Execution of steel structures and aluminium structures - Part 4: Technical requirements for cold-formed structural steel elements and cold-formed structures for roof, ceiling, floor and wall applications
Abstract
This document specifies requirements for the execution, i.e. the manufacture and the installation, of cold-formed structural steel members and profiled sheeting and cold-formed structures for roof, ceiling, floor, wall and cladding applications. This document applies to structures designed according to the EN 1993 series. This document applies to structural members and profiled sheeting to be designed according to EN 1993 1 3. This document may be used for structures designed according to other design rules provided that conditions for execution comply with them and any necessary additional requirements are specified. This document also specifies requirements for the execution i.e. the manufacture and the installation of structures made from cold-formed profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading or seismic loading conditions and their documentation. This document covers structural profiled sheeting of Structural Class I and II and structural profiled sheeting in Structural Class III according to EN 1993 1 3 used in structures. NOTE 1 In National Annexes of EN 1993‑1‑3 specifications can be given regarding the use of the Structural Classes. This document covers structural members of all structural classes according to EN 1993‑1‑3. Structural profiled sheeting is understood here to be: - profiled sheet, such as trapezoidal, sinusoidal or liner trays (Figure 1). Structural members are understood here to be: - members (linear profiled cross sections) that are produced by cold forming (Figure 2). This document also covers: - not welded built-up sections (Figure 2d); - cold-formed closed and hollow sections including the welding of the longitudinal seam (Figure 2b and Figure 2c), not covered by EN 10219‑1; - perforated, punctured and micro profiled sheeting and members; The welding of built-up sections are not covered. The welding provisions are given in EN 1090 2. This document also covers spacer constructions between the outer and inner or upper and lower skins for roofs, walls and ceilings made from cold-formed profiled sheeting and the connections and attachments of the afore mentioned elements as long as all has a structural purpose. This document covers steel profiled sheeting for composite floors, e.g. during installation and in stage of pouring concrete. This document also covers the deconstruction of structures made from cold-formed profiled sheeting and structural members for roof, ceiling, floor and wall applications. Composite structural members 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 document. This document does not cover the necessary analyses and detailing and execution rules for thermal insulation, moisture protection, noise control and fire protection. This document does not cover regulations of roof cladding and wall cladding, produced by traditional plumber methods or tinsmith methods. This document does not cover detailed requirements for water tightness or air permeability resistance and thermal aspects of profiled sheeting. NOTE 2 The structures covered in this document can be for example. - single- or multi-skin roofs, whereby the load-bearing structure (lower skin) or the actual roof covering (upper skin) or both consist of cold-formed structural members and profiled sheeting; - single- or multi-skin walls whereby the load-bearing structure (inner skin), the actual cladding (outer skin) or both consist of cold-formed structural members and profiled sheeting, or - trusses from cold-formed members. NOTE 3 Structures can consist of an assembly of structural members and profiled sheeting made of steel according to EN 1090‑4 and of aluminium according to EN 1090‑5.
