Constructs Nastran’s I section.

Constructs Nastran’s I section with the bottom flange’s middle center at the origin (0, 0), with six parameters defining dimensions.

Parameters:

• dim_1 (float) – Depth(y) of the I Section

• dim_2 (float) – Width (x) of bottom flange

• dim_3 (float) – Width (x) of top flange

• dim_4 (float) – Thickness of web

• dim_5 (float) – Thickness of bottom web

• dim_6 (float) – Thickness of top web

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

Returns:

I section geometry

Return type:

Geometry

Example

The following example creates an I cross-section with a depth of 5.0:

from sectionproperties.pre.library import nastran_i

nastran_i(
    dim_1=5.0, dim_2=2.0, dim_3=3.0, dim_4=0.25, dim_5=0.375, dim_6=0.5
).plot_geometry()
