- class concreteproperties.stress_strain_profile.EurocodeParabolicUltimate(compressive_strength: float, compressive_strain: float, ultimate_strain: float, n: float, n_points: int = 10)[source]#
Bases:
ConcreteUltimateProfile
Class for an ultimate parabolic stress-strain relationship to EC2.
- Parameters:
compressive_strength (float) – Concrete compressive strength
compressive_strain (float) – Strain at which the concrete stress equals the compressive strength
ultimate_strain (float) – Concrete strain at failure
n (float) – Parabolic curve exponent
n_points (int) – Number of points to discretise the parabolic segment of the curve
Methods

Returns the ultimate strain, or largest compressive strain.
Returns the largest tensile strain.
Returns an ordered list of unique strains.
Returns the yield strength of the stress-strain profile.
Plots the stress-strain profile.
Prints the stress-strain profile properties to the terminal.
