What are the main design Standards for steel structures in the UK?


Revised by Christophe Berre

There are seven main design Standards for steel structures in the UK. These Standards concern the design of pressure vessels, bridges, cranes, offshore installations and steelwork in building. Sections covered include limit state design, material properties, structural element design, joint design and testing.

PD 5500:2006 - Specification for unfired fusion welded pressure vessels
This Standard specifies requirements for the design, construction, inspection, testing and certification of unfired fusion welded pressure vessels manufactured from aluminium, and carbon, ferritic alloy and austenitic steels.

BS EN 13445: 2002 - Unfired pressure vessels
Part 3 of this Standard specifies the requirements for the design of unfired pressure vessels constructed of steel and their components. Design by formulae (DBF) and design by analysis (DBA) are covered and experimental techniques can also be used.

BS 5400:2000 - Steel, concrete and composite bridges
This Standard combines codes of practice to cover the design and construction of steel, concrete and composite bridges and the specifications for the loads, materials and workmanship.

BS EN 13001:2004 - Crane safety. General design
Part 1 of BS EN 13001 specifies the basis for computing stresses in crane structures and the way in which permissible stresses in crane structures shall be determined in order to secure economy in design and reliability in operation.

Offshore installations: Guidance on design, construction and certification (1990), Department of Energy, 1990 (REVOKED Aug 1998)
These guidance notes have been withdrawn but are a valuable source of information in the design of offshore structures.

BS 5950:2000(1990) - Structural use of steelwork in building
Part 1 of BS 5950 gives recommendations for the design of structural steelwork with hot rolled steel sections, flats, plates and hollow sections in buildings and allied structures. This Standard is also used for steelwork not specifically covered by other Standards.

BS EN 1993:2006 - Eurocode 3. Design of steel structures
This Eurocode specifies the general rules for the design of steel structures. Formulae are given for the design by calculation methods (DBC) and for design assisted by testing (DBT).
