Reinforcement steel materials¶

Reinforcement steel factory¶

structuralcodes.materials.reinforcement.create_reinforcement(fyk: float, Es: float, ftk: float, epsuk: float, gamma_s: float | None = None, name: str | None = None, density: float = 7850, design_code: str | None = None) → Reinforcement | None[source]¶

A factory function to create the correct type of reinforcement based on the desired design code.

Parameters:

fyk (float) – Characteristic yield strength in MPa.
Es (float) – The Young’s modulus in MPa.
ftk (float) – Characteristic ultimate strength in MPa.
epsuk (float) – The characteristik strain at the ultimate stress level.

Keyword Arguments:

gamma_s (Optional(float)) – The partial factor for reinforcement.
density (float) – Density of the material in kg/m3 (default: 7850)
design_code (str) – Optional string (default: None) indicating the desired standard. If None (default) the globally used design standard will be adopted. Otherwise the design standard specified will be used for the instance of the material.

Raises:

ValueError – If the design code is not valid or does not cover reinforcement as a material.
