This document is the National Annex to DIN EN 1994-1-1:2010-12, Eurocode 4 Design of composite steel and concrete structures Part 1-1: General rules and rules for buildings. European Standard EN 1994-1-1:2004 allows national safety parameters, referred to as Nationally Dete

10、rmined Parameters (NDPs), to be specified for a number of points. The NDPs cover alternative verification methods, the provision of individual values and the selection of classes from designated classification systems. The relevant parts of the text are identified in the European Standard by referen
