Portal frames account for around 50% of the structural steel used in the UK. Despite their simple form, the design must address several complex challenges, including reversing bending moments, axial compression in slender members, second-order effects in flexible frames, and the need for effective restraints.

SCI Publication P399 is widely regarded as the backbone of portal frame design in the UK. With the publication of the second generation of Eurocodes, SCI has begun revising this guidance. This webinar will explore commonly misunderstood aspects of portal frame design and provide an overview of how the second generation of Eurocodes will influence current design practice.
