Full title and description

E DIN EN 1993-1-1:2020-08 — Eurocode 3: Design of steel structures — Part 1-1: General rules and rules for buildings. Bilingual German/English draft edition (prEN 1993-1-1:2020) presenting the consolidated general design principles, material properties, cross-section rules, stability and connection rules for steel buildings.

Abstract

This document (draft edition published August 2020) sets out the basic design rules for steel structures and supplementary provisions specifically for buildings. It is intended for use together with EN 1990 (basis of structural design), EN 1991 (actions on structures) and other parts of EN 1992–EN 1999 where steel components are referenced. The draft was issued in German and English and later withdrawn/superseded pending the next consolidated edition.

• Number of pages: 234 pages (bilingual German/English layout).

Scope

EN 1993-1-1 provides general design rules applicable to steel structures in general and supplementary rules for buildings. The scope excludes design for fire (covered elsewhere) and special rules for certain civil engineering works such as bridges, towers, masts, silos, piling and offshore structures, which are addressed in other parts of the EN 1993 series. The standard is intended to be used in conjunction with EN 1990 and EN 1991 and with relevant product standards and execution standards such as EN 1090.

Key topics and requirements

• Fundamental design principles for steel structures including limit state design philosophy and partial safety factors.
• Material properties and classification of structural steels.
• Cross-section classification, resistance of cross-sections and members.
• Stability and buckling rules for members and frames (global and local stability checks).
• Design rules for connections: bolted, welded and mixed joints; workmanship and execution considerations.
• Rules for fatigue assessment where applicable to connections and details.
• Guidance on modelling, verification and interaction with actions from EN 1991.
• Reference to execution standards (for example EN 1090) and to other EN 1993 parts for special structures.

Typical use and users

Used by structural engineers, steelwork designers, detailers, fabricators, construction contractors, certification bodies and standards committees. Typical applications include the design and verification of steel building frames, structural members, connections, and the preparation of design documentation for execution and conformity assessment. Researchers and academic instructors also use this part of Eurocode 3 as the baseline for teaching steel design principles.

Related standards

Closely related documents include EN 1990 (Basis of structural design), EN 1991 (Actions on structures), other parts of EN 1993 (e.g., parts for fatigue, cold-formed members, towers/bridges), EN 1090 (execution of steel structures) and relevant national annexes or Nationally Determined Parameters (NDPs). The 2020 draft edition follows and updates principles from earlier EN 1993-1-1 editions and was later consolidated in subsequent EN 1993-1-1 editions (see note on supersession).

FAQ

Q: What is this standard?

A: This is the E DIN EN 1993-1-1:2020-08 draft edition of Eurocode 3 — Part 1-1 (General rules and rules for buildings). It presents the consolidated general design rules for steel buildings in a bilingual German/English draft format.

Q: What does it cover?

A: It covers fundamental design principles for steel structures, member and cross-section resistance, stability (buckling) checks, connection rules, fatigue considerations, material properties and guidance on using EN 1990 and EN 1991 alongside EN 1993. It does not include detailed fire design or specialised civil engineering structures (these are covered in other parts of EN 1993).

Q: Who typically uses it?

A: Structural engineers, steelwork designers, fabricators, contractors, certifiers, standards committees and academics involved in the design and execution of steel buildings.

Q: Is it current or superseded?

A: The 2020-08 draft edition was later withdrawn and is shown as superseded in catalogues; a consolidated new edition of DIN EN 1993-1-1 was published subsequently (reference: DIN EN 1993-1-1:2025-04 indicates the later consolidated edition). Users should consult the active consolidated EN 1993-1-1 edition and their national annex/NDP for current binding design rules.

Q: Is it part of a series?

A: Yes — EN 1993-1-1 is Part 1-1 of the EN 1993 series (Eurocode 3). The EN 1993 family contains multiple parts covering special topics such as fatigue, cold-formed members, towers, bridges and others; EN 1993 is intended to be used with EN 1990 and EN 1991.

Q: What are the key keywords?

A: Eurocode 3; steel structures; EN 1993-1-1; design rules; stability; connections; bolted joints; welded joints; partial factors; EN 1090; prEN.
