Technical Guidance Note (Level 1, No. 6): Notional loading (Equivalent Horizontal Forces)

This Technical Guidance Note concerns the derivation of snow load onto structures. It is based on Eurocode 1: Actions on Structures Part 1-3; General Actions – Snow Loads. With this Eurocode being focused on an action that is sensitive to environmental effects, the UK annex to it plays a significant role, as it makes reference to projected snow falls that are unique to the British Isles. There are a large number of variations and conditions the designer must be aware of when determining snow loads onto structures. As such, the reader is referred to the code text more frequently than in other Technical Guidance Notes. (This article was updated in October 2016 to reflect errata issued since its original publication.)

An introduction to ground bearing floor slabs, touching on the slabs' reinforcement by considering both historical use of mesh as well as current plastic and steel fibre reinfocement methods.

Recently, the technology behind post fix anchors has become increasingly complex. This guidance note has been developed in order to provide some clarity around the multitude of options that can be presented to a designer required to specify anchors.
