Materials, coefficients, notation

The following notation for material parameters is used:

f'c - characteristic copressive cylinder strength of concrete at 28 days
Ec - mean value of the modulus of elasticity of concrete at 28 days
ρ - density of concrete , in kilograms per cubic metre (kg/m3)
f'cf - characteristic flexural tensile strength of concrete
f'ct - characteristic principal tensile strength of concrete
fsy - yield strength of reinforcing steel

The characteristic compressive strength of concrete is the basic input parameter given by the class of concrete.

The most common notation for geometrical parameters:

b - cross-section width
D - cross-section depth
d - effective depth of cross-section
z - lever arm (arm of internal forces)

All computations are carried out according to the theory of limit states.
