MomentInteractionResults

class concreteproperties.results.MomentInteractionResults(results: list[~concreteproperties.results.UltimateBendingResults] = <factory>)

Bases: object

Class for storing moment interaction results.

Parameters:

results (list[UltimateBendingResults]) – List of ultimate bending result objects

Methods

get_results_lists	Returns a list of axial forces and moments.
plot_diagram	Plots a moment interaction diagram.
plot_multiple_diagrams	Plots multiple moment interaction diagrams.
point_in_diagram	Determines whether or not the design point lies within the diagram.
sort_results	Sorts the results by decreasing axial force.

Attributes

results

sort_results() → None

Sorts the results by decreasing axial force.

get_results_lists(moment: str) → tuple[list[float], list[float]]

Returns a list of axial forces and moments.

Parameters:

moment (str) – Which moment to plot, acceptable values are "m_x", "m_y" or "m_xy"

Raises:

ValueError – If the moment string is not valid

Returns:

List of axial forces and moments (n, m)

Return type:

tuple[list[float], list[float]]

plot_diagram(n_scale: float = 0.001, m_scale: float = 1e-06, moment: str = 'm_x', fmt: str = 'o-', labels: bool = False, label_offset: bool = False, **kwargs) → matplotlib.axes.Axes

Plots a moment interaction diagram.

Parameters:

• n_scale (float) – Scaling factor to apply to axial force

• m_scale (float) – Scaling factor to apply to the bending moment

• moment (str) – Which moment to plot, acceptable values are "m_x", "m_y" or "m_xy"

• fmt (str) – Plot format string

• labels (bool) – If set to True, also plots labels on the diagram

• label_offset (bool) – If set to True, attempts to offset the label from the diagram

• kwargs – Passed to plotting_context()

Returns:

Matplotlib axes object

Return type:

matplotlib.axes.Axes

Plots multiple moment interaction diagrams.

Parameters:

• moment_interaction_results (list[MomentInteractionResults]) – List of moment interaction results objects

• labels (list[str]) – List of labels for each moment interaction diagram

• n_scale (float) – Scaling factor to apply to axial force

• m_scale (float) – Scaling factor to apply to bending moment

• moment (str) – Which moment to plot, acceptable values are "m_x", "m_y" or "m_xy"

• fmt (str) – Plot format string

• kwargs – Passed to plotting_context()

Returns:

Matplotlib axes object

Return type:

matplotlib.axes.Axes

point_in_diagram(n: float, m: float, moment: str = 'm_x') → bool

Determines whether or not the design point lies within the diagram.

Parameters:

• n (float) – Axial force

• m (float) – Bending moment

• moment (str) – Which moment to analyse, acceptable values are "m_x", "m_y" or "m_xy"

Returns:

True, if combination of axial force and moment is within the diagram

Return type:

bool
