Description

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.

Scope

Eurocode 4 applies to the design of composite structures and members for buildings and civil engineering works. 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.

Eurocode 4 is concerned only with requirements for resistance, serviceability, durability and fire resistance of composite structures. Other requirements, e.g. concerning thermal or sound insulation, are not considered.

Eurocode 4 is intended to be used in conjunction with: 

• EN 1990 Eurocode: Basis of structural design
• EN 1991 Eurocode 1: Actions on structures
• ENs, hENs, ETAGs and ETAs for construction products relevant for composite structures
• EN 1090 Execution of steel structures and aluminium structures
• EN 13670 Execution of concrete structures
• EN 1992 Eurocode 2: Design of concrete structures
• EN 1993 Eurocode 3: Design of steel structures
• EN 1997 Eurocode 7: Geotechnical design
• EN 1998 Eurocode 8: Design of structures for earthquake resistance, when composite structures are built in seismic regions.

Eurocode 4 is subdivided in various parts:

• Part 1-1: General rules and rules for buildings
• Part 1-2: Structural fire design
• Part 2: Bridges.
