concreteproperties.results.StressResult

class StressResult(concrete_section: ConcreteSection, concrete_analysis_sections: List[AnalysisSection], concrete_stresses: List[np.ndarray], concrete_forces: List[Tuple[float]], steel_geometries: List[Geometry], steel_stresses: List[float], steel_strains: List[float], steel_forces: List[Tuple[float]])

Bases: object

Class for storing stress results.

For uncracked and cracked analyses, the lever arm is the distance to the elastic centroid.

For service stress analyses, the lever arm is the distance to the computed centroid.

For ultimate stress analyses, the lever arm is the distance to the plastic centroid.

Variables

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

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

• steel_geometries (List[sectionproperties.pre.geometry.Geometry]) – List of steel geometry objects present in the stress analysis

• steel_stresses (List[float]) – List of steel stresses for each steel geometry

• steel_strains (List[float]) – List of steel strains for each steel geometry

• steel_forces (List[Tuple[float]]) – List of net forces for each steel geometry and its lever arm to the neutral axis (force, d_x, d_y)

Methods

plot_stress	Plots concrete and steel stresses on a concrete section.
