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[np.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[np.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]) – List of strand geometry objects present in the stress analysis

• strand_stresses (list[float]) – List of strand stresses for each strand

• strand_strains (list[float]) – List of strand strains for each strand

• strand_forces (list[tuple[float, float, float]]) – List of net forces for each strand geometry and its lever arm (force, d_x, d_y)
