Distribution Coefficient

Distribution coefficient for the deformation analysis according to EN 1992-1-1

ζ = 1 - β \cdot {(\frac{f_{ctm}}{σ_{\max}})}^{2}

β	Parameters for the influence of load duration or load repetitions
f_ctm	mean tensile strength of concrete
σ_max	Concrete tension stress under the assumption of linear-elastic material behavior
