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)
strand_geometries (List[CPGeom], default: <factory>) – List of strand geometry objects present in the stress analysis
strand_stresses (List[float], default: <factory>) – List of strand stresses for each strand
strand_strains (List[float], default: <factory>) – List of strand strains for each strand
strand_forces (List[Tuple[float, float, float]], default: <factory>) – List of net forces for each strand geometry and its lever arm (force, d_x, d_y)

plot_stress(title='Stress', conc_cmap='RdGy', reinf_cmap='bwr', **kwargs)[source]#

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
