ABSTRACT
The design of cold-formed members in compression is generally more complex than conventional hot-rolled steel members. This is a result of the additional modes of buckling deformation which commonly occur in thin-walled structural members. These are
(a) Local buckling and post-local buckling of stiffened and unstiffened compression elements, as described in Chapter 4
(b) Flexural, torsional, and torsional-flexural modes of buckling of the whole compression member as shown in Figure 1.13b.
