EN 1993-1-2:2005 Eurocode 3: Design of steel structures - Part 1-2: General rules - Structural fire design Incorporating Corrigendum December 2005 [Superseded: CEN ENV 1993-1-2]
1.1.1 Scope of EN 1993
(1) EN 1993 applies to the design of buildings and civil engineering works in steel. It complies with the
principles and requirements for the safety and serviceability of structures, the basis of their design and
verification that are given in EN 1990 – Basis of structural design.
(2) EN 1993 is only concerned with requirements for resistance, serviceability, durability and fire
resistance of steel structures. Other requirements, e.g concerning thermal or sound insulation, are not
considered.
(3) EN 1993 is intended to be used in conjunction with:
– EN 1990 “Basis of structural design”
– EN 1991 “Actions on structures”
– hEN´s for construction products relevant for steel structures
– EN 1090 “Execution of steel structures”
– EN 1998 “Design of structures for earthquake resistance”, where steel structures are built in seismic
regions
(4) EN 1993 is subdivided in six parts:
– EN 1993-1 Design of Steel Structures : Generic rules.
– EN 1993-2 Design of Steel Structures : Steel bridges.
– EN 1993-3 Design of Steel Structures : Towers, masts and chimneys.
– EN 1993-4 Design of Steel Structures : Silos, tanks and pipelines.
– EN 1993-5 Design of Steel Structures : Piling.
– EN 1993-6 Design of Steel Structures : Crane supporting structures.
1.1.2 Scope of EN 1993-1-2
(1) EN 1993-1-2 deals with the design of steel structures for the accidental situation of fire exposure and is
intended to be used in conjunction with EN 1993-1-1 and EN 1991-1-2. EN 1993-1-2 only identifies
differences from, or supplements to, normal temperature design.
(2) EN 1993-1-2 deals only with passive methods of fire protection.
(3) EN 1993-1-2 applies to steel structures that are required to fulfil this load bearing function if exposed to
fire, in terms of avoiding premature collapse of the structure.
NOTE: This part does not include rules for separating elements.
(4) EN 1993-1-2 gives principles and application rules for designing structures for specified requirements
in respect of the load bearing function and the levels of performance.
(5) EN 1993-1-2 applies to structures, or parts of structures, that are within the scope of EN 1993-1 and are designed accordingly.
(6) The methods given are applicable to structural steel grades S235, S275, S355, S420 and S460 of
EN 10025 and all grades of EN 10210 and EN 10219.
(7) The methods given are also applicable to cold-formed steel members and sheeting within the scope of
EN1993-1-3.
(8) The methods given are applicable to any steel grade for which material properties at elevated
temperatures are available, based on harmonized European standards.
(9) The methods given are also applicable stainless steel members and sheeting within the scope of EN
1993-1-4.
NOTE: For the fire resistance of composite steel and concrete structures, see EN 1994-1-2.
