摘要：The article presents the derivation of the resolving equations for calculating concrete filled steel tubular columns with an annular cross-section under central compression, taking into account physical nonlinearity. The solution is performed numerically by the finite difference method. The deformation theory of plasticity of concrete by G.A. Geniev is used as the law of deformation
