[en] The prediction of the shear resistance of connections as presently given in Eurocode 3, Part 1-8, cannot be applied in a straightforward way to the connection for tubular racking structures realized by means of long through bolts. In order to verify the possibility to extend the codified approach to such joint configurations, in the present paper a finite element model with three-dimensional solid elements is established investigating the behaviour of the connections under shear load in a wide range of variability of the geometrical parameters. The validation of the numerical model has been performed starting from the results of experimental tests already performed by the authors at the laboratory on Materials and Structures of the University of Liège. Based on the finite element results, the load displacement curves for all the assemblies were successfully predicted evidencing the important role played by the hole’s geometry and reduced diameter of the bolts on the initial stiffness of the connections. The results of a parametric study by means of a calibrated FE model in Abaqus/CAE allowed to verify the possibility to extend the formulations provided by EC3 for predicting the bearing resistance of plates to these kind of connections and to analyse the influence of the main parameters governing the bearing resistance: the distance e1 between the hole and the edge of the tube, the distance e2 between the hole and the lateral edge of the plate composing the tube section and the thickness t of the tube.
