This document is the National Annex to DIN EN
14、1993-1-8:2010-12, Eurocode 3: Design of steel structures Part 1-8: Design of joints. European Standard EN 1993-1-8 allows national safety parameters, referred to as Nationally Determined Parameters (NDPs), to be specified for a number of points. The NDPs cover alternative verification methods, the p
15、rovision 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 includes non-contrad
16、ictory complementary information (NCI) for the application of DIN EN 1993-1-8:2010-12. This National Annex is an integral part of DIN EN 1993-1-8:2010-12. DIN EN 1993-1-8:2010-12 and this National Annex, DIN EN 1993-1-8/NA:2010-12, partially supersede DIN 18800-1:2008-11, DIN 18801:1993-09, DIN 1880

26、 1.2.6 (Reference standard group 6: Rivets) Note Pending the publication of the relevant European Standard, rivet dimensions shall conform to DIN 124 and DIN 302, whilst rivet materials are to be specified on a case-by-case basis. NDP re 2.2(2) Note The recommended values shall apply. In addition, t
27、he following shall apply: M2,S420 = 1,25, taking was 0,88 instead of 1,0 as in DIN EN 1993-1-8:2010-12, Table 4.1 M2,S460 = 1,25, taking was 0,85 instead of 1,0 as in DIN EN 1993-1-8:2010-12, Table 4.1. The use of injection bolts requires a bauaufsichtlicher Verwendbarkeitsnachweis. NOTE A bauaufsic
28、htlicher Verwendbarkeitsnachweis can take the form of a: European Technical Approval (ETA), German national technical approval (agrment), or permission on a case-by-case basis. NCI re 3.1.1 Galvanized bolts Only complete bolt assemblies with elements (bolts, nuts and washers) originating from one an
29、d the same manufacturer shall be used. Hot dip galvanized bolts of property classes 8.8 and 10.9 and the associated nuts and washers shall only be used if they have been galvanized either at the manufacturers works or by a third party under the responsibility of the manufacturer. Other types of meta
30、llic protective coating may be used provided that their compatibility with steel is ensured, hydrogen embrittlement is precluded and proof of adequate tightening characteristics is provided. Electrogalvanized bolts of property classes 8.8 and 10.9 shall not be used. DIN EN 1993-1-8/NA:2010-12 6 NOTE
31、 1 Electrogalvanizing is another example of a metallic protective coating. It may only be used as the sole means of corrosion protection where bolts are intended for use in dry rooms (cf. corrosion class C1 as in DIN EN ISO 12944-2). NOTE 2 See DIN 267-9 for further information regarding the prevent
32、ion of hydrogen embrittlement. NDP re 3.1.1(3) Note The use of bolts of property classes 4.8, 5.8 and 6.8 is not permitted in structural steelwork. NDP re 3.4.2(1) Note For tightening bolted connections of categories B and C using a preloading force Fp,C= 0,7 fubAsand of category E using the full pr
33、eloading force, the combined method according to DIN EN 1090-2 is to be used. For preloading as a quality assurance measure and for partially preloaded connections of category E, a preloading force up to Fp,C* = 0,7 fybAsmay be used, which may be applied using one of the methods described in Annex A
34、. For securing an assembly against working loose, a preloading force equal to 50 % of Fp,C* is normally deemed sufficient. NCI re 3.5 Blind bolted connections The following specifications apply to assemblies of sizes up to M100. For bolted connections which are not a bolt-nut assembly (e.g. connecti
35、ons using threaded rods and threaded blind holes), the engagement depth may be considered to be adequate if the ratio of engagement depth to external thread diameter satisfies at least the following condition: = (600/fu,k) (0,3+0,4fu,b,k/500), and if fu,k fu,b,k. In the above, fu,k is the characteri
36、stic tensile strength of the component with an internal thread, in N/mm; fu,b,k is the characteristic tensile strength of the component with an external thread, in N/mm. NOTE 1 A more accurate determination of the engagement depth (e.g. that of threaded rods) for blind bolted connections may be carr
37、ied out in accordance with VDI-Richtlinie (VDI Guideline) 2230. NOTE 2 Tightening of bolts as part of the design in blind bolted connections is only permitted if experimental-based verification is provided. For bolted connections which are not a bolt-nut assembly, the specifications relevant to bolt
38、ed connections with bolt-nut assemblies apply as appropriate. NCI re 3.13.1 Bolted connections made with studs Threaded studs and shear connector studs as specified in Table NA.1 shall be used. Threaded studs and shear connector studs not conforming to Table NA.1 shall be analysed as described in DI
39、N EN 1090-2:2008-12, 5.6.12. When determining the design resistance of joints using threaded studs and shear connector studs, the characteristic material strength values specified in Table NA.1 shall be used.

41、-2 See DIN EN 1993-1-1:2010-12, Table 3.1. NCI re 4.5.2 Limit value for effective throat thickness of fillet welds For flat products and open-section profiles with a material thickness t 3 mm, the effective throat thickness a of fillet welds shall satisfy the following condition: 5,0max ta , (NA.1)
42、with a and t expressed in mm. If the welding conditions permit, the condition under (NA.1) need not be satisfied; however, for a plate thickness, t 30 mm, a should not be less than 5 mm. NOTE Compliance with (NA.1) ensures that the cross sections of the weld and of jointed elements are compatible (c
43、f. 1 and 4). NCI re 4.5.3.2(6) For welds in components with a material thickness over 40 mm, the nominal ultimate tensile strength fuused shall be that for thicknesses up to 40 mm. NDP re 5.2.1(2) Note No further information regarding the classification of joints is provided. NCI re 6.2.7.1(13) and
44、6.2.7.1(14) Contact splice and compression force transfer (1) The compression force normal to the contact splice may be transferred completely by contact in cases b) and c) in Figure NA.1, provided that the faces of the splice are flat (saw cut), misalignment and the angle formed by splice faces (as
45、 illustrated in Figure NA.2) comply with the tolerances specified in DIN EN 1090-2, the splice faces are held in place by fasteners, the splice is formed by profiles of equal cross section. DIN EN 1993-1-8/NA:2010-12 8 Figure NA.1 Examples of contact splices: (a) partial contact; b) and c) full cont
46、act Figure NA.2 Angular deviation and misalignment ( 1/500; e 2 mm) (2) The design compressive strength in the splice face shall be taken as equal to that of the material of the connected components. (3) Analysis of the components to be connected shall make due allowance for forces and moments at th
47、e splice, and the possible occurrence of open joints. Where the components have the same cross-sectional shape at the splice, differing dimensions of cross sections due to the tolerances specified may be ignored. For case c) in Figure NA.1 this only applies if both components originate from the same
48、 delivery length. Otherwise, the design strength shall be reduced to 90 % in the analysis. (4) Tension is to be resisted by providing slip-free or welded joints. (5) Proof shall be provided to ensure that the transfer of shear at the splice is effected by fasteners only, no allowance being made for frictional forces. NOTE More information regarding contact splices will be found in 5. NDP re 6.2.7.2(9) Note DIN EN 1993-1-8:2010-12, Expression (6.2
