Buckling Behaviour of Hollow Flange Channel Beam Sections in Bending
Abstract The hollow flange beams are designed to take the advantages of hot-rolled steel sections in which area is concentrated away from the neutral axis and the ease of installation associated with cold-formed sections. The present study deals with the flexural behaviour of hollow flange channel beams sections by Finite Element modeling using the general purpose finite element software ABAQUS. A Parametric study is carried out by varying the flat width/thickness ratio, depth of the beam, depth of the hollow flange and length of the beam. The effects of distortional buckling on hollow flange channel beam are studied and finite element model results are compared with AS/NZS 4600:2005 code for cold-formed steel structures. It is found that code based design is economic for hollow flange beams which fail in lateral distortional buckling alone.
