Foreword This document has been prepared by Working Committee NA 005-01-07 Bemessung und Konstruktion (SpA CEN/TC 250/SC 2) of the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committee). This document is the National Annex to DIN E
6、N 1992-3 Eurocode 2: Design of concrete structures Part 3: Liquid retaining and containment structures. European Standard EN 1992-3 allows national safety parameters, referred to as Nationally Determined Parameters (NDPs), to be specified for a number of points. The NDPs cover alternative verificati
7、on 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 inc
8、ludes non-contradictory complementary information (NCI) for the application of DIN EN 1992-3:2011-01. This National Annex is an integral part of DIN EN 1992-3:2011-01. Amendments This document differs from DIN 1045-1:2008-08 as follows: a) a number of provisions from DIN 1045:2008-08 regarding concr

NOTE 1 The design and minimum thickness of wall members shall be selected so that the members have the required minimum concrete cover and number of reinforcement layers, t
26、hat the joints can be properly sealed and inserts cast in a workmanlike manner, and the loadbearing and sealing function of the concrete is ensured in addition to all other relevant requirements being satisfied. NOTE 2 For higher grades of concrete (i.e. where (w/c)eq 0,45), adequate water resistanc
27、e will be ensured even if smaller member thicknesses are used, with the member thickness t1(= t2), however being not lower than 200 mm for in situ concrete walls and 160 mm for precast members.
