Version Information Welcome to the Theoretical Background for National Annexes to EN 1999. This document provides background information regarding the application of NDP items according to different countries. Version info Document Title Theoretical Background National Annexes to EN 1999 Release 17.0 Revision 04/2017 1
Introduction In this Theoretical background in depth information is given regarding the application of National Annexes to EN 1999 for different countries. More specifically this concerns the following codes: Eurocode 9 Design of aluminum structures Part 1-1: General structural rules EN 1999-1-1:2007 Addendum EN 1999-1-1:2007/A1:2009 The first chapter gives an overview of all NDP articles given in EN 1999 and specifies which of those articles are supported by SCIA Engineer. The subsequent chapters provide details on the specific implementation of the supported articles for different countries. 2
National Choice in EN 1999 This chapter specifies the articles of EN 1999 in which a national choice is allowed. In addition for each article information is given if the article is supported within SCIA Engineer. EN 1999-1-1 1.1.2(1) The NA may define minimal material thickness 2.1.2(3) The NA may specify reliability level 2.3.1(1) The NA may define additional actions 3.2.1(1) The NA may define additional alloys 3.2.2(1) The NA may give additional rules 3.2.2(2) The NA may give additional rules 3.2.3.1(1) The NA may give additional rules 3.3.2.1(3) The NA may give additional provisions 3.3.2.2(1) The NA may give additional rules 5.2.1(3) The NA may give a different criterion 5.3.2(3) The NA may define the bow imperfections NA data supported in SCIA Engineer 5.3.4(3) The NA may define the imperfection k NA data supported in SCIA Engineer 6.1.3(1) The NA may define the safety factors NA data supported in SCIA Engineer 3
6.2.1(5) The NA may define the constant C NA data supported in SCIA Engineer 7.1(4) The NA may give further guidance 7.2.1(1) The NA may define deflection limits 7.2.2(1) The NA may define deflection limits 7.2.3(1) The NA may define vibration limits 8.1.1(2) The NA may define the safety factors 8.9(3) The NA may give additional provisions A.2(1) [Addendum] The NA may give additional provisions C.3.4.1(2) The NA may define the safety factors C.3.4.1(3) The NA may define the safety factors C.3.4.1(4) The NA may define the safety factors K.1(1) The NA may give additional provisions K.3(1) The NA may specify the method 4
National Annexes This chapter provides details on the specific implementation of the supported articles for different countries. Only those items for which a country differs from the default EN are elaborated. For more information reference is made to the EN code and the respective National Annex documents. EN 1999-1-1 Austria Belgium According to Belgian National Annex NBN EN 1999-1-1 ANB: 2011. Cyprus According to Cypriot National Annex CYS EN 1999-1-1:2007/NA: 2010-06. 5
Czech Republic According to Czech National Annex CSN EN 1999-1-1/NA ed.a:2011-11. Note: The buckling class from the material is used, independent of the class of the section. Denmark According to Danish National Annex DS/EN 1999-1-1 DK NA:2013. Note: The buckling class from the material is used, independent of the class of the section. 6.1.3(1) The safety factors are set as follows for ULS set B: Gamma M1 = 1,2 x Gamma 0 x Gamma 3 Gamma M2 = 1,35 x Gamma 0 x Gamma 3 Gamma 0 = 1,00 Gamma 3 depends on the Inspection level. Inspection level = Normal (= default setting) Gamma 3 = 1,00 Inspection level = Strict Gamma 3 = 0,95 The safety factors are set as follows for Accidental combinations (psi1 or psi2) or Seismic combinations: Gamma M1 = 1,0 Gamma M2 = 1,0 6
