Generic structural section dimensions.

Each variant carries the dimensions the corresponding source entity declares, including the optional fillet radii, edge radii and flange slopes. Those optionals are not decoration: for a rolled steel section the root fillet is a large share of the cross-sectional area, so discarding it yields a section whose area, second moment and mass are all wrong while still looking like the right shape.

Angles are radians, lengths are model units. None means the source did not state the value, which is distinct from stating zero.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

I

Symmetric I section: equal top and bottom flanges.

Fields

depth: Scalar

width: Scalar

web_thickness: Scalar

flange_thickness: Scalar

fillet_radius: Option<Scalar>

Web-to-flange root fillet.

flange_edge_radius: Option<Scalar>

Radius at the flange toe.

flange_slope: Option<Scalar>

Flange taper, radians from the horizontal.

AsymmetricI

I section with independent top and bottom flanges.

Separate from I because collapsing the two flange widths into one silently symmetrises the section: the shape stays plausible while the neutral axis, and therefore every bending result, moves.

Fields

depth: Scalar

web_thickness: Scalar

bottom_flange_width: Scalar

bottom_flange_thickness: Scalar

bottom_fillet_radius: Option<Scalar>

bottom_flange_edge_radius: Option<Scalar>

bottom_flange_slope: Option<Scalar>

top_flange_width: Scalar

top_flange_thickness: Option<Scalar>

Defaults to the bottom thickness when absent.

top_fillet_radius: Option<Scalar>

top_flange_edge_radius: Option<Scalar>

top_flange_slope: Option<Scalar>

L

L or angle section.

Fields

depth: Scalar

width: Option<Scalar>

Defaults to the depth when absent, giving an equal angle.

thickness: Scalar

fillet_radius: Option<Scalar>

edge_radius: Option<Scalar>

leg_slope: Option<Scalar>

Leg taper, radians.

T

T section.

Fields

depth: Scalar

flange_width: Scalar

web_thickness: Scalar

flange_thickness: Scalar

fillet_radius: Option<Scalar>

flange_edge_radius: Option<Scalar>

web_edge_radius: Option<Scalar>

web_slope: Option<Scalar>

flange_slope: Option<Scalar>

U

U or channel section.

Fields

depth: Scalar

flange_width: Scalar

web_thickness: Scalar

flange_thickness: Scalar

fillet_radius: Option<Scalar>

edge_radius: Option<Scalar>

flange_slope: Option<Scalar>

C

C or lipped-channel section.

Fields

depth: Scalar

width: Scalar

wall_thickness: Scalar

girth: Scalar

Length of the returned lip.

internal_fillet_radius: Option<Scalar>

Z

Z section.

Fields

depth: Scalar

flange_width: Scalar

web_thickness: Scalar

flange_thickness: Scalar

fillet_radius: Option<Scalar>

edge_radius: Option<Scalar>

Trapezium

Trapezium.

Fields

bottom_x: Scalar

top_x: Scalar

y: Scalar

top_offset: Scalar

Offset of the top edge relative to the bottom; may be negative.

Trait Implementations

impl Clone for SectionProfile

fn clone(&self) -> SectionProfile

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SectionProfile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SectionProfile

fn eq(&self, other: &SectionProfile) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
