sectionproperties.pre.library.bridge_sections.super_t_girder_section(girder_type: int, girder_subtype: int = 2, w: float = 2100, t_w: float | None = None, t_f: float = 75, material: Material = Material(name='default', elastic_modulus=1, poissons_ratio=0, yield_strength=1, density=1, color='w')) → Geometry

Constructs a super T girder section to AS5100.5.

Parameters:

• girder_type (int) – Type of super T (1 to 5)

• girder_subtype (int) – Era super T (1: pre-2001, 2: contemporary)

• w (float) – Overall width of top flange

• t_w (float | None) – Web thickness of the Super-T section, if None defaults to those of AS5100.5 Tb D3(B)

• t_f (float) – Thickness of top flange (VIC = 75 mm; NSW = 90 mm)

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

Raises:

ValueError – girder_type or girder_subtype are invalid

Returns:

Super T girder section geometry

Return type:

Geometry

Example

The following example creates a T5 super T section with a 180 mm overlay slab:

from sectionproperties.pre.library import super_t_girder_section
from sectionproperties.pre.library import rectangular_section

super_t = super_t_girder_section(girder_type=5, w=2100)
slab = rectangular_section(d=180, b=2100).shift_section(
    x_offset=-1050, y_offset=75
)
(super_t + slab).plot_geometry()
