Abstract

This paper reports on a numerical investigation on the effect of material non-linearities and geometric imperfections on the structural behaviour of hot-rolled 3CR12 columns. A nonlinear finite element model was developed and compared to experimental results to verify the model. The finite element model was then used to investigate the influence of gradual yielding material behaviour, initial geometric imperfections and residual stresses on the resistance of columns. The relevant material properties were obtained experimentally by conducting compression tests. The size and distribution of the residual stresses were determined with the sectioning technique. The numerical results from the finite element analysis were compared to the SABS 0162-1:1993 code of practice concerning the design of hot-rolled steelwork.
