Constructs a tapered flange channel section.

Constructs a tapered flange channel section with the bottom left corner at the origin (0, 0), with depth d, width b, mid-flange thickness t_f, web thickness t_w, root radius r_r, flange radius r_f and flange angle alpha, using n_r points to construct the radii.

Parameters:

• d (float) – Depth of the tapered flange channel section

• b (float) – Width of the tapered flange channel section

• t_f (float) – Mid-flange thickness of the tapered flange channel section (measured at the point equidistant from the face of the web to the edge of the flange)

• t_w (float) – Web thickness of the tapered flange channel section

• r_r (float) – Root radius of the tapered flange channel section

• r_f (float) – Flange radius of the tapered flange channel section

• alpha (float) – Flange angle of the tapered flange channel section in degrees

• n_r (int) – Number of points discretising the radii

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

Returns:

Example

The following example creates a tapered flange channel section with a depth of 10 in, a width of 3.5 in, a mid-flange thickness of 0.575 in, a web thickness of 0.475 in, a root radius of 0.575 in, a flange radius of 0.4 in and a flange angle of 8°, using 16 points to discretise the radii:

from sectionproperties.pre.library import tapered_flange_channel

tapered_flange_channel(
    d=10, b=3.5, t_f=0.575, t_w=0.475, r_r=0.575, r_f=0.4, alpha=8, n_r=16
