Abstract (EN): In this paper a detailed FE model of a bolted steel beam-to-column end-plate connection developed in ABAQUS is presented. The model is capable of simulating the behaviour of partial-strength joints subjected to both monotonic and cyclic loading. The model is validated by comparing the numerical results with available experimental data and also with results derived with simpler 2D models. The modelling approach is then employed to undertake extensive non-linear time history analyses on a set of partial-strength joints using several earthquake records and considering increasing levels of ductility demand, for a range of connections capable of representing the behaviour of the three ductile failure modes defined in Eurocode 3. Relationships between ductility and equivalent viscous damping are determined, which can be used in the application of the Direct Displacement-Based Design procedure to the seismic design of steel moment resisting framed structures with partial-strength connections.
