This Technical Guidance Note explains how rolled steel I and H-sections are designed to resist torsion.
This note focuses on the design of columns in simple construction to BS EN 1993-1-1 – Eurocode 3: Design of Steel Structures – Part 1-1: General Rules for Buildings . It covers rolled steel ‘I’ and ‘H’ sections acting as columns within a braced steel frame structure.
This note addresses the design of solid and glulam timber elements that are unrestrained against lateral torsional buckling. It explains how such beams are analysed and designed. The impact of notching the supports of beams is also considered with respect beam's shear capacity.
