| dc.description.abstract | In this work the analysis of the post-buckling state in the elasto-plastic range of a box-colunm subjected to uniform compression in the elasto-plastic range is preseoted. The problem is investigated using Rayleigh-Ritz variational method. The stress-strains relations in the plastic range are determined on the basis of the flow theory of plasticity. The proposed method is a combination of analytical and numerical solutions. Different materiał stress-strain curves and initial imperfections such: out-of-flatness and residual stresses are taken into account. The load-shortening curves for column of different geometrical parameters and material properties are shown in diagrams. | en_EN |
