations inside of the specimen are shown. Clearly visible are the plastic hinges of the nails and the local plastic deformations in the supporting wood material."
