DESIGN PRINCIPLES FOR COLD-FORMED<br />

STEEL SHAPES<br />

The structural behavior of cold-formed shapes follows the same laws of structural<br />

mechanics as does that of conventional structural-steel shapes <strong>and</strong> plates. Thus,<br />

design procedures commonly used in the selection of hot-rolled shapes are generally<br />

applicable to cold-formed sections. Although only a portion of a section, in some<br />

cases, may be considered structurally effective, computation of the structural properties<br />

of the effective option follows conventional procedure.<br />

8.4 SOME BASIC CONCEPTS OF COLD-FORMED<br />

STEEL DESIGN<br />

The uniform thickness of most cold-formed sections, <strong>and</strong> the fact that the widths<br />

of the various elements composing such a section are usually large relative to the
