Fatigue check

In previous releases when assessing concrete for fatigue, the stress in the concrete was calculated based on the parabolic-rectangular stress-strain diagram.

According to Eurocode the tensile strength of concrete shall be ignored and a linear stress-strain relationship for concrete under compression shall be used. Now for fatigue verification, we use the same stress-strain diagrams as in SLS checks, i.e., an unlimited linear stress-strain diagram.
