EN 1993 is intended to be used with Eurocodes EN 1990 - Basis of Structural Design, EN 1991 - Actions on structures and EN 1992 to EN 1999, when steel structures or steel components are referred to.
EN 1993-1 is the first of six parts of EN 1993 - Design of Steel Structures. It gives generic design rules intended to be used with the other parts EN 1993-2 to EN 1993-6. It also gives supplementary rules
applicable only to buildings.
EN 1993-1 comprises twelve subparts EN 1993-1-1 to EN 1993-1-12 each addressing specific steel components, limit states or materials.
It may also be used for design cases not covered by the Eurocodes (other structures, other actions, other materials) serving as a reference docmnent for other CEN TC's concerning structural matters.
EN 1993-1 is intended for use by
- committees drafting design related product, testing and execution standards,
- clients (e.g. for the fonnulation of their specific requirements)
- designers and constructors
- relevant authorities
Scope of Eurocode 3:
(1) 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.
(2) Eurocode 3 is concerned only with requirements for resistance, serviceability, durability and fire resistance of steel structures. Other requirements, e.g. concerning thennal or sOlmd insulation, are not covered.
(3) Eurocode 3 is intended to be used in conjunction with:
EN 1990 "Basis of structural design"
EN 1991 "Actions on structures"
ENs, ETAGs and ETA, for construction products relevant for steel structures
EN 1090 "Execution of Steel Structures - Technical requirement,"
EN 1992 to EN 1999 when steel structures or steel components are referred to
(4) Eurocode 3 is subdivided in various part"
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.
(5) EN 1993-2 to EN 1993-6 refer to the generic rules in EN 1993-1. TI,e rules in parts EN 1993-2 to EN 1993-6 supplement the generic rules in EN 1993-1.
(6) 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 1993-1-6 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 joint,.
EN 1993-1-9 Design of Steel Structures: Fatigne strength of steel structures.
EN 1993-1-10 Design of Steel Structures : Selection of steel for fracture touglmess 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.
Scope of Part 1.1 of Eurocode 3:
(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 steel buildings. These supplementary provisions are indicated by the letter "B" after the paragraph nmnber, thus ( )B.
(2) The following subjects are dealt with in EN 1993-1-1:
Section I: 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
(3) Sections I to 2 provide additional clauses to those given in EN 1990 "Basis of structural design".
(4) Section 3 deals with material properties of products made oflow alloy structural steels.
(5) Section 4 gives general rules for durability.
(6) Section 5 refers to the structural analysis of structures, in which the members can be modelled with sufficient accuracy as line element~ for global analysis.
(7) Section 6 gives detailed rules for the design of cross sections and members.
(8) Section 7 gives rules for serviceability.
