)

Bases: ReinforcedCrossSection

Representation of a reinforced circular concrete cross-section like a column.

Parameters:

  • diameter (MM) –

    The diameter of the circular cross-section [mm].

  • concrete_material (ConcreteMaterial) –

    Material properties of the concrete.

  • cover (MM, default: DEFAULT_COVER ) –

Add longitudinal reinforcement to the cross-section based on the quantity configuration of rebars.

Parameters:

  • n (int) –

    Amount of longitudinal bars.

  • diameter (MM) –

    Diameter of the rebars [mm].

  • material (ReinforcementSteelMaterial) –

    Representation of the properties of reinforcement steel suitable for use with NEN-EN 1992-1-1.

  • cover (MM | None, default: None ) –

    Cover of the rebars [mm]. If not provided, the default cover is used.

  • start_angle (DEG, default: 90.0 ) –

    Starting position of the first rebar. Default is 90 degrees which is the top of the circle. 0 degrees is the right side of the circle. 180 degrees is the right side of the circle.

) -> StirrupConfiguration

Adds a stirrup configuration along the perimeter of the cross-section taking the covers into account. The created configuration goes around the longitudinal rebars (if any).

Use .add_stirrup_configuration() to add a stirrup configuration of any shape, size, and position (as long as it is inside the cross-section).

Parameters:

  • diameter (MM) –

    Diameter of the stirrups [mm].

  • distance (MM) –

    Longitudinal distance between stirrups [mm].

  • material (ReinforcementSteelMaterial) –

    Representation of the properties of reinforcement steel suitable for use with NEN-EN 1992-1-1

  • shear_check (bool, default: True ) –

    Take stirrup into account in shear check

  • torsion_check (bool, default: True ) –

    Take stirrup into account in torsion check

  • mandrel_diameter_factor (DIMENSIONLESS | None, default: None ) –

    Inner diameter of mandrel as multiple of stirrup diameter [-] (default: 4⌀ for ⌀<=16mm and 5⌀ for ⌀>16mm) Tabel 8.1Na NEN-EN 1992-1-1 Dutch National Annex.

  • anchorage_length (MM, default: 0.0 ) –

    Anchorage length [mm]

  • relative_start_position (RATIO, default: 0.0 ) –

    Relative position of the start of the stirrup configuration inside the cross-section (longitudinal direction). Value between 0 and 1. Default is 0 (start).

  • relative_end_position (RATIO, default: 1.0 ) –

    Relative position of the end of the stirrup configuration inside the cross-section (longitudinal direction). Value between 0 and 1. Default is 1 (end).

Returns:

  • StirrupConfiguration –

    Newly created stirrup configuration inside the cross-section.
