The course assumes that bespoke software will be used in many designs, but aims to present the background structural mechanics so the principles are understood, such that a manual design could be completed. Comment on the design of portal frame connections.The UK provisions for buildings close to a boundary.In-plane frame stability (the significance of second order effects), particularly when the Eurocode cannot be used.Discuss the preliminary sizing of portal frames.Discuss the loading in portal frames, from BS EN 1991.Introduce a range of practical issues which have a critical impact on the design of portal frames.The course aims to provide in-depth coverage of the major issues surrounding the analysis, design and (crucially) the detailing of portal frames. Despite the extensive history in portal frame design, some design issues are not well understood.
More recently, the Eurocodes are increasingly specified for design and are likely to be adopted more as software is released. For many years design has been in accordance with BS 5950.
Portal frames account for around 50% of the structural steel used in the UK.
