Constructs an I1 section.

Constructs an I1 section with the web’s middle center at the origin (0, 0), with four parameters defining dimensions.

Parameters:

  • dim_1 (float) – Twice distance from web end to flange end

  • dim_2 (float) – Thickness of web

  • dim_3 (float) – Length of web (spacing between flanges)

  • dim_4 (float) – Depth (y) of the I1-section

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

Returns:

I1 section geometry

Return type:

Geometry

Example

The following example creates an I1 cross-section with a depth of 5.0 and width of 1.75:

from sectionproperties.pre.library import nastran_i1

nastran_i1(dim_1=1.0, dim_2=0.75, dim_3=4.0, dim_4=5.0).plot_geometry()
