class StressResult(concrete_section, concrete_analysis_sections, concrete_stresses, concrete_forces, meshed_reinforcement_sections, meshed_reinforcement_stresses, meshed_reinforcement_forces, lumped_reinforcement_geometries, lumped_reinforcement_stresses, lumped_reinforcement_strains, lumped_reinforcement_forces)

Bases: object

Class for storing stress results.

The lever arm is computed to the elastic centroid.

Parameters

• concrete_analysis_sections (List[AnalysisSection]) – List of concrete analysis section objects present in the stress analysis, which can be visualised by calling the plot_mesh() or plot_shape()

• concrete_stresses (List[ndarray]) – List of concrete stresses at the nodes of each concrete analysis section

• concrete_forces (List[Tuple[float, float, float]]) – List of net forces for each concrete analysis section and its lever arm (force, d_x, d_y)

• meshed_reinforcement_sections (List[AnalysisSection]) – List of meshed reinforcement section objects present in the stress analysis

• meshed_reinforcement_stresses (List[ndarray]) – List of meshed reinforcement stresses at the nodes of each meshed reinforcement analysis section

• meshed_reinforcement_forces (List[Tuple[float, float, float]]) – List of net forces for each meshed reinforcement analysis section and its lever arm (force, d_x, d_y)

• lumped_reinforcement_geometries (List[CPGeom]) – List of lumped reinforcement geometry objects present in the stress analysis

• lumped_reinforcement_stresses (List[float]) – List of lumped reinforcement stresses for each lumped geometry

• lumped_reinforcement_strains (List[float]) – List of lumped reinforcement strains for each lumped geometry

• lumped_reinforcement_forces (List[Tuple[float, float, float]]) – List of net forces for each lumped reinforcement geometry and its lever arm (force, d_x, d_y)

plot_stress(title='Stress', conc_cmap='RdGy', reinf_cmap='bwr', **kwargs)

Plots concrete and steel stresses on a concrete section.

Parameters

• title (str, default: 'Stress') – Plot title

• conc_cmap (str, default: 'RdGy') – Colour map for the concrete stress

• reinf_cmap (str, default: 'bwr') – Colour map for the reinforcement stress

• kwargs – Passed to plotting_context()

Returns

Axes – Matplotlib axes object

sum_forces()

Returns the sum of the internal forces.

Returns

float – Sum of internal forces

sum_moments()

Returns the sum of the internal moments.

Returns

Tuple[float, float, float] – Sum of internal moments about each axis and resultant moment (m_x, m_y, m)
