Abstract

In order to study the bearing capacity and stability behavior of cold-formed steel flexural members with complicated sections, a total of 12 specimens divided into 6 groups were tested, including 3 groups of pure bending tests and non-pure bending tests each. There were three types of sections considered in this investigation, including channels with complex edge stiffeners (called B1-section), Σ section with complex edge stiffeners (called B2-section), and channels with complex edge stiffeners and V-type web stiffeners (called B3-section). Local buckling, distortional buckling and interaction buckling between them were observed in tests. The experimental results indicate that the bending strengths of B2-section specimens were the largest of these three types of specimens under the same conditions. It is found that the bending strength of B2-section specimens was increased by 6.47% for pure bending state and 8.12% for non-pure bending state, compared with that of B1-section specimens. Bending strength of B3-section specimens was almost the same with that of B1-section specimens under pure bending, but a little smaller than that of B1-section under non-pure bending state. It is also shown that B2-section specimens have better plastic deformation behavior than the other two sections. In addition, a non-linear finite element model was presented and verified against tests. The finite element analysis results agree well with experimental bending strength and failure modes.
