m_n_kappa.RebarLayer

class m_n_kappa.RebarLayer(rebar_diameter, centroid_z, rebar_number=None, width=None, left_edge=None, right_edge=None, rebar_horizontal_distance=None)

Bases: ComposedGeometry

rebar-layer composed of several reinforcement-bars of Circle

New in version 0.1.0.

Parameters:

• rebar_diameter (float) – diameter of rebars in the layer

• centroid_z (float) – position of the centroid in vertical direction

• rebar_number (int = None) – number of rebars within the layer (Alternative to argument width)

• width (float = None) – width of the rebar-layer \(b\) (together with rebar_horizontal_distance alternative to argument rebar_number). In case rebar_number is defined, the argument width as well as rebar_horizontal_distance value is ignored.

• rebar_horizontal_distance (float) – distance between the rebars in horizontal direction \(s_\mathrm{y}\) (Default: None). See description in argument width.

• left_edge (float) – horizontal position of the centroid of the left-most circle \(y_\mathrm{left}\) (Default: None).

• right_edge (float) – horizontal position of the centroid of the right-most circle \(y_\mathrm{right}\) (Default: None)

• rebar_horizontal_distance – horizontal-distance between the rebar-centroids \(s_\mathrm{y}\) (Default: None)

Example

The following example creates 10 circles with diameter 12 and a vertical position of 10

>>> from m_n_kappa import RebarLayer
>>> rebar_layer = RebarLayer(rebar_diameter=12.0, centroid_z=10.0, rebar_number=10, rebar_horizontal_distance=100)

Adding a material to rebar_layer creates a cross-section.

>>> from m_n_kappa import Reinforcement
>>> rebar_steel = Reinforcement(f_s=500, f_su=550, failure_strain=0.25)
>>> rebars = rebar_layer + rebar_steel
>>> rebars
