Design of Steel Portal Frames for Europe - SCI

The European Prestandard ENV 1993—1—1: Eurocode 3: Design of steel structures: Part 1.1
General rules and rules for buildings was published in 1992. The Steel Construction
Institute is in the process of preparing design guides to encourage the use of the Eurocodes
during their Prestandard or ENV periods. This publication will form part of a set of
design guides that will serve that purpose. It deals with steel portal framed buildings and
shows how to choose an efficient frame and prepare calculations to Eurocode 3.
The design principles presented in this publication are applicable for construction throughout
the European Economic Area (EU and EFFA), provided that the relevant National
Application Document of the country of use is complied with. The design guidance
includes additions to the Eurocode text derived from SC! P147 Plastic design of single
storey pitched roof portal frames to Eurocode 3, which was written as part of the Eureka
CIMsteel project.
Eurocode 3 may be more convenient than national standards in certain countries for the
design of steel portal frames. However, it is important that designers check that the key
requirements of the Eurocode on plastic design, Sections 5.2.1.4, 5.2.5 and 5.2.6.3, are
accepted in the National Application Document of the country where the structure is to be
erected. In some cases, the relevant national design standard may contain rules that are
compatible with this document instead. It is unlikely that Eurocode 3 will be used much
for the design of pitched roof portal frames to be constructed in the UK, because
BS 5950:1990 Structural use of steelwork in building: Part 1: Code of practice for design
in simple and continuous construction: ho: rolled sections gives greater economy in most
cases.
