This Technical Guidance Note concerns the derivation of wind load onto structures. It is based on Eurocode 1: Actions on Structures Part 1-4; General Actions – Wind Actions. With this being focused on a load that is sensitive to the environment, the UK Annex to the Eurocode plays a significant part as it makes reference to wind speeds that are unique to the British Isles. There are a large amount of variations and conditions the designer must be aware of when determining wind loads on structures. It is for this reason that the reader is referred to the code text more often than in other notes in this series.
This Technical Guidance Note explains the basic principles of below ground drainage for both surface and foul water. Acting as an introduction, it describes the different types of drainage pipes that are available, how they are installed, how they interface with structure, their testing and maintenance.
This Technical Guidance Note describes the basic knowledge required to read drawings produced by structural engineers.
