Hinweise für den Ansatz der Betonzugfestigkeit beim Nachweis der Mindestbewehrung für frühen Zwang gemäß Eurocode 2-2 (DIN EN 1992-2/NA)

Guideline for the assumption of the effective concrete tensile strength within the minimum reinforcement check due to early cracking according to Eurocode 2-2 (DIN EN 1992-2/NA)

In December 2015, the A1-amendment [1] for the German National Annex [2] of DIN EN 1992-1-1 was published. The amendment affects among others the assumption of the effective concrete tensile strength within the minimum reinforcement check due to early cracking. The following contribution elucidates the background, why a respective A1-amendment for DIN EN 1992-2/NA has not been provided. Furthermore, the main differences between building- and bridge constructions are outlined in order to constitute the different approach.
