Modern building services cost up to three times as much as the structural steelwork in a typical commercial building. Steel frame design needs to be considered in the context of the overall building cost, where early design decisions concerning structural layouts have a significant impact on the building services.
This article discusses connection behaviour, design methodology and the classifications given in BS EN 1993-1-8. Connection design for structural integrity and the use of preloaded assemblies are introduced. Challenges connected with multi-member or unorthodox connections are also discussed.
The provision of beams with web openings has become a common method of incorporating services within the structural depth of a floor. Although specialist software is available to design such beams, guidance regarding sizing, spacing and best practice is useful for engineers performing scheme design.
