fconcrete.StructuralConcrete.Concrete module¶

class fconcrete.StructuralConcrete.Concrete.Concrete(fck, aggressiveness, aggregate='granite')[source]¶

Define the Concrete to be used and all its properties.

Attributes:

fck : number: Define the characteristic resistance of the concrete in kN/cmˆ2.
E_ci : number: Modulus of elasticity or initial tangent deformation module of concrete, always referring to the cordal module in kN/cmˆ2.
E_cs : number: Secant deformation module of concrete in kN/cmˆ2.
fctm : number: Average concrete tensile strength in kN/cmˆ2.
fctk_inf : number: Minimum value of direct tensile strength in kN/cmˆ2.
fctk_sup : number: Maximum value of direct tensile strength in kN/cmˆ2.
fcd : number: Minimum value of design direct tensile strength in kN/cmˆ2.
c : number: Concrete covering in cm.
wk : number: Characteristic crack opening in the concrete surface in cm.
