7、DIN EN 1991-1-6:2010-12, Actions on structures Part 1-6: General actions Actions during execution. European Standard EN 1991-1-6 allows national safety parameters, referred to as Nationally Determined Parameters (NDPs), to be specified for a number of points. The NDPs cover alternative verification

8、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 references to the possibility of national choice and are listed in Clause NA 2.1. This National Annex also includ
