[en] This paper presents numerical and analytical investigations on iron columns under axial compression, strengthened with high modulus carbon fibre reinforced polymer (FRP) sheets. Numerical and analytical models are proposed to predict the resistance and stability load of such elements, including effects of section and member geometrical imperfections and of the nonlinear characteristic and the anisotropy in post elasticity of iron material. It is shown that axial resistance and stiffness of iron columns can be increased significantly with the use of longitudinal FRP sheets as a result of the reduction of the column slenderness, but also that transverse FRP sheets should also be used to avoid any local buckling of the longitudinal FRP sheets during loading.
