Abstract (EN): The prediction of the behaviour of joints relies on experimental and numerical tests that provide accurate information for the characterization of the various joint components. This paper presents the calibration and validation of a parametric FE model of a beam-to-column double extended end-plate steel joint, using test results, and characterizes the web panel components using the validated FE models. The model implemented in the ABAQUS FE package which takes into account the non-linear geometrical and material behaviour, non-linear contact and slip. The calibration/validation of the model is based on results from an experimental research programme on three double-extended end-plate partial-strength beam-to-column joints. The behaviour of the joints is characterized both globally and in terms of the critical components. The experimental and numerical results are compared, revealing good agreement, allowing their further use in the more detailed components assessment. Thus, based on the validated stress and deformation fields of FE results, a procedure is proposed to extract the force-deformation behaviour of the column web components. The results are compared with those obtained from Eurocode 3 and from the literature.
