Abstract | ABSTRACT: The numerical analysis and design of cold-formed steel compression members of oval hollow
sections have been investigated. A finite element model was developed to simulate the existing tests on fixedended
columns of oval hollowsections.The failure modes observed from the tests included material yielding, local
buckling and flexural buckling as well as interaction of local and flexural buckling. The finite element model was
developed using ABAQUS. The material non-linearities obtained from tensile coupon tests as well as the initial
local and overall geometric imperfections were incorporated in the model. Convergence study was performed to
obtain the optimized mesh density. A parametric study included 100 columns was conducted using the verified
numerical model. The experimental column strengths and numerical results predicted by the parametric study
were compared with the design strengths calculated using the current North American, Australian/New Zealand
and European specifications for cold-formed steel structures. In addition, the direct strength method, which was
developed for cold-formed carbon steel members for certain qualified cross sections, was also used to predict
the design strengths for the oval hollow sections. |
