# Wide Flange Section

This command allows the user to construct a WFSection2d object, which is an encapsulated fiber representation of a wide flange steel section appropriate for plane frame analysis.

```tcl section WFSection2d $secTag $matTag $d $tw $bf $tf $Nfw $Nff ```

secTag

unique section tag

matTag

tag of uniaxialMaterial assigned to each fiber

d

section depth

tw

web thickness

bf

flange width

tf

flange thickness

Nfw

number of fibers in the web

Nff

number of fibers in each flange

The section dimensions $d, $tw, $bf, and $tf can be found in the AISC steel manual.
