Abstract [en]

Mechanical connections in wood structures typically consist of structural members connected with combination of thin-walled steel angle brackets and fasteners in forms of nails or screws. Design of these steel connectors is typically based on short-term load bearing capacities. Observations from experimental testing indicate that both the angle bracket and the fasteners possess properties such the connections can be designed to behave in a ductile manner. This paper presents numerical simulations of ductile angle bracket connections calibrated against experimental results and subsequently validated. Special focus is on single nail behaviour when the jointed timber members are subjected to cyclic loading. Simulations of global behaviour of connections show that acceptable match between the simulation and the experimental results can be achieved despite relatively simple nail model is used for both loading and unloading behaviour.
