BS EN 1994-1-1:2004 describes the principles and requirements for safety, serviceability and durability of composite steel and concrete structures, together with specific provisions for buildings. It is based on the limit state concept used in conjunction with a partial factor method.
For the design of new structures, BS EN 1994-1-1 is intended to be used, for direct application, together with other parts of BS EN 1994, Eurocodes BS EN 1990 to 1993 and Eurocodes BS EN 1997 and 1998.
BS EN 1994-1-1 also serves as a reference document for other CEN TCs concerning structural matters.
BS EN 1994-1-1 is intended for use by:
- Committees drafting other standards for structural design and related product, testing and execution standards
- Clients (e.g. for the formulation of their specific requirements on reliability levels and durability)
- Designers and constructors
- Relevant authorities

Second Generation of EN Eurocode Standards
The second generation of EN Eurocode standards is expected to be published between 2023 and 2026. These documents are being published as soon as they are available, to enable users to prepare for the transition from the first generation to second generation of Eurocodes. As set out in the National foreword of the BS EN second generation Eurocodes, UK adoptions of the first generation of Eurocodes will be withdrawn by BSI on 30 March 2028. That means there is a period of coexistence between 2023 and 2028 during which both first and second generation Eurocodes are available.
Until 30 March 2028, the first generation documents should be considered as the applicable standards for buildings and civil engineering works constructed in the UK unless otherwise specified by the relevant authority or in the specification for a particular project. While the use of provisions in second generation Eurocodes in conjunction with first generation Eurocodes is not precluded, it should be undertaken with care and should only be done when users are satisfied that it will not result in a lower level of reliability than the minimum level set in the first generation Eurocodes and associated UK National Annexes.
