Classes:

• IProfile –

  Representation of I shaped profiles.

Bases: Profile

Representation of I shaped profiles.

For standard profiles, use the specific standard profile class like HEA, HEB, HEM or IPE. For example,

hea_profile = HEA.HEA200

Attributes:

• top_flange_width (MM) –

  The width of the top flange [mm].

• top_flange_thickness (MM) –

  The thickness of the top flange [mm].

• bottom_flange_width (MM) –

  The width of the bottom flange [mm].

• bottom_flange_thickness (MM) –

  The thickness of the bottom flange [mm].

• total_height (MM) –

  The total height of the profile [mm].

• web_thickness (MM) –

  The thickness of the web [mm].

• top_radius (MM) –

  The radius of the curved corners of the top flange.

• bottom_radius (MM) –

  The radius of the curved corners of the bottom flange.

• name (str) –

  The name of the profile. Default is "I-Profile". If corrosion is applied, the name will include the corrosion value.

• plotter (Callable[[Profile], Figure]) –

  The plotter function to visualize the profile (default: plot_shapes).

structural_sections.steel.profile_definitions.i_profile.IProfile.with_corrosion

with_corrosion(corrosion: MM = 0) -> IProfile

Apply corrosion to the I-profile and return a new I-profile instance.

The name attribute of the new instance will be updated to reflect the total corrosion applied including any previous corrosion indicated in the original name.

Parameters:

• corrosion (MM, default: 0 ) –

  Corrosion per side (default is 0).

Returns:

• IProfile –

  A new I-profile instance with the applied corrosion.

Raises:

• ValueError –

  If the profile has fully corroded.
