Abstract

The purpose of this thesis has been to investigate, both analytically and
experimentally, the behaviour of bolted joints in cold formed steel members.
To this aim, the influences of all factors bearing a significant effect on behaviour of
bolted connections in cold formed steel assemblies and structures have been
investigated. Design expressions have been derived. With this information the
moment capacity of bolted joints can be calculated with considerably more accuracy
than the present existing expressionsin the current codeso f practice.
The findings of the thesis have already influenced the design expressions for bearing
strength of bolted connections in the European code of practice for design of cold
formed steel sections, i. e. Eurocode No 3, Annex A. It is hoped that the conclusions
drawn are further incorporated in the above mentioned code, and replace the
existing guidelines in the British Standard, BS 5950 Part 5, for the design of such
sections.
Furthermore for the first time ever, as a result of the analyses and experiments
carried out, designers are able to predict the moment-rotation relationship of such
connections without having to resort to testing. It is intended to feed this
information into design programmes to radically affect the elastic design of cold
formed steel structures. It should then be possible to design optimum structures by
specifying joints with appropriate characteristics.
