Concrete

class compas_model.materials.Concrete(fck, fck_cube=None, fcm=None, fctm=None, Ecm=None, density=2400, poisson=0.2, name=None)

Bases: Material

Class representing a generic concrete material.

Parameters:

fckfloat

Characteristic cylinder compressive strength in [MPa].

fck_cubefloat, optional

Characteristic cube compressive strength in [MPa]. If not provided, fck_cube = 1.25 * fck is used.

fctmfloat, optional

Mean tensile strength in [MPa]. If not provided, fctm = 0.1 * fck is used.

Ecmfloat, optional

Modulus of elasticity in [GPa].

densityfloat, optional

Density of the material in [kg/m3]. If not provided, 2400 kg/m3 is used.

poissonfloat, optional

Poisson’s ratio. If not provided, poisson = 0.2 is used.

namestr, optional

Name of the material.

Attributes:

fckfloat

Characteristic cylinder compressive strength in [MPa].

fck_cubefloat

Characteristic cube compressive strength in [MPa].

fcmfloat

Mean compressive strength as fcm = fck + 8 Mpa.

fctmfloat

Mean tensile strength in [MPa].

Ecmfloat

Modulus of elasticity in [MPa].
