BarPlacementUtil

Implementation of the bar placement utilities

Functions:

    placement_diameter: float,
    local_angles: RotationAngles,
) -> float

For the placement of longitudinal bars, located on one of the legs of a transverse bar (e.g. a stirrup), this function calculates the X-component between the edge of the concrete cross-section and the start point of the placement of the longitudinal bars

│    │           │    │
│    │           │    │
│    │ o   o   o │ <- longitudinal bars
│    ╰───────────╯ <- transverse bar (e.g. stirrup)
│                     │
└─────────────────────┘ outline
<-----> calculated distance

Parameters:

  • shape (BendingShape) –

    Bending shape of the transverse bar

  • side_number (int) –

    Number of the leg, on which the longitudinal bars are located (starting from 1)

  • bending_roller (float) –

    Bending roller if the transverse bar

  • base_line (Line2D | Line3D) –

    The outline of the concrete cross section

  • placement_diameter (float) –

    Bar diameter of the longitudinal bars

  • local_angles (RotationAngles) –

    Model angles to get the local x/y coordinate system for the calculation

Returns:

  • float –

    Calculated distance to the placement start

Parameters:

  • shape (BendingShape) –

    Bending shape of the transverse bar

  • global_point (bool, default: False ) –

    If set to True, the result will be a point in global coordinates. Otherwise, the point in local coordinate system will be returned.

Returns:

  • Point3D –

    Local point of the longitudinal bar placement
