Constructs a parallel flange channel (PFC).
Constructs a parallel flange channel (PFC) section with the bottom left corner at the origin
(0, 0)
, with depthd
, widthb
, flange thicknesst_f
, web thicknesst_w
and root radiusr
, usingn_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:
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()
