BS EN 15048-1:2016EN 15048-1:2016 (E) 5 Introduction Rules for design and execution of bolted connections with non-preloaded structural bolts are defined for instance in EN 1993-1-8 and EN 1090-2 for steel structures or EN 1999-1-1 and EN 1090-3

23、for aluminium or aluminium alloy structures. The parts of this European Standard on structural bolting assemblies specify the general requirements which ensure that bolting assemblies comprising bolts and nuts are suitable for use as non-preloaded structural bolting in structural metallic works. The

24、y can be used in shear connections and/or in tension connections if no preload is required. Structural bolting assemblies which meet the requirements of this part of this European Standard have been designed to allow tensile resistance of at least fub As. For this purpose the tensile test of bolting

25、 assemblies specified in EN 15048-2 is a mean to check whether the function of the assembly is fulfilled. Washers or other elements can be used additionally if necessary. BS EN 15048-1:2016EN 15048-1:2016 (E) 6 1 Scope This part of this European Standard specifies the general requirements for boltin

26、g assemblies for non-preloaded structural bolting. Bolting assemblies in accordance with this European Standard are designed to be used in structural bolting connections for shear and/or tensile loading. The intended use of bolting assemblies in accordance with this European standard is structural m

27、etallic works. It applies to bolts (the term used when bolts partially threaded, screws, studs and stud-bolts are considered all together) and nuts made of carbon steel, alloy steel, stainless steel or aluminium or aluminium alloy with the following property classes: bolts made of carbon steel or al

28、loy steel: 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9 (in accordance with EN ISO 898-1); nuts made of carbon steel or alloy steel: 5, 6, 8, 10, 12 (in accordance with EN ISO 898-2); bolts made of austenitic stainless steel: 50, 70, 80 (in accordance with EN ISO 3506-1); nuts made of austenitic stainless ste

29、el: 50, 70, 80 (in accordance with EN ISO 3506-2); bolts made of aluminium or aluminium alloy: AL1 to AL6 (in accordance with EN 28839); nuts made of aluminium or aluminium alloy: AL1 to AL6 (in accordance with EN 28839). This European Standard applies to bolting assemblies with ISO metric coarse pi

30、tch thread from sizes M12 to M39 for use in steel structures according to EN 1090-2, and from M5 to M39 for use in aluminium or aluminium alloy structures according to EN 1090-3. The use of thread sizes larger than M39 is not precluded provided all applicable requirements of this standard are met. W

31、ARNING Only bolting assemblies are covered by this harmonized standard: separate bolts or nuts, not tested as part of an assembly lot of bolting assemblies in accordance with EN 15048-2, are not covered by this harmonized standard and cannot be CE marked. NOTE 1 The property classes 4.8, 5.8 and 6.8

32、 may be subjected to limitations of use. NOTE 2 High-strength structural bolting assemblies for preloading which meet the requirements of EN 143991 are not within the scope of this European Standard but they are also suitable for use in non-preloaded structural bolting. NOTE 3 Bolts and nuts made of

33、 aluminium or aluminium alloys are not designed to be used in steel structures, see EN 10902. Bolting assemblies in accordance with this European Standard are not designed to be welded. Railway rail fasteners are not covered by this European Standard. 2 Normative references The following documents,

Therefore, the requirements specified in 4.2, 4.3 and 4.4 are assessed through the verification of the pr

47、operties of the involved components and/or bolting assemblies, as applicable. 4.2 Type (bolting assemblies) 4.2.1 General Type “SB“ linked with the property class of the bolt covers the axial load of the structural bolting assembly assumed in design. The geometry of the head is relevant for the abil

48、ity of the bolting assembly to be loaded by tension. The cross section of the shank is relevant for the ability of the bolting assembly to be loaded by shear. Any suitable head shape and shank dimensions may be used provided that the requirements for tensile resistance are met. 4.2.2 Axial load (bol

49、ting assemblies) Bolting assemblies shall be assessed in accordance with 5.2. The minimum tensile resistance of the bolting assembly shall comply with the values specified in Table 1, Table 2 and Table 3. The values correspond to the minimum tensile strength Rm,minfor the relevant property class of the structural bolting assembly, as specified in EN ISO 898-1, EN ISO 3506-1 or EN 28839 as appropriate.
