Design of Braced Steel Frames with Ductile Partial-Strength Connections

This note provides guidance on the design of braced steel frames for buildings, utilising the significant moment resistance of unstiffened connections such as those shown in Fig 1. They do not provide full continuity but both BS 5950 and Eurocode 32 permit a ‘semi-continuous’ approach to design. These connections require only moderate fabrication effort and hence are relatively cheap. Semi-continuous framing is therefore becoming recognised as providing a more cost-effective approach than either simple or fully-continuous design. So far though, its application has been hindered by uncertainty over the extent of the benefits, by the failure of design Codes to provide methods to predict connection properties, and by lack of guidance on how to approach design of the frame as a whole. Guidance can now be provided on each of these aspects. Professor D. Anderson and A.F. Hughes
