Full title and description

STB BS EN 1993-1-1:2005 + A1:2014 NA + A1:2014 — Eurocode 3: Design of steel structures — Part 1-1: General rules and rules for buildings, British adoption with Amendment A1 (2014) and the associated UK National Annex (NA). This publication brings together the 2005 EN 1993-1-1 text, Amendment A1:2014 and national application provisions used in the UK (National Annex).

Abstract

EN 1993-1-1 provides the fundamental design rules for steel structures used in buildings and civil engineering works. It sets out principles for safety, serviceability, durability and fire resistance of steel structures, including material properties, limit states, cross-section resistance, stability (global and local buckling), connections and general construction rules. The 2014 amendment (A1) introduces updates to normative references and adds provisions such as an Annex addressing execution class selection; the UK National Annex contains nationally-determined parameters and choices for application in the UK context.

Scope

This part of Eurocode 3 specifies general design rules and rules for buildings in steel. It covers the basis of design for steel structures (limit states, material properties and design values), rules for cross-sections and members, stability (including buckling and interaction), design of connections and assemblies, fatigue and fire design principles where applicable, and informative annexes providing additional methods and guidance. The standard is intended to be used together with EN 1990 (Basis of structural design) and relevant National Annexes that supply national choices and values.

Key topics and requirements

• Limit-state based design (ultimate and serviceability limit states) and verification procedures for steel members and structures.
• Material properties and partial safety factors for steel used in structural design.
• Design rules for cross-section resistance (tension, compression, bending, shear) including slenderness effects and section classification.
• Stability rules for members and frames (local buckling, global buckling, lateral torsional buckling) and interaction checks.
• Connection principles and design considerations for bolted and welded joints; detailing requirements for fabrication and erection (execution class selection covered in A1:2014).
• Guidance on durability, serviceability and basic fire design principles where relevant to structural steelwork.
• Normative and informative annexes supplying supplementary rules, interaction factors and example provisions.

Typical use and users

Primary users are structural and civil engineers, designers, architects involved in steel structure design, fabricators and manufacturers of steel components, construction contractors, and software vendors producing structural analysis/design tools. The standard is used for design calculations, specification of steelwork, preparation of construction drawings, and compliance with national building regulations when the National Annex is applied.

Related standards

EN 1993 is a multi-part Eurocode series. Related documents commonly used with EN 1993-1-1 include EN 1990 (Basis of structural design), other EN 1993 parts (e.g., parts on cold-formed sections, fatigue, stainless steels, design of joints), and the UK National Annex to EN 1993-1-1 which provides nationally determined parameters. Users should also consult amendments (A1:2014) and corrigenda that affect normative references and specific provisions.

FAQ

Q: What is this standard?

A: BS EN 1993-1-1:2005 + A1:2014 with National Annex is the British adoption of Eurocode 3 Part 1-1 (General rules and rules for buildings) with the 2014 amendment incorporated and national parameters provided by the UK National Annex. It defines the core design rules for steel building structures.

Q: What does it cover?

A: It covers limit-state design for steel members and structures (strength and serviceability), material and section properties, stability and buckling checks, basic connection design principles, and requirements for fabrication and erection; informative annexes give supplementary methods and guidance.

Q: Who typically uses it?

A: Structural and civil engineers, architects working with steel, steel fabricators and erectors, construction contractors, and software developers producing structural design tools. The document is also referenced by regulatory bodies and contractors for specification and compliance.

Q: Is it current or superseded?

A: The original EN 1993-1-1 text dates from 2005 and was formally amended by A1 in 2014; the BSI retail/adoption listing with NA reflects that consolidated edition. National standards bodies may publish later editions, corrigenda or national updates — always check your national standards body (e.g., BSI) for the most current status for your jurisdiction.

Q: Is it part of a series?

A: Yes — EN 1993 is a series (Eurocode 3) covering multiple parts for different aspects and materials (e.g., cold-formed sections, joints, fatigue, stainless steel). EN 1993-1-1 is the general rules part and is intended to be used in conjunction with other EN 1993 parts and EN 1990.

Q: What are the key keywords?

A: Eurocode 3, EN 1993-1-1, steel structures, limit states, buckling, connections, National Annex, BSI, amendment A1:2014, execution class.
