Cyclic modelling of steel beam-to-column extended end plate joints

In this work the modelling of the rotational cyclic behaviour of steel extended end plate joints is examined by using a mechanical model based on the so called component approach. In order to extend the component approach to the prediction of the rotational behaviour of partial strenght joints it is necessary to define the cyclic constitutive laws of the single components. Starting from the results of previous studies of the authors concerning the cyclic behaviour of bolted T-stubs, which allow to model some important joint components, such as the column flange in bending and the end plate in bending, and using the studies available in technical literature with reference to the cyclic behaviour of the column web panel in shear, in tension and compression, in this work a model is introduced for the prevision of the cyclic behaviour of the whole extended end-plate joints, validated by means of the experimental tests performed at the laboratory of materials and structures of the University of Salerno.
