concreteproperties.material.SteelStrand#

class SteelStrand(name, density, stress_strain_profile, colour, prestress_stress=0)[source]#

Class for a steel strand material, 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
prestress_stress (float, default: 0) – Prestressing stress applied to the strand

Methods

`get_prestress_strain`	Given the strand cross-sectional area, returns the prestress strain.
`get_prestress_stress`	Returns the prestress stress.

Attributes

get_prestress_stress()[source]#

Returns the prestress stress.

get_prestress_strain(area)[source]#

Given the strand cross-sectional area, returns the prestress strain.
