32、secretariat of which is held by SN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2017, and conflicting national standards shall be withdrawn at the latest by September 2017. Attention

33、 is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

37、he following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Nether

38、lands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 1090-5:2017EN 1090-5:2017 (E) 7 1 Scope This European Standard specifies requirements for the execution i.e. the manufacture and the installation of cold-formed stru

39、ctural aluminium components made from profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading conditions or seismic loading conditions and their documentation. It does cover products of structural class I and II according to EN 1999-1-4 used in structures.

40、 Structural elements are understood here to mean profiled sheeting, such as trapezoidal, sinusoidal, liner trays or cassette profiles (Figure 1), that are produced by cold forming. Perforated and micro profiled sheeting are also covered by this part. Welded sections are excluded from this part and a

41、re covered by EN 1090-3 except seal welding in low-stress areas. This standard also covers spacer constructions between the outer and inner or upper and lower skins as well as supporting members for roofs, walls and ceilings made from cold-formed profiled sheeting and the connections and attachments

42、 of the afore mentioned elements as long as they are involved in load transfer, it also covers connections and attachments of these elements. A combination of steel and aluminium structural elements are permitted, e.g. liner trays made of steel, stiffened by profiles made of aluminium. In this case,

43、 EN 1090-4 and this document apply. Composite structural elements where the interaction between dissimilar materials are an integral part of the structural behaviour such as sandwich panels and composite floors are not covered by this standard. NOTE The structures covered in this standard can be for

44、 example single- or multi-skin roofs, whereby the load-bearing structure (lower skin) as well as the actual roof covering (upper skin) or both consist of structural elements; single- or multi-skin walls whereby the load-bearing structure (inner skin) as well as the actual cladding (outer skin) or bo

45、th consist of structural elements; or suspended ceilings for interior fitting.
