class compas_fea2.model.Concrete

Bases: _Material

Elastic and plastic-cracking Eurocode based concrete material

Parameters:

fckfloat

Characteristic (5%) 28 day cylinder strength [MPa].

vfloat

Poisson’s ratio v [-].

frlist, optional

Failure ratios.

densityfloat, optional

Density of the concrete material [kg/m^3].

namestr, optional

Name of the material.

Attributes:

Efloat

Young’s modulus E.

vfloat

Poisson’s ratio v.

Gfloat

Shear modulus G.

fckfloat

Characteristic (5%) 28 day cylinder strength.

frlist

Failure ratios.

tensiondict

Parameters for modelling the tension side of the stress-strain curve.

compressiondict

Parameters for modelling the compression side of the stress-strain curve.

Notes

The concrete model is based on Eurocode 2 up to fck=90 MPa.
