In the Eurocode series of European standards (EN) related to construction, Eurocode 3: Design of steel structures (abbreviated EN 1993 or, informally, EC 3) describes how to design steel structures, using the limit state design philosophy.
It was approved by the European Committee for Standardization (CEN) on 16 April 2004. Eurocode 3 comprises 20 documents dealing with the different aspects of steel structure design:
EN 1993-1-1: General rules and rules for buildings. EN 1993-1-2: General rules - Structural fire design. EN 1993-1-3: General rules - Supplementary rules for cold-formed members and sheeting. EN 1993-1-4: General rules - Supplementary rules for stainless steels. EN 1993-1-5: General rules - Plated structural elements. EN 1993-1-6: General rules - Strength and stability of shell structures. EN 1993-1-7: General rules - Strength and stability of planar plated structures subject to out of plane loading. EN 1993-1-8: Design of joints. EN 1993-1-9: Fatigue. EN 1993-1-10: Material toughness and through-thickness properties. EN 1993-1-11: Design of structures with tension components. EN 1993-1-12: General - High strength steels. EN 1993-2: Steel bridges. EN 1993-3-1: Towers, masts and chimneys – Towers and masts. EN 1993-3-2: Towers, masts and chimneys – Chimneys EN 1993-4-1: Silos EN 1993-4-2: Tanks EN 1993-4-3: Pipelines EN 1993-5: Piling EN 1993-6: Crane supporting structures
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. It is only concerned with requirements for resistance, serviceability, durability and fire resistance.
Eurocode 3 is intended to be used in conjunction with: EN 1990: Eurocode - Basis of structural design; EN 1991: Eurocode 1 - 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.
Part 1-1: General rules and rules for buildings
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.

Part 1-2: General rules - Structural fire design
EN 1993-1-2 deals with the design of steel structures for the accidental situation of fire exposure and it has to be used in conjunction with EN 1993-1-1 and EN 1991-1-2. This part only identifies differences from, or supplements to, normal temperature design. EN 1993-1-2 deals only with passive methods of fire protection.
Part 1-3: General rules - Supplementary rules for cold-formed members and sheeting
EN 1993-1-3 gives design requirements for cold-formed thin gauge members and sheeting. It applies to cold-formed steel products made from coated or uncoated thin gauge hot or cold rolled sheet or strip, that have been cold-formed by such processes as cold-rolled forming or press-braking. It may also be used for the design of profiled steel sheeting for composite steel and concrete slabs at the construction stage, see EN 1994. The execution of steel structures made of cold-formed thin gauge members and sheeting is covered in EN 1090.
Part 1-4: General rules - Supplementary rules for stainless steels
EN 1993-1-4 deals with the additional requirements for the design of steel structures made of stainless steel and it has to be used in conjunction with EN 1993-1-1 and EN 1993-1-3.
Part 1-5: Plated structural elements
EN 1993-1-5 gives design requirements of stiffened and unstiffened plates which are subject to inplane forces.
Part 1-6: Strength and Stability of Shell Structures
EN 1993-1-6 gives design requirements for plated steel structures that have the form of a shell of revolution.
Part 1-7: General Rules - Supplementary rules for planar plated structural elements with out of plane loading
EN 1993-1-7: provides principles and rules of application for the structural design of stiffened and unstiffened plates loaded with out of plane actions and it has to be used in conjunction with EN 1993-1-1.
