Abstract

A finite element model is described in this paper, which investigates the behaviour of CFS built-up channel columns, connected back-to-back with the help of intermediate web fasteners, subjected to axial load. Finite element package ABAQUS was used to develop the finite element models for built-up columns, which were verified against the test results reported by the authors. Non-linearities of materials and initial imperfections were included in the FEA model. Axial capacity, deformation patterns and load–displacement behaviour were reported from the FE analyses and validated against the test results, reported by the authors in another paper. Axial strengths obtained from the FEA modes were verified against the AISI and AS/NZS design strengths, for CFS built-up columns; obtained comparisons showed that AISI and AS/NZS standards were un-conservative for stub and short columns which failed by local buckling, whereas standards were over-safe for columns failed through overall buckling.
