This document is the National Annex to DIN EN 1993-4-2:2010-12, Eurocode 3: Design of steel struct
7、ures Part 4-2: Tanks. European Standard EN 1993-4-2 allows national safety parameters, referred to as Nationally Determined 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
8、 designated classification systems. The relevant parts of the text are identified in the European Standard by references to the possibility of national choice and are listed in Clause NA 2.1. This National Annex also includes non-contradictory complementary information (NCI) for the application of D
