Technical Guidance Note (Level 1, No. 16): Lateral torsional buckling

Once the concept and scheme design has been determined, initial sizing of elements commences. This note shows how to size elements, prior to detailed design. This process allows the engineer to gain an appreciation of structural form.

There are several variations and conditions the designer must be aware of when determining wind loads on structures. Based on Eurocode 1: Actions on Structures Part 1-4; General Actions – Wind Actions , this note draws on the UK National Annex as it makes reference to wind speeds that are unique to the UK.

This note describes the basic knowledge required to read structural drawings.
