Nonlinear, three dimensional FE analysis of axial compression, was conducted using the finite element program ABAQUS. The numerical results were validated through comparison with experimental data in terms of ultimate loading and deformation modes. Modeling related problems such as the definition of boundary conditions, imperfections, concrete-steel interaction, material representation and others are investigated using a comprehensive parametric study. The developed FE models will be used for an enhanced interpretation of experiments and for the predictive study of cases not included in the experimental testing.}, type={Artykuły / Articles}, title={Numeryczne modelowanie zespolonych słupów stalowo-betonowych}, title={Finite element modeling of composite concrete-steel columns}, URL={http://journals.pan.pl/Content/83788/mainfile.pdf}, keywords={concrete-filled battened steel columns, composite columns, finite element analysis}, }
