ABSTRACT
When building with wooden structures, the type of connection is important to achieve high load-bearing capacity with low deformations. In modern practice, many types of connections have been developed, one of them – the connection using nagels is widely used. However, when preparing holes in parts and installing metal nails, gaps occur in the joints. This usually results in an uneven distribution of the load on the connection elements. Conventional approaches to the design and calculation of nagel joints assume an ideal joint structure, i.e. gaps are not considered. In this paper, we consider the effect of the permissible deviation between the pre-drilled hole and the diameter of the pins on the bearing capacity of the joint. The use of self-tapping pins reduces the tolerances to almost zero on all connected elements.
