This Technical Guidance Note covers the design of concrete pad foundations, both mass and reinforced concrete forms. It will not, however, discuss how the bearing capacity of the soil is determined, as that is explained in Technical Guidance Note 19 (Level 1) Soil bearing capacity. It is suggested that you read that text in conjunction with this, in order to gain a more comprehensive understanding of the topic.
(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.
Thin panels of masonry in large buildings, or cavity wall skins, require additional horizontal support to make them stable. The element that provides this support is a vertical prop known as a ‘windpost’. Its principal role is to provide lateral support against destabilising horizontal forces that typically originate from wind pressure – hence, the name. Windposts are typically steel elements – either open sections, such as channels or angles, or closed sections, such as rolled hollow rectangular sections. This Technical Guidance Note provides guidance on the design and detailing of windposts relating to their incorporation into building structures.
This Technical Guidance Note aims to clarify the term 'simple connection' by explaining its use when designing connections within steel frames. Additionally, guidance is offered on different types of simple connection and the design checks that need to be carried out.
