The paper presents experimental, numerical, and analytical methods for the prediction of the loadbearing capacity of timber connections with metal angle brackets, utilising annular ring nails as fasteners. Full-scale testing experiments were performed in order to obtain the stiffness of the connection. Numerical simulations are employed to predict the load-bearing capacity of the angle brackets, when the external force is in the direction of the opening of the angle bracket. The characteristic load-bearing capacity of the connection was calculated using both the results of the numerical simulation, and analytical formulas, utilising laboratory measurements of the timber density. The paper presents the results of the three approaches, allowing direct comparison of the veracity of the simulations.
