d (float) – Depth of the tapered flange I section
b (float) – Width of the tapered flange I section
t_f (float) – Mid-flange thickness of the tapered flange I 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 I section
r_r (float) – Root radius of the tapered flange I section
r_f (float) – Flange radius of the tapered flange I section
alpha (float) – Flange angle of the tapered flange I section in degrees
n_r (int) – Number of points discretising the radii
material (Material) – Material to associate with this geometry

Example
The following example creates a tapered flange I section with a depth of 588 mm, a width of 191 mm, a mid-flange thickness of 27.2 mm, a web thickness of 15.2 mm, a root radius of 17.8 mm, a flange radius of 8.9 mm and a flange angle of 8°, using 16 points to discretise the radii:
from sectionproperties.pre.library import tapered_flange_i_section tapered_flange_i_section( d=588, b=191, t_f=27.2, t_w=15.2, r_r=17.8, r_f=8.9, alpha=8, n_r=16 ).plot_geometry()
