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

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.
