LinearBarPlacementBuilder

Implementation of the linear placement bar placement builder

StartEndPlacementRule

Canonical path: StdReinfShapeBuilder.LinearBarPlacementBuilder.StartEndPlacementRule

Bases: IntEnum

Rules for linear rebar placements, determining how rebars are distributed when the placement length is not an exact multiple of the spacing

AdaptDistance class-attribute instance-attribute 

AdaptDistance = 4

Spacing is adapted to match the placement length

AdditionalCover class-attribute instance-attribute 

AdditionalCover = 1

Spacing is preserved, concrete cover is increased at both ends

AdditionalCoverLeft class-attribute instance-attribute 

AdditionalCoverLeft = 2

Spacing is preserved, concrete cover at start is increased

AdditionalCoverRight class-attribute instance-attribute 

AdditionalCoverRight = 3

Spacing is preserved, concrete cover at end is increased

calculate_length_of_regions 

calculate_length_of_regions(
    value_list: list[tuple[float, float, float]],
    from_point: Point3D,
    to_point: Point3D,
    concrete_cover_left: float,
    concrete_cover_right: float,
) -> list[tuple[Point3D, Point3D]]

Create list with the start and end points of individual linear placements (called regions), that compose one, greater linear placement. The points are calculated based on region's length, bar spacing to be applied in the region and the rebar diameter, that should be placed in the region. This is a helper function to be used in combination with the create_linear_bar_placement_from_to_by_dist function to create e.g., stirrups inside beams, where the spacing varies along the beam's axis.

Parameters:

  • value_list (list[tuple[float, float, float]]) –

    list with individual placement regions represented by tuples (region length, bar spacing, bar diameter). IMPORTANT: At least one region must have a zero length. Its length will be calculated by the function, so that the total sum of all region lengths equals the distance between start and end point.

  • from_point (Point3D) –

    Start point of the total parent

  • to_point (Point3D) –

    End point of the total

  • concrete_cover_left (float) –

    Concrete cover at the start point

  • concrete_cover_right (float) –

    Concrete cover at the end point

Returns:

  • list[tuple[Point3D, Point3D]] –

    Bar placement points as list of tuples (start point, end point)

check_placement_length_by_distance 

check_placement_length_by_distance(length: float, distance: float) -> float

Adjusts the length of the placement so that it is a multiple of the rebar spacing

Parameters:

  • length (float) –

    length of the placement

  • distance (float) –

    rebar spacing

Returns:

  • float –

    Adjusted length of the placement
