Vergleich der nationalen Anhänge der EN 1992-1-1 zum Thema Querkraft und Durchstanzen

Shear and Punching Shear verifications in comparison to the national annexes of the Eurocode 2

In order to get the Eurocodes accepted, it was necessary to allow national choices with regard to parameters where no agreement between the countries involved could be reached. For the part EN 1992-1-1 "Design of concrete structures - Part I: General rules and rules for buildings" altogether 121 parameters have been defined which are subject to national choices. A comparison of the national choices can show where in future easily agreement can be reached. On the other hand parameters can be identified for which significant disagreement exist, which invites to further discussions and even research. In this paper, as an experiment, the nationally defined parameters of 18 countries are compared for the chapters on shear and punching, which subjects are now, for several reasons, again in the centre of interest.
