EN 1991–EN 1999 (Eurocodes) are the European structural design standards for buildings and civil works. They cover loads, materials, stability, earthquake resistance, and structural design. Below you’ll discover what each code covers and how to access the official standards.

What Are the Eurocodes EN 1991–1999?

The Eurocodes are a set of European harmonized standards aiming to unify structural design rules across the EU, ensuring safety, durability, and regulatory compliance.

Main Eurocodes Overview

  • EN 1991: Actions on structures – loads including self-weight, snow, wind, and live loads.
  • EN 1992: Design of concrete structures.
  • EN 1993: Design of steel structures.
  • EN 1994: Design of composite steel and concrete structures.
  • EN 1995: Design of timber structures.
  • EN 1996: Design of masonry structures.
  • EN 1997: Geotechnical design.
  • EN 1998: Earthquake-resistant design / seismic actions.
  • EN 1999: Design of aluminium structures.

Why Use EN 1991–1999 (Eurocodes)?

  • Provides harmonized structural rules across the EU, replacing former national codes.
  • Covers materials, loads, fire, seismic resistance, and geotechnical design.
  • Ensures compliance with EU regulations and simplifies cross-border construction projects.
  • Supports flexible design with concrete, steel, timber, aluminium, masonry, or composite structures.

Which Eurocode Applies to My Project?

  • Concrete buildings → EN 1992 + EN 1991
  • Steel structures → EN 1993 + EN 1991
  • Composite steel-concrete → EN 1994 + EN 1991
  • Timber → EN 1995 + EN 1991
  • Masonry → EN 1996 + EN 1991
  • Seismic zones → EN 1998 + relevant material code + EN 1991
  • Aluminium structures → EN 1999 + EN 1991

FAQ: EN 1991–EN 1999 (Eurocodes)

What are the Eurocodes?

The Eurocodes (EN 1990–EN 1999) harmonize structural design rules for buildings and civil works across Europe, covering loads, materials, seismic, and geotechnical aspects.

Why should I use Eurocodes instead of national codes?

Eurocodes provide harmonized design rules accepted across the EU, simplifying cross-border projects, ensuring compliance with EU regulations, and replacing fragmented national codes.

Do Eurocodes cover all materials and structures?

Yes — Eurocodes cover concrete, steel, aluminium, timber, masonry, composite structures, geotechnical and seismic design for most construction types.

Is EN 1990 required with EN 1991–1999?

Yes. EN 1990 defines principles, safety, serviceability, and durability requirements that form the basis for applying EN 1991–1999 in structural design.
