SteelStrand¶

class concreteproperties.material.SteelStrand(name: str, density: float, stress_strain_profile: StrandProfile, colour: str, prestress_stress: float = 0)[source]¶

Bases: Steel

Class for a steel strand material.

This steel strand material is treated as a lumped circular mass with a constant strain.

Note

A StrandProfile must be used if using a SteelStrand object.

Note

The strand is assumed to be bonded to the concrete.

Parameters:

name (str) – Steel strand material name
density (float) – Steel strand density (mass per unit volume)
stress_strain_profile (StrandProfile) – Steel strand stress-strain profile
colour (str) – Colour of the material for rendering, see https://matplotlib.org/stable/gallery/color/named_colors.html for a list of named colours
prestress_stress (float) – Prestressing stress applied to the strand. Defaults to 0.

Methods

`get_prestress_strain`	Returns the prestress strain.
`get_prestress_stress`	Returns the prestress stress.
