Berücksichtigung der Längsbewehrung beim Durchstanznachweis nach Eurocode 2 (DIN EN 1992-1-1/NA)

Consideration of flexural reinforcement in punching shear provisions according to Eurocode 2 (DIN EN 1992-1-1/NA)

With introduction of Eurocode 2 in Germany in 2012, the punching shear design provisions of flat slabs and column bases were revised compared to DIN 1045-1. Particularly the consideration of flexural reinforcement caused some irritations for practical engineers. In this context, this paper presents recent recommendations of DIN technical committee "NABau" (DIN: German institute for standardization) for the distribution of minimum flexural reinforcement for wall corners and wall edges as well as for the width and anchorage of flexural reinforcement for the calculation of the flexural reinforcement ratio in flat slabs and column bases.
