28、uss Bauwesen (Building and Civil Engineering Standards Committee). This document is the National Annex to DIN EN 1996-1-1:2010-12, Eurocode 6: Design of masonry structures Part 1-1: General rules for reinforced and unreinforced masonry structures. European Standard EN 1996-1-1:2005 allows national s

29、afety 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 designated classification systems. The relevant parts of the text ar

30、e 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 DIN EN 1996-1-1:2010-12 National paragraphs are preceded by the letter

31、s “NA” and the paragraph number in brackets. Reference is made in National Annex to European Technical Approvals and German national technical approvals. These are referred to hereinafter as “approvals”. This National Annex is an integral part of DIN EN 1996-1-1:2010-12. Amendments This document dif

32、fers from DIN 1053-1:1996-11, DIN 1053-3:1990-02 and DIN 1053-100:2007-09 as follows: a) The simplified and detailed calculation methods are dealt with in separate parts of the standard; b) the standard has been restructured; c) the semi-probabilistic safety concept has been introduced; d) reference

33、 is made to characteristic strength values; e) the calculation method has been revised, both technically and editorially; f) the figures have been editorially revised; g) masonry made of high-precision masonry elements has been included; h) nationally determined parameters (NDP) have been introduced

34、 in accordance with EN 1996-1-1; i) additional non-contradictory complementary information (NCl) has been included. The following corrections have been made to DIN EN 1996-1-1/NA:2012-01: a) the full text of the NDP re 3.6.2 and the NDP and NCI re 3.6.3 is now included; b) a reference to a standard

35、in the NCI re 3.1.1, (NA.5 ) has been corrected; c) a key has been added to Figure NA.9 und references to tables in Annex NA.M have been corrected.
