Portal frames account for around 50% of the structural steel used in the UK. Despite the extensive history in portal frame design, some design issues are not well understood.
The course aims to provide in-depth coverage of the major issues surrounding the analysis, design and (crucially) the detailing of portal frames. The course covers frame design to BS EN 1993-1-1.
The objectives of this course are to:
• Introduce a range of practical issues which have a critical impact on the design of portal frames;
• Discuss the loading in portal frames, from BS EN 1991;
• Discuss the preliminary sizing of portal frames;
• Clarify the Eurocode provisions for:
In-plane frame stability (the significance of second order effects);
Member stability and restraints;
Haunch resistance;
Serviceability checks;
The UK provisions for buildings close to a boundary.
• Comment on the design of portal frame connections;
• Discuss the deflection criteria.
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.
