Steel Buildings in Europe

Part 10: Model Construction Specification 10 - 17 5 DESIGN OF STEEL STRUCTURES Eurocode 3 is intended to be used in conjunction with:  EN 1990 Basis of structural design  EN 1991 Actions on structures  ENs, ETAGs and ETAs for construction products relevant for steel structures  EN 1090 Execution of Steel Structures – Technical requirements  EN 1992 to EN 1999 when steel structures or steel components are referred to. Eurocode 3 is concerned only with requirements for resistance, serviceability, durability and fire resistance of steel structures. Other requirements, e.g. concerning thermal or sound insulation, are not covered. 5.1 Rules for single-storey buildings – EN 1993-1-1 EN 1993-1-1 gives basic design rules for steel structures with material thicknesses t > 3 mm. It also gives supplementary provisions for the structural design of single-storey steel buildings. Material properties for steels and other construction products and the geometrical data to be used for design shall be those specified in the relevant ENs, ETAGs or ETAs unless otherwise indicated. National choice is allowed through clauses listed in the Foreword to EN 1993-1-1. Additional contract document requirements The design working life shall be taken as the period for which a building structure is expected to be used for its intended purpose. For the specification of the intended design working life of a permanent building see Table 2.1 of EN 1990. The effects of deterioration of material, corrosion or fatigue where relevant shall be taken into account by appropriate choice of material, see EN 1993-1-4 and EN 1993-1-10, and details, see EN 1993-1-9, or by structural redundancy and by the choice of an appropriate corrosion protection system. The dimensional and mass tolerances of rolled steel sections and plates shall comply with the relevant product standard, ETAG or ETA unless more severe tolerances are specified. Any semi-finished or finished structural product used in the structural design of buildings shall comply with the relevant EN Product Standard or ETAG or ETA.
