Among the different methods for strengthening reinforced concrete (RC) columns, steel caging is one of the most extensively used for square or rectangular cross-section columns. Based on the results of a series of experimental studies, this paper shows some finite element models of steel-caged RC columns. Three cases are modelled: isolate strengthened RC columns under axial loads; the performance of the strengthened RC column under axial loads, taking into account the beam-column joint area; and, the strengthened RC column and the beam-column joint area, when the column is subjected to bending moments and axial loads. From each finite element model, a parametric study is carried out, with the aim of investigating the influence of several parameters, related both to the steel cage and to the RC column itself.
