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 reinforcement) after a cracked analysis.
`print_results`	Prints the cracked concrete section properties to the terminal.
`reset_results`	Resets the analysis results.

Return type: None

calculate_transformed_properties(elastic_modulus)[source]#

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

Parameters: elastic_modulus (float) – Reference elastic modulus

plot_cracked_geometries(title='Cracked Geometries', **kwargs)[source]#

Plots the geometries that remain (are in compression or are reinforcement) after a cracked analysis.

Parameters

title (str, default: 'Cracked Geometries') – Plot title
kwargs – Passed to plot_geometry()

Returns

Axes – Matplotlib axes object
