Behaviour of steel end plate bolted beam-to-column joints

This paper presents a numerical investigation into moment-rotation behaviour of extended, flush, and partial depth end-plate joints. Two types of steel beam-to-column joints are modelled: I-beam (IPE) to H-column (HEB) and PFC-beam (UPE) to SHS-column. The joints are designed as a single cantilever beam-to-column joint configuration. The connection details are in accordance with Eurocode 3 part 1-8 and SCI guides P358 (Simple joints) and P398 (Moment joints). Three-dimensional finite element modelling of the joints is car-ried out using ABAQUS. The numerical results are validated against experiments. Both material and geo-metric nonlinearities are considered. All joints are classified according to their stiffness as per Eurocode 3. The failure modes of different joint configurations are determined and compared with the experiments. The key contribution of this paper comes from stiffness analysis of the joints, characterisation of the joints as per EC3 and modelling nonlinear behaviour of the joints.
