Constructs a parallel flange channel (PFC).

Constructs a parallel flange channel (PFC) section with the bottom left corner at the origin (0, 0), with depth d, width b, flange thickness t_f, web thickness t_w and root radius r, using n_r points to construct the root radius.

Parameters:

  • d (float) – Depth of the PFC section

  • b (float) – Width of the PFC section

  • t_f (float) – Flange thickness of the PFC section

  • t_w (float) – Web thickness of the PFC section

  • r (float) – Root radius of the PFC section

  • n_r (int) – Number of points discretising the root radius

  • material (Material) – Material to associate with this geometry

Returns:

Parallel flange channel section geometry

Return type:

Geometry

Example

The following example creates a PFC section with a depth of 250 mm, a width of 90 mm, a flange thickness of 15 mm, a web thickness of 8 mm and a root radius of 12 mm, using 8 points to discretise the root radius:

from sectionproperties.pre.library import channel_section

channel_section(d=250, b=90, t_f=15, t_w=8, r=12, n_r=8).plot_geometry()
