Bases: object

Class for storing cracked concrete section properties.

All properties with an e_ preceding the property are multiplied by the elastic modulus. In order to obtain transformed properties, call the calculate_transformed_properties() method.

Parameters

theta (float) – Angle (in radians) the neutral axis makes with the horizontal axis (\(-\pi \leq \theta \leq \pi\))

Methods

calculate_transformed_properties	Calculates and stores transformed cracked properties using a reference elastic modulus.
plot_cracked_geometries	Plots the geometries that remain (are in compression or are steel) after a cracked analysis.
print_results	Prints the cracked concrete section properties to the terminal.

calculate_transformed_properties(elastic_modulus: float)

Calculates and stores transformed cracked properties using a reference elastic modulus.

Parameters

elastic_modulus (float) – Reference elastic modulus

plot_cracked_geometries(title: Optional[str] = 'Cracked Geometries', **kwargs) → matplotlib.axes.Axes

• kwargs – Passed to plot_geometry()

Returns

Matplotlib axes object

Return type

matplotlib.axes.Axes

print_results(fmt: Optional[str] = '8.6e')

Prints the cracked concrete section properties to the terminal.

Parameters

fmt (Optional[str]) – Number format
