Add to ORKGA mechanical model capable to predict the local buckling of pultruded FRP thin-walled beams and columns, taking into account the shear deformability of composite materials, is presented in this paper. The model is based on the individual analysis of buckling of the components of FRP profile, assumed as elastically restrained transversely isotropic plates. The analysis is developed within the field of small strains and moderate rotations.</p
