dc.description.abstractThis work focuses mainly on the resistance of members to flexural buckling according to Eurocode 3. The work provides the mathematical backgrounds to the equations and buckling curves presented in Eurocode 3. The work also attempts to reveal how material behavior and residual stress influence the flexural buckling resistance which is demonstrated through finite element (FE) simulations. The work presents modeling and analysis on hollow section columns in ABAQUS 6.14. Linear and non-linear buckling analyses of the hollow section columns, with the imperfections, are implemented in this work. Specifically, the imperfections considered in this study are material plasticity, initial bow and residual stress. It was found that mesh size influences buckling behavior. Elastic-plastic with a strain hardening slope of E/100 gives a little higher buckling load but did not significantly affect the results. Residual stresses influence buckling behavior. Both material behavior and residual stresses influence reduce when the column heights increases. The rectangular section has high buckling curve than that of square section with same slenderness ratio. The minor axis have high buckling curve when the ratio of height to width(h/b) of cross sections high but the major axis buckling have the same buckling curves given in Eurocode 3.en_US
