Eurocode 3 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.
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.
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 1090-1, Execution of steel structures and aluminium structures – Part 1: Requirements for conformity assessment of structural components
EN 1090-2, Execution of steel structures and aluminium structures – Part 2: Technical requirements for steel structures
EN 1992 to EN 1999 when steel structures or steel components are referred to
Eurocode 3 is subdivided in various parts:
EN 1993-1 Design of Steel Structures : General rules and rules for buildings.
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.
EN 1993-2 to EN 1993-6 refer to the generic rules in EN 1993-1. The rules in parts EN 1993-2 to EN 1993-6 supplement the generic rules in EN 1993-1.
EN 1993-1 “General rules and rules for buildings” comprises:
EN 1993-1-1 Design of Steel Structures : General rules and rules for buildings.
EN 1993-1-2 Design of Steel Structures : Structural fire design.
EN 1993-1-3 Design of Steel Structures : Cold-formed members and sheeting.
EN 1993-1-4 Design of Steel Structures : Stainless steels.
EN 1993-1-5 Design of Steel Structures : Plated structural elements.
EN 1993-1-6 Design of Steel Structures : Strength and stability of shell structures.
EN 1993-1-7 Design of Steel Structures : Strength and stability of planar plated structures transversely loaded.
EN 1993-1-8 Design of Steel Structures : Design of joints.
EN 1993-1-9 Design of Steel Structures : Fatigue strength of steel structures.
EN 1993-1-10 Design of Steel Structures : Selection of steel for fracture toughness and through-thickness properties.
EN 1993-1-11 Design of Steel Structures : Design of structures with tension components made of steel.
EN 1993-1-12 Design of Steel Structures : Supplementary rules for high strength steel.
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 steel buildings. These supplementary provisions are indicated by the letter “B” after the paragraph number, thus ( )B.
NOTE For cold formed members and sheeting, see EN 1993-1-3.
The following subjects are dealt with in EN 1993-1-1:
Section 1: General
Section 2: Basis of design
Section 3: Materials
Section 4: Durability
Section 5: Structural analysis
Section 6: Ultimate limit states
Section 7: Serviceability limit states
Sections 1 to 2 provide additional clauses to those given in EN 1990 “Basis of structural design”.
Section 3 deals with material properties of products made of low alloy structural steels.
Section 4 gives general rules for durability.
Section 5 refers to the structural analysis of structures, in which the members can be modelled with sufficient accuracy as line elements for global analysis.
Section 6 gives detailed rules for the design of cross sections and members.
Section 7 gives rules for serviceability.
