Shear Bolted Connections : Numerical Model for a Ductile Component, the Plate-Bolt Bearing

In order to achieve a fill! plastic distribution of forces in a shear bolted connection, ductility is
required to the steel plate and to the [JltII€<b0lI contact zone in the firstly loaded bah rows, Knowing t/1at bolts present a brittle behavior, deformation capacity has to be obtained front ductile components as the plate-bolt in bearing. In the present paper a numerical model is proposed to evaluate the plate-bolt in bearing component. The main objective is not only to achieve it elastically but to obtain a good approximation of the post-elastic response. The proposed model has been successfully validated hv €.\p£'I‘iNtellt£1l tests on shear bolted connections petjformed at the Delft University of Technology and at the University of Ljubljana. The EC 3 Part 1.8 [1] approach, to evaluate resistance and initial stiflitess of the plate—bolt in bearing component, is included in the comparison and discussion ofresttlts.
